Whey protein is a popular supplement for the many out there who exercise or take their health and fitness seriously. It helps with building muscle, recovery, and provides essential amino acids that support your body in many of its functions. On the other hand, though, many whey protein supplements are high in calories and have a high sugar content. 

In comes PhD Nutrition Diet Whey Protein, which claims to be different than traditional whey protein powders. For starters, it has less calories and carbs than other protein supplements. It also consists of more CLA, flaxseed, and L-Carnitine than other options. This product is meant for increasing lean muscle mass while reducing body fat.

In this PhD Nutrition Diet Whey Protein review, we’re going to talk about what we found when we took a closer look at this diet Whey powder. We’ll go over what’s in it, how it tastes, who should use it, and more. Read on to find out if PhD Diet Whey Protein Powder is a good fit for you and how our review experience came out.

What Is PhD Diet Whey Protein Powder?

PhD Nutrition Diet Whey Protein is a protein supplement from PhD Performance Nutrition, the same producers as well-known testosterone booster PhD Test Matrix . PhD Nutrition Diet Whey Protein combines ingredients for targeting muscle building with those that support increases in energy and fat loss. It’s a high-protein, low-calorie blended supplement designed to help people reach their fitness goals.

The idea is not to put on a lot of fat when you’re working on toning your muscles. PhD keeps the carbohydrates and calories low, but the protein high in a serving of its PhD Diet Whey Protein Powder. PhD adds other ingredients that boost energy, increase fat burning, and promote better digestive health.

How Does PhD Nutrition Diet Whey Protein Compare?

PhD Diet Whey Protein Powder has 91 calories per 25 gram serving of the supplement. Traditional whey protein supplements often have anywhere from 110 to 160 calories per serving; for example, you’ll find 130 calories per serving in Bowmar Nutrition Whey Protein and 160 calories per serving in Gnarly Whey . The tricky thing to remember when you’re comparing protein powder supplements is to look at the serving size. They may not be the same.

PhD Nutrition Diet Whey Protein has less than 2 grams of fat and less than 3 grams of carbs per serving. The fat content and carbohydrates of other protein powders varies widely across the board. 

PhD sets their product apart by adding more of certain ingredients to help boost the effectiveness of their protein powder. So, let’s take a look at what’s in this protein supplement.

PhD Diet Whey Protein Powder Ingredients

The ingredients in PhD Diet Whey Protein Powder add for extra muscle building, and fat burning power are CLA, flaxseed, and L-Carnitine. So, let’s talk about those and what they bring to the table.

• CLA (Conjugated Linoleic Acid) – CLA is an omega-6 fatty acid that has many benefits for your body. Research shows there may be a link between CLA and weight loss. It decreases the amount of body fat you have. Other benefits may include preventing cancer and type 2 diabetes, as well as heart disease. 
• Flaxseed – Ground flaxseed improves your digestive system. It’s high in fiber and consists of omega-3 fatty acids. People use flaxseed to relieve constipation. It’s thought to lower the bad cholesterol level, too. 
• L-Carnitine – This amino acid improves cognitive function and stimulates weight loss. L-Carnitine is said to convert fat into energy for your body. The fatty acids enter the mitochondria (power producer in cells), where they are burned to create an energy source. 

PhD Nutrition Diet Whey Protein has 750 milligrams of flaxseed powder per serving. It also has 375 milligrams of CLA and 125 milligrams of L-Carnitine. 

PhD Diet Whey Protein Powder Flavors

PhD Nutrition Diet Whey Protein comes in more flavors than most other protein supplement brands. Here’s a list of their inventive flavors:

• Vanilla Creme
• Belgian Chocolate
• White Chocolate
• Chocolate Mint
• Lemon & Blueberry
• Salted Caramel
• Chocolate Peanut
• Cookies & Cream
• Chocolate Orange
• Royal Milk Tea
• White Chocolate & Raspberry
• Birthday Cake

Keep in mind some of the ingredients and nutritional information may vary a little from one flavor to another.

PhD Diet Whey Protein Powder Customer Reviews

We’re all different, but it’s helpful to hear what others who already use the protein have to say about their results and how the product tastes. 

For the most part, users say they like the taste of the protein. Overall, Banana appears to be one of the favorite flavors. Belgian Chocolate and Vanilla Crème are also popular. Most reviewers say the mixture comes out thick but without lumps. The one common negative was from users saying the flavors taste too sweet. 

Customers of this product say it works well to keep them full. It blends easily and has a smooth texture. They also mostly say it’s excellent for providing the nutrition they’re looking for. It’s a good value.

Users say they like the boost they get for their recovery when having this protein supplement. Generally, people like PhD Nutrition Diet Whey Protein as a post-workout supplement .

Who is PhD Nutrition Diet Whey Protein Best For?

PhD Diet Whey Protein Powder is the ideal supplement for people looking to gain lean muscle mass while cutting body fat. It’s high protein but low calorie and sugar. 

Though it’s not the right choice to include for anyone looking to bulk up. PhD Diet Whey Protein Powder isn’t engineered to add bulk to someone. While it supports muscle recovery and growth, it isn’t mixed for building large muscles. 

Some people are allergic to whey protein. If you know you are or have a sensitivity to it, do not use PhD Nutrition Diet Whey Protein.

Is PhD Nutrition Diet Whey Protein Safe?

No protein supplement should be taken in excess. Too much of the added ingredients could result in negative side effects. But we want to focus on any possible side effects from using the supplement as intended.

Users report some instances of belly aches, cramping, and diarrhea. Some people said they felt sick after drinking their protein shakes. These are symptoms that many may experience when they drink protein supplements. PhD Nutrition Diet Whey Protein doesn’t have a lot of this reported, but there are some users indicating these side effects. 

Is There Data to Back Up PhD Nutrition Diet Whey Protein?

There is scientific research that supports the benefits of specific ingredients in PhD Nutrition Diet Whey Protein. What we don’t see are any studies done by third parties of the product itself. PhD has yet to come out with any proof their supplement does what it says it can.

Where to Buy PhD Diet Whey Protein Powder

PhD Diet Whey Protein Powder is available in 3 sizes, with savings at each level. We will detail the pricing and savings below.

PhD Nutrition Diet Whey Protein Pricing:

• 500G –  £12.74 / $17.12 (save 15%)
• 1KG –  £19.19 / $25.78 (save 40%)
• 2KG – £29.50 / $39.64 (save 50%)

With three sizes/pricing tiers, savings at each order level, and 14 flavors to choose from (including options like Birthday Cake and Salted Caramel), there seems to be something for everyone when it comes to PhD Nutrition Diet Whey Protein.

Claims vs. Reality

PhD claims their Diet Whey Protein Powder is formulated with a high-protein, low-calorie blend. Which it does, at first glance. When you compare this supplement to other protein powders , make sure you look at the serving size indicated on the package. You want to make your comparison across a level playing ground.

The company also claims these powders have “market-leading taste and mixability.” The mixability does check out. Customers report it is easy to mix, and you aren’t left with lumps. The claim on taste isn’t full proof. There are reports that users like the taste. However, some users also report a fake or unpleasant taste.

The final claim we’ll look at is that PhD adds more CLA, flaxseed, and L-Carnitine than other brands. This claim is supported. The ingredients in protein powders vary widely across different brands of supplements. Some makers keep ingredient levels a secret due to proprietary formulas, but we can usually see if an ingredient is part of a supplement.

Conclusion: PhD Nutrition Diet Whey Protein Review

PhD Diet Whey Protein Powder is a high-quality supplement that works as a meal replacement or a post-workout recovery drink. The flavor assortment is large, meaning there is a flavor out there for everyone’s taste buds to enjoy.

PhD Nutrition Diet Whey Protein is also ideal for anyone looking to promote more lean muscle mass and less body fat. The added ingredients are targeted at trimming off fat while helping muscles recover quicker. While it is a good protein supplement, it isn’t right for everyone. You may need to do some tasting to find the right flavor, also.

In short, we think PhD Nutrition Diet Whey Protein is a good quality protein supplement that may not be right for everyone, but will work well for some.

Best whey protein powders to fuel muscle growth

By Michael Sawh and Aaron Toumazou

With gyms and fitness studios reopening their doors, here are the whey protein powders that'll help you hit the ground running as you reacquaint yourself with the squat rack

There's a reason why everyone bigger than you in the gym is lugging around a protein shaker with their gym towel and water bottle . Incorporating whey protein into your training cycle helps up your intake of that all-important macronutrient credited with bulking, getting stronger and maintaining lean muscle mass.

Whether you choose to consume it before or after your workout, consuming a whey protein supplement alongside a good diet and structured training will help form a stronger base to keep the gains train moving. Not only that, it'll also give your body a boost when it comes to recovering from a tough session in the gym or heading out for a lung-busting double-digit-mile run.

Whey protein comes in many different forms and flavours, with more and more brands offering their own unique blend. While choice is always a good thing, it does make knowing what to look for in the supplement all that more challenging. Which is why we've put together a few pointers on what to pay attention to when upping your protein intake with a whey protein powder, along with the best options to get shaking. 

What different types of whey protein are there?

While most whey protein supplements come in powder form, ready to be mixed with cold water, milk or your preferred plant-based alternative, different types of whey protein go through different processing methods to offer purer and less pure strains.

Isolate whey protein usually contains the strongest percentage of protein, along with a lower level of fat, carbohydrate and lactose content per serving. With whey protein concentrate, that protein percentage drops slightly, while fat and carbohydrate content jumps up and can offer more in the way of flavour to make it a little more enjoyable to consume.

There’s also hydrolysate whey protein, which is considered a more pure form of protein that has been shown to be absorbed much quicker by the body to start going to work. That ability to quickly release that whey protein into the body does mean you’ll likely need to pay more to benefit from it, though.

What other whey protein ingredients should you look for?

Along with the whey, most protein powders will also pack in a range of different ingredients that your body may or may not love. Pay attention to the level of sugar and fat content in single servings to make sure you’re also not putting a lot of bad stuff into your body too, and if lactose is an issue for you, you'd be much better off considering the vegan protein powder alternative.

A strong presence of natural ingredients is always favourable, while some powders will also offer digestion enzymes that help with absorption and the digestion of protein. Ultimately, the purer the protein form the better when you’re surveying that ingredients list.

What are the best whey protein powders to buy?

Optimum Nutrition Gold Standard 100% Whey

Giving you a blend of all three main types of whey protein, this powder offers 24g of protein and a serving of BCAA (branched-chain amino acids) to offer an additional boost in muscle growth and to reduce fatigue after a tough workout. There are five flavours to choose from, but remember: this is one to sink 30 minutes before a workout or just after your session has been completed. £14.99 for 450g. optimumnutrition.com

USN Blue Lab 100% Whey Premium Protein

Offering 24g of protein per serving, USN uses a blend of isolate, hydrolysate and concentrate whey to quickly release that protein into the body and start putting it to replenishing and recovery work. There’s a total of seven flavours to pick from, which should be ideally consumed after a gym session or any other time of the day you need that whey top-up. £26.25. At amazon.co.uk  

Innermost ‘The Strong’ Protein

Not just a solid choice because the branding will sit prettier in your kitchen cupboards, of Innermost's four signature protein blends, also comprised of The Fit, The Health and The Lean, The Strong is its hardest hitting. Not just a means to fill out freshly-torn biceps with a combined 34g of whey concentrate and isolate, casein to encourage protein absorption and 3g of creatine monohydrate to speed up recovery times, it also incorporates montmorency cherries and magnesium, which serve as an anti-inflammatory, and bilberries for an additional antioxidant hit. £29.95 for 600g. liveinnermost.com

Reflex Nutrition Instant Whey Pro Protein Powder

The flagship high-protein, low-fat powder of Reflex Nutrition, this blend mixes whey concentrates and isolates with milk protein concentrate to a muscle-friendly macro split of 20g of protein, 1.8g of carbs and 0.9g of fat per serving.

Bulk Pro Informed Whey Protein

This whey isolate and concentrate powder offers a purer protein intake than most, with digestive enzymes on board to help break down ingredients and help the body quickly absorb the nutrients to put it to good work.

Bulk Powders has created it in compliance with international competition standards for professional athletes, making it one made for serious trainers. £20.24 for 900g. bulk.com

MyProtein Clear Whey Isolate

MyProtein’s fruitier approach to giving you that protein hit offers 20g of whey hydrolysate per serving.

Whether you go Mojito, pink grapefruit or tropical dragonfruit, you just need to scoop it into your shaker and mix with water after you’ve put your body through the mill in the gym or out on the road. £19.79 for 20 servings. myprotein.com

PHD Diet Whey

PHD uses a blend of whey protein concentrate, milk protein concentrate and soya protein, which works out to 17g of protein per serving. That’s combined with natural ingredients such as flaxseeds and green tea extract to offer a single serving with fewer than 100 calories. Best consumed in a smoothie between meals, it’s a vegetarian-friendly supplement you can pick up in sweet flavours such as banana and white chocolate. £11.99 for 500g. phd.com

Kinetica Whey Protein

It also uses natural flavours and colourings to help make it a little tastier to take down as well. £16 for 480g. maximuscle.com

Optimum Nutrition Gold Standard 100% Whey Review

A great tasting, reasonably priced whey protein supplement with an excellent nutritional profile from an industry-leading company. What more could you ask for?

Like an all-powerful Caesar, Gold Standard 100% Whey bestrides the supplement market like a Colossus.

It is the king of whey protein, towering over swarms of competing brands which lurk jealously in the shadows like Cassius or Brutus.

It is, if Optimum Nutrition’s marketing material is to be believed, the world’s bestselling protein, with literally millions of satisfied customers worldwide.

But does it deserve this status?

Why exactly is it #1?

Upon what meat doth this product feed that it is grown so great?

Gymtalk investigates…

Product overview

Gold Standard Whey has been on the market for a LONG time.

Throughout its reign it has gone through several label iterations, most recently changing from “100% Whey” to “Gold Standard 100% Whey”.

During this time, the product and Optimum Nutrition have remained one of the industry’s most respected brands, amassing a loyal legion of customers.

Looking at the nutritional profile of this product, you can begin to see why.

Gold Standard 100% Whey comprises three different forms of whey protein: whey protein isolate, whey protein concentrate, and whey peptides.

It also contains amino acids (enzymes to help break down the protein), including three of the most valuable BCAAs (Leucine, Isoleucine and Valine), in addition to other muscle-building goodies such as glutamine.  

Per scoop we’re looking at 24g of protein, 1g of fat, 3g carbs, and 120 calories.

This nutritional make-up makes it ideal for a protein injection between meals, before bed or as a post-workout fix.

Remember, Gold Standard 100% Whey is not a mass gainer or a a meal replacement; it should be used to complement your meals and help you reach your required daily level of protein.

Taste and texture

Gold Standard 100% Whey comes in 16 different flavours.

Most of these are nothing to write home about.

Coffee and Chocolate Malt are pretty decent – but avoid Vanilla at all costs.

It’s atrocious and enough to put you off trying anything vanilla-flavoured ever again.

The powder dissolves quickly with little shaking, which means mixing your shake won’t leave your wrist feeling like a 13 year old kid who’s just discovered Red Tube.

I experienced no clumps, although there was a little bit of froth.

It also digested like a dream, meaning I was able to catch the Tube to work each day without having to constantly clench my arse cheeks for fear of dropping some kind of methane Nagasaki on my fellow commuters.

Effectiveness

I opted to use Gold Standard 100% Whey after coming off a bulking cycle in order to tone up while maintaining muscle mass.

During my first month of using this supplement I had protein shakes first thing in the morning and after every workout.

Remarkably, despite increased cardio (I was running about 15 miles a week) and a lower daily calorie intake, I still managed to gain a few pounds of muscle mass.

This took me very much by surprise as I was definitely expecting to lose a little weight.

What’s more, recovery was fantastic.

I was able to push myself to the limit on every workout without feeling like I’d been gang-wedgied by a pissed-up uni rugby team the next day.

Value for money

You can usually pick up 5lbs of Gold Standard 100% Whey for around £45 / $50 by shopping here at Amazon .

Although this is slightly more expensive than some of the other bargain basement brands, bear in mind this supplement contains whey protein isolate (pure protein) as its primary ingredient in addition to lots of other goodies that you would normally find yourself paying extra for.

For this kind of quality you can’t go far wrong with this price tag.

A great tasting, reasonably priced whey protein supplement with an excellent nutritional profile from an industry leading company.

What more could you ask for?

Indubitably, its accolades are well and truly deserved, and the quality of this product speaks for itself.

Just take a look at the simple branding – no gimmicks or bullshit, just pure awesome ingredients.

Nice review Henry although it’s £56.64 not £29.38 on ON Academy for 2.27kg so quite a bit more expensive than bulk UK suppliers.

You’re absolutely right – I did think that was very cheap indeed!

Review updated.

Still good value for the ingredients you get IMO.

Nice review.

I am a huge fan of most of ON’s products with their Gold Whey probably being my favorite, and most used, of their supplements.

Sadly, I actually use the Vanilla every once in a while. I

t is not exactly good, but I can tolerate it.

Love the chocolate flavors.

Even ON’s casein tastes good.

Drinking a couple scoops of it right now actually mixed with water.

Hi Mike, thanks for stopping by.

This was the first ON supplement that I tried but I can see why it’s so popular.

What other products of theirs would you recommend?

Great review Henry, if I take this product, will I make alllll kiiinds of gains?

If you’re eating clean and training hard, I would be surprised if you didn’t!

I actually am a really big fan of ON Whey, I like the taste and texture and it has the best value for money in terms of scoops for weight.

The only bad thing is that the overall product is quite pricey.

Yeah, it’s by no means the cheapest, but the quality is unmatched.

Made me think about the fact that choosing the right protein powder isn’t just a decision made for yourself and your workout results but it can also be a social decision in a way.

Not molesting your fellow commuters in the subway with your supplement induced flatulence really should be something to consider when making a purchase decision.

Unless, of course, you live somewhere in the mountains of Kyrgyzstan.

But then you’d probably have other problems anyway.

Ok… getting off topic a bit.

What I wanted to say is: I really never understood why most companies don’t offer a version without artificial flavoring with their big sellers.

I personally don’t really need a tropical punch after trying to be a really tough dude in the gym for an hour.

I might want to be able to spice that stuff up with whatever flavor I have in mind and especially be able to choose the amount of flavoring.

Maybe even without artificial sweeteners and all that other crap they cram in there just so that it doesn’t taste like painter’s putty.

But maybe I’m the only one.

But I would think that they would find some customers for that if they were to market that a little better..

Why the hell did write that much in this comment now?!

Could be because it’s leg day today..

Hi Peter, thanks for the comment, enjoyed your ramblings!

There’s plenty of unflavoured supplements on the market – just have a gander at some of the “bargain basement” brands in the UK.

Lol good review

Thanks John!

Can I lose weight if I eat clean and use this product?

This supplement will certainly help you loose body fat and tone up – provided, of course, that you are training hard and eating well.

Hey, just want to know if whey protein increase the muscle mass?

If not, which one do you think is good to increase the muscle mass?

Hi Inzy, thanks for your comment.

Increasing protein consumption via supplements such as Gold Standard 100% Whey will certainly aid muscle repair/recovery.

Provided, of course, that you are training hard and eating healthy nutritious food – otherwise you’ll just be pissing into the breeze.

Let me know if you have any further questions 🙂

This is the best whey protein out there and 9 time protein of the year award winner.

Hi Varinder. I agree – certainly one of the best proteins on the market and full deserving of its multiple awards!

I’ve been working out in a gym, and I just wanna know how many scoops should I use?

I’m using Whey Protein Isolate Gold Standard, I need your suggestions…

Just follow the instructions…

Excellent Review.

What I like about Gold Standard is that it actually consists three whey protein sources.

That makes it one of the best whey Proteins for me 😉

Absolutely!

I’ve just started in the gym and I got 100% Whey.

How many days will it take to see the result?

Impossible question to answer.

Be consistent with your training, diet and supplementation and you will see results within a few months I am sure.

We are big fans of the Gold Standard 100% Whey.

The best protein out there on the market!

Keep going with great content.

Won’t get any argument out of us!

Whey Gold Standard – for weight loss or weight gain?

Whether your goal is to gain muscle mass or loose weight, protein is essential.

So, to answer your question, it can be used to assist with both goals.

If you want to build mass, you need an abundance of protein to promote muscle repair and growth.

If you want to loose weight, protein helps boost your metabolism and will fill you up – preventing you from gorging on rubbish.

And whey protein in particular is great for weight loss as it’s low in calories/fat while good at satisfying your appetite.

A very basic answer there – let me know if you have any further questions.

Sir, by using 100% Optimum Standard Gold Whey can I build muscles?

Supplements should be the very last piece of the puzzle when trying to build muscle.

Before even considering protein shakes, your training routine and overall diet should be on point.

If this is something that you would like help with, feel free to send us an email or contact us on Twitter .

I love whey.

Hey Henry, it’s a pretty good and useful article.

I’m going to start Insanity (Beachbody co) workout, which is very intense.

I was thinking of buying ON and your article made it easy for me to take a decision.

A trainer at a gym told me that even though ON advertises as one scoop has 24g of protein, but it only has 10-12g.

Is that really true?

My earnings are not that great to maintain a great nutrition diet for the insanity workout.

I was just thinking of takin these:

1st meal) 1scoop of ON.

2nd meal) 1 slice of wheat bread with peanut better or yogurt

3rd meal) oatmeal with banana.

4th meal) 1 slice of wheat bread with peanut butter and banana.

5th meal) oatmeal with banana.

I hope it makes sense.

Regarding your first question, certainly not.

While some (very dodgy) brands have been guilty of supplement spiking and other fraudulent practices in the past, Optimum Nutrition are one of the most respected – and best – brands on the market.

Regarding your diet, I would add in some more wholesome, protein-rich foods.

Milk, eggs, nuts, tuna, etc are all very cheap and excellent sources of protein.

For more advice on diet, check out some of our articles on nutrition:

I have two year to join gym but my weight gain has stopped, I also take supplement and I choose whey.

How to gain weight to this supplement?

Eat lots of protein and perform the following exercises several times per week: squat, bench, deadlift.

It’s really that simple.

Choosing a supplement to assist in a bulking diet.

Mass gainers are quite expensive but bulk buying this is relatively cheap.

Along with a wholesome diet and compound exercises at the gym would this be satisfactory to add to a shake and use post workout?

Or should I find something else (currently on about 5000 calorie diet)?

Gold Standard Whey will be fine – just make sure you are supplementing and not replacing any meals.

I’m working on losing fat/toning more.

Is this protein good for women as well?

I need a good meal replacement.

I have used other brands but have wanted to give this a try for a while and haven’t met any women who use this kind.

Also, best flavor to mix with water?

Hi Cheyenne, yes, supplementing your diet with a protein shake will definitely help with fat loss, regardless of sex.

However, Gold Standard Whey is a protein supplement, not an MRP, so it should be taken between meals and post-workout to help you get a sufficient amount of protein throughout the day.

For me the best flavours are the chocolate ones – you can never go wrong with chocolate!

Let me know if you have any more questions 🙂

Is Optimum Nutrition whey protein isolate helpful for the skinny guys to gain muscles and get bulky?

Yes it will help with your goals – provided you are already training and eating well.

For more help, check out our training and nutrition articles:

http://www.gym-talk.com/training/

Can you please tell me about the flavour ‘Rocky Road’?

I haven’t tried it, sorry, but if the other ON flavours are anything to go by, I’m sure it’ll be delicious!

Far out I love Gold Standard Whey.

Such an awesome product with such amazing flavours.

I usually buy mine from Fitmonk in Australia or Bodybuilding.com when I travel to the States.

Thanks for the comment 🙂

Hey, your review was good but I have to ask that does it help in building some muscles?

Yes, supplementing your diet with protein will aid with muscle recovery/growth, provided you are training right, eating right, and getting enough rest/sleep.

Hey Henry that was a detailed review.

Could you please help me out with my questions?

So I have started hitting the gym after a long time.

I wish to have a nice lean body with a little bit of size gain but don’t want to be bulky.

Can ON WHEY do that for me?

My trainer said if I take one scoop with milk after workout and one again at night, I will see results.

Your opinions on this?

Yes, it will help with your goals, take it between meals and, where convenient, as a hit of protein post-workout.

Just remember that supplements are a small piece of the puzzle and they’re certainly not a magic fix.

The biggest changes in your body composition/strength will come from training and eating correctly.

Which time will best to use this product?

Post-workout then at any other time during the day to boost daily protein intake.

I see I am an odd duck here but I would like to know what Gold Standard Whey Protein will do for me.

I am a 65 year old female diagnosed with osteoporosis 5 years ago.

All supplements and exercise are geared to increasing bone density.

I take 1 scoop a day mixed with 1 scoop of Neo Cell collagen.

Will the whey help me ?????

Please consult your doctor, they’ll be in a much better position to advise.

When and how many shakes should get per day?

And can you recommend a good flavor without chocolate?

As many as you need to hit your daily protein goals, which should be around 1 to 1.5g per pound of body weight.

Flavour-wise, Caramel Toffee Fudge and Banana Cream are both delicious.

How much water should I drink if I use this product?

Your daily water intake should be around 1 litre per every 1,000 kcal you expend.

So if you expend approx 4,000 kcal per day, you should be consuming 4 litres of water.

If you’re getting enough, your urine should be colourless and odourless.

I want to gain only muscles which protein should I prefer?

A simple whey shake like this with low carb/sugar/calorie content will be fine.

I have been in the gym for quite some time now, been working out so hard, as I would love to be ripped.

So a friend of mine suggested Whey Isolate.

After couples of weeks I realized that I’m loosing too many weight.

Any Advice?

As I want to get ripped but at same time gain as many muscles in a ripped manner!!!

Hi Kedrick, thanks for stopping by.

If you are supplementing your existing diet with this shake – and not replacing meals – as well as lifting weights then you should certainly be building muscle and not losing weight.

Diet-wise, focus on eating healthy, high-protein meals with lots of veggies and drinking lots of water.

Don’t overdo it on the carbs, focus on high-protein, high-fat, as advised by the caveman diet etc.

In the gym, work out with full body routines (such as 5×5) three times per week, leaving lots of time for adequate rest and recovery.

If your goal is to get ripped, then you’ll also need to include some high-intensity cardio (boxing is great) a few times per week to expedite fat loss.

Hope that helps as a starting point – do let me know if you need any more guidance.

Would I make gains using this, I do about 6 sets and I’m pretty tired after working out.

I train almost every day.

Yes, supplementing your diet with whey protein will certainly aid muscle gain, provided of course you are training and eating correctly.

Could you please help me with couple of questions?

I am fat and I wanted to lose weight.

If I use this protein shake, does it help me to lose weight?

Supplementing with a protein shake will help your body receive all the protein it needs to build and maintain muscle mass.

However, supplements are a small part of the puzzle – you, of course, need to be eating well and exercising as a basis to losing weight.

So, simply, yes, protein shakes can help, but they shouldn’t be your first port of call.

In how much time it will give result?

Impossible to tell as there are so many factors at play.

The key is to not go looking for shortcuts or answers in supplements – this is a long-term game.

Be consistent with your diet and training over months and years and you will definitely see results.

Sir I am 121 lbs and a skinny guy.

Will whey protein isolate or ON Serious Mass help to gain mass and weight?

I would like to bulk up.

My body was in good shape.

Yes, it will certainly help, but you need to firstly focus on getting your training and diet right.

I just need to know how much whey protein to help me to increase my muscles?

I eat a lot right now, I have 15 inch biceps, after whey protein will it increase?

Aim to consume around 1-1.5g of protein per lb of bodyweight per day.

Most of this should come from real food sources such as meat, fish, nuts etc but use a protein shake between meals to help you reach this goal.

I am 18 year old skinny boy, my height is 6’1 and my weight is 66 kg.

I’ve had a lot of supplements but they have not given me any results, so my question is will ON whey protein will help me to gain weight?

If you’re not making any gains, I would advise that you stop looking for answers in supplements, as they are only a very small piece of the puzzle.

Instead, make sure your workout routine and diet is more conducive to results.

I would suggest starting with a decent full-body routine such as Stronglifts 5×5 and making sure you’re getting plenty of wholesome high-protein food in your diet with lots of healthy fats.

Hi, I am 18 years old and my weight is 100 lb.

How many lb protein requires to growth 170 lb of whey gold?

As a guideline, I would suggest consuming around 1 to 1.5 grams of protein per pound of bodyweight per day.

Consume however much whey protein you need to help you hit that daily target, but focus on getting as much protein as you can from wholesome food sources.

Hi, I’m 28 years old, female.

Need some help in finding a good protein shake.

I have been taking PHD Diet for a while now but after I keep reading all the good reviews about Gold 100%, thinking to switch over.

I am on my diet plan so need a very good supplement to replace my meal.

I am trying to lose some fat and tone up my body.

I do gym 5 days a week.

Can you suggest me a better one with good flavor??

I’d definitely recommend Gold Standard if you have the budget for it.

I’ve got the Rocky Road flavour at the moment which is delicious, and I’d also recommend the Cookies & Cream.

Dear Henry, I do workout at home, my body is lean, and I have low-fat body.

I am using Whey Protein Gold, please give me tips to gain some weight as well.

Use it as a supplement between means to help you increase your daily protein intake.

As a guide you want to be hitting between 1 to 1.5g of protein per pound of bodyweight per day.

As far as workouts go, I’d recommend a three-day-per-week full-body routine.

We have written about plenty here .

Hi, we tried whey protein gold standard and all we can say is it’s simply awesome and the results were pleasing.

We tried it for 1 month and we were able to gain lean muscle mass.

Great to hear!

Does Whey Gold Standard contain nuts?

I wouldn’t have thought so – but to err on the side of caution I would suggesting contacting their customer service.

My Goal is to reduce fat/weight and get lean muscles.

Is this product good enough for that?

Yes, it will help, provided you are training hard, eating healthily and giving your body adequate rest/sleep.

Hi, I want to lose my weight.

Could you suggest to me if this ON product is good enough for me to lose the weight?

Or if any other product is best for the same goal?

If you want to lose weight, I wouldn’t suggest a protein supplement.

Save yourself some money and just focus on reducing your calorie intake and getting some exercise.

Hello there, Henry!

Nice, well organized article!

Regarding using Gold Standard 100% Whey to gain mass, I do have several questions that I would like you to answer.

What training routine should I go for for better results?

Should I opt for the 5×5 Reg Park’s training routine?

Or should I go for any other intense training routine?

Waiting for your response, Mr. Henry

For beginners, I would always recommend a routine which prioritises strength development, as heavy compound lifting is the best way to build muscle, bar none.

5×5 is a great place to start – do some further reading on all of the variations out there (Reg Park, Stronglifts, Madcow).

I’d also recommend finding a copy of “Staring Strength” by Mark Rippetoe, which you should be able to pick up from Amazon fairly easily.

Really enjoyed reading this review found it quite funny “methane Nagasaki on my fellow commuters.”

I have just purchased the strawberry flavour and I’m enjoying it very much.

Thanks Henry, come back and let us know how you get on!

This is a good protein… and for a long time had a good price… but now Myprotein impact whey came out… AND IT OFFERS THE SAME QUALITY for a lot less.

Optimum Nutrition 100% Whey Gold Standard Review (2024): Popular for a Reason

By Amanda Capritto, CPT, CES, CNC, CF-L1, CSNC

Expert Verified by Frieda Johnson, NASM-CNC, ISSA-SET

updated May 22, 2024

We test and review fitness products based on an independent, multi-point methodology. If you use our links to purchase something, we may earn a commission. Read our disclosures.

Optimum Nutrition is a ubiquitous supplement brand of which you can find products on the shelves of many major retailers, virtually and IRL. Walk into any GNC or The Vitamin Shoppe and you’re sure to find multiple flavors of Optimum Nutrition protein powder. There’s no shortage of the stuff on Amazon or elsewhere online, either. 

When a product is so ubiquitous, it must be good, right? 

That’s not always the case (unfortunately), but you’ll find out in our Optimum Nutrition 100% Whey Gold Standard Review that it is true for this protein powder. Ahead, learn everything you should know before buying Optimum Nutrition whey, including some of our staff’s top flavor picks. 

Medical disclaimer: This article is intended for educational and informational purposes only. It is not intended as a substitute for medical advice. For health advice, contact a licensed healthcare provider. GGR also recommends choosing a product that has been third-party tested for quality.

5 Optimum Nutrition Flavors Rated

Our product testing team has tried several flavors of Optimum Nutrition Gold Standard Whey Protein Powder, with five ultimately earning a spot on our guide to the best Optimum Nutrition flavors . Some members of our testing team, myself included, have been using this protein powder for the better part of a decade. Additionally, we’re a team of certified personal trainers and nutrition coaches who can help you decipher supplement labels and understand if a product is the right fit for your goals. 

Optimum Nutrition 100% Whey Gold Standard

Optimum Nutrition Gold Standard 100% Whey

Product Highlights

• Contains 3 different kinds of whey protein
• Tested for banned substances
• Over 5 g of BCAAs per serving
• Instantized to help prevent clumping

Pros & Cons

• High in protein
• Plenty of flavor options
• Low in carbs
• Some users say it's overly sweet
• Contains artificial flavors
• Most flavors contain sucralose

Bottom Line

Optimum Nutrition Gold Standard 100% Whey is a team favorite for its budget-friendly prices and taste. Our team has tried multiple Optimum Nutrition flavors, and every one is ranked a 4 or 5 out of 5.

• A Quick Look at Optimum Nutrition 100% Gold Standard Whey

Optimum Nutrition 100% Gold Standard Whey Protein Powder, affectionately shortened to “ON Gold Standard Whey” among fitness enthusiasts, is a high-quality protein supplement that comes in many different flavors. It’s a relatively budget-friendly option, which means it’s not the cleanest, highest-quality protein shake available. 

However, due to its great macro profile—which includes 24 grams of protein per serving—and the great taste in a multitude of flavors, ON Gold Standard Whey appears on all of our protein guides (except for vegan and organic proteins):

• Best whey protein
• Best-tasting protein powder
• Best protein powder for weight loss
• Best protein powder for women
• Best protein powder for men
• Best protein powder overall

Before You Buy

• There are many, many flavors! My personal favorite is the Double Rich Chocolate flavor, and it’s been a staple in my home for many years. Other members of our team love other various flavors; it’s worth exploring before committing.
• The price per serving decreases as the size of the container increases. Buy in bulk and save some cash (as long as you’re sure about the flavor first).
• ON Gold Standard protein does contain artificial flavors and artificial sweeteners , including acesulfame potassium and, in some flavors, sucralose. 
• Is Optimum Nutrition 100% Gold Standard Whey Worth It?

I think Optimum Nutrition Gold Standard Whey is one of the best protein powder options currently on the market. The value proposition is fantastic: 24 grams of protein, only 3 to 4 grams of carbohydrates, and minimal ingredients for a good price. 

Of course, it’s no grass-fed, organic, sustainably sourced protein blend like you get with products from Transparent Labs and XWERKS. But you’re paying far less than $2 per serving. And this protein will help you build muscle mass and assist with muscle recovery just as well as those more expensive brands. 

In other words, for bodybuilding on a budget, yes, Optimum Nutrition whey protein is worth it. 

• People looking for a decent protein source on a budget
• Exercisers who want a high-protein, tasty post-workout shake
• Anyone looking to increase their protein intake in a convenient way

Not recommended for:

• People who wish to steer clear of artificial sweeteners
• Those who follow a vegan diet
• Anyone who’d rather consume a grass-fed protein powder

• Optimum Nutrition 100% Gold Standard Whey Specs
• Experience Using Optimum Nutrition 100% Gold Standard Whey

Optimum Nutrition was, for me, one of the very first supplement brands I reached for when I first started getting into fitness circa 2014. Today, it still makes a regular appearance in my pantry. 

These days, Optimum Nutrition whey protein is my go-to when I need a trusty friend in the form of a high-protein beverage. I know I can count on solid flavor and that I won’t be dealing with any grit or chunks. I know I can mix it with water or milk or almond milk, and it’ll be fine regardless. 

I’ve tasted many flavors and continue to return to Double Rich Chocolate, although I dig Strawberries & Cream, as well. 

• Price Per Serving

The price per serving varies depending on what size container you buy. Some flavors have size options ranging up to 149 servings. For the largest containers, the price hovers around $1.10 per serving, although it can change even more depending on where you buy it. Often, you’ll find the best deals on Amazon.

• Formulation

Optimum Nutrition whey protein is a protein blend that consists of whey protein isolate, whey protein concentrate, and hydrolyzed whey peptides. Each serving contains 5.5 grams of branched-chain amino acids.

It’s low-carb, with just 3 to 4 grams per serving depending on the flavor you choose. The fat content is almost negligible, with a mere 0.5 to 1 gram per serving, again dependent on flavor. 

People who are lactose intolerant will be happy to know that the whey isolate in this protein powder is heavily filtered, meaning excess lactose has been removed. If you tend to have intense digestive issues, you may still want to mix it with milk that contains lactase enzymes to further help break down the milk-derived proteins.

Optimum Nutrition whey is also gluten-free. 

• Taste and Solubility 

One of the most appealing things about ON whey protein is the flavor lineup. There are so many that there’s no way you won’t find one you like. 

The full lineup includes: 

• Banana Cream
• Chocolate Coconut
• Chocolate Hazelnut
• Chocolate Malt
• Chocolate Mint
• Chocolate Peanut Butter
• Cookies & Cream
• Delicious Strawberry
• Double Rich Chocolate
• Extreme Milk Chocolate 
• French Vanilla Creme
• Mocha Cappuccino 
• Strawberries & Cream
• Strawberry Banana
• Vanilla Ice Cream
• White Chocolate 

I’ve already told you my favorite—Double Rich Chocolate—but I also really like the Strawberries & Cream (tastes like strawberry milk) and Mocha Cappuccino. 

In addition to a great taste, ON protein also has great mixability. This is probably partially due to the inclusion of soy lecithin, a common (and, yes, safe) food additive used as an emulsifier. Emulsifiers in food help keep textures smooth and rich. 

But the protein powder is also instantized, which means the powder mixes quickly and easily with a basic shaker bottle, or even in a cup with a spoon. (I don’t recommend the latter, though, just to be sure you don’t get any chunks or floaties). 

• Side Effects

I’ve never experienced any side effects after consuming this protein powder in nearly 10 years of drinking it. None of our other product testers warn about side effects, either. 

In general, whey protein powder is considered safe for consumption. If you have allergies or food intolerances, it’s up to you to read ingredients labels to make sure a product is safe to consume. 

Some people may experience bloating or cramping after consuming protein powder if they are new to it. As your body adjusts and gets used to consuming a large amount of protein at one time, those side effects should go away. If they don’t, it’s best to switch products or talk to your doctor. 

• Third-Party Testing 

According to the website, Optimum Nutrition 100% Gold Standard Whey Protein Powder is tested for banned substances by Informed Choice, one of the best supplement third-party testing companies. 

• Optimum Nutrition 100% Gold Standard Whey vs Dymatize ISO 100

Dymatize ISO 100 Protein Powder

Dymatize ISO 100

• Each serving contains 25 g of whey protein isolate  
• Pre-hydrolyzed protein to speed up absorption
• Available in 11 flavors, including Dunkin’ coffee flavors
• Low in both fat and carbohydrates
• 11 flavor options
• Includes 5.5 grams of BCAAs
• Fast absorption
• Flavors are highly rated
• Complaints of quantity in container
• Contains sucralose and stevia

Available in 11 different flavors, Dymatize ISO100 is stacked with 25 grams of protein, including 5.5 grams of BCAAs and 4.4 grams of glutamine designed to enhance muscular growth and recovery.

Dymatize ISO 100 is often compared to Optimum Nutrition 100% Gold Standard Whey since they have a similar price point and macro profile. ISO 100 is also available through many retailers just like ON. 

Here’s a quick comparison of the two. As you’ll notice, one of the main differences between them is that the Dymatize does not contain any whey protein concentrate, only isolate. 

• Customer Experience 

I’ve been using Optimum Nutrition products for nearly a decade and I’ve never had an issue with customer satisfaction. Granted, I usually pop over to my local GNC to buy my supplements, but I also haven’t heard any major complaints about the brand from other customers. 

When it comes to ON, your experience will largely be dictated by the retailer you purchase through. 

• Ordering Optimum Nutrition 100% Gold Standard Whey 

You can order Optimum Nutrition whey protein powder directly from optimumnutrition.com or online via Amazon, Walmart, GNC, The Vitamin Shoppe, and Costco. It’s likely available in-person at your local supplements store, too. 

On Amazon, it arrives quickly and free from shipping charges with Amazon Prime.

• Customer Reviews

Customers are generally pleased with Optimum Nutrition 100% Gold Standard Whey Protein Powder. At the time of writing, this protein powder has an average rating of 4.7 out of 5 stars on Amazon with more than 131,000 (!) whey protein reviews. 

The vast majority of reviewers say the flavors are good, as is the texture. 

One longtime buyer wrote : 

“I’ve been buying Optimum Nutrition Gold Standard whey protein powder double chocolate flavor for probably 8 years now and finally leaving a review.

• Dissolves very easily in water or milk, and goes great in a smoothie, too.
• Doesn’t have the chalky taste or texture of some other whey powders. People who complain about the flavor are being way too picky. The double chocolate is totally fine. Not as good as a real chocolate shake obviously but also not unpleasant in the least. It’s protein powder…what do you expect? I haven’t bothered to try any of the other flavors so I can’t comment on that.
• The 5 lb bucket is a great value, compromising between economy of scale and not taking up my entire kitchen cabinet.
• Long shelf life.
• Gainz. Obviously.

Cons: None that I can think of, unless you are a vegan.”

I must say: I’m hurt that one reviewer wrote “ Double Chocolate is horrible ” since that’s my favorite flavor, but to each his own, I suppose. This reviewer still left a 5-star review, stating that the Rocky Road flavor resulted in forgiveness.

Some reviews indicate problems with quality assurance. One buyer wrote that they’d been buying this protein powder in 2-pound tubs for a while and decided to buy a 5-pound tub for a lower cost per serving. They were disappointed when the protein didn’t smell or taste right, though, and got a refund. 

• Final Verdict of Our Optimum Nutrition 100% Gold Standard Whey Review

Optimum Nutrition 100% Gold Standard Whey is a solid protein supplement with a strong macro profile. It’s not the “cleanest” protein powder available, but it costs less than many brands, making it more accessible to the average consumer. 

• ON whey protein is available in nearly 20 flavors 
• Its formula contains a blend of whey isolate and concentrate, and hydrolyzed whey 
• Each serving contains 24 grams of protein and 5.5 grams of BCAAs

• Optimum Nutrition 100% Gold Standard Whey FAQs

Is Optimum Nutrition protein powder good? 

Optimum Nutrition whey protein comes in many flavors, so it’s unlikely that there’s not at least one you’ll like. Our product testers enjoy many flavors and like to drink it plain or mixed with smoothies. 

Is protein powder good for you? 

Protein powder can be a great way to hit protein intake goals. It’s not inherently good or bad for you; it depends on your dietary preferences and needs. Those who follow specific diets, such as vegan or keto, or have dietary restrictions for health reasons, should take care to read ingredients labels.

Is whey protein isolate better than whey concentrate?

The main difference between these two types of proteins is that whey isolate undergoes a more extensive filtration process than concentrate. Thus, it tends to cost more, but it contains fewer fats and carbohydrates. People who closely monitor their macronutrients may wish to opt for isolate over concentrate.

Optimum Nutrition Whey Isolate vs Gold Standard: What's best?

As you have probably already discovered if you are reading this article, not all whey proteins were created equal. Whey protein encompasses all protein powders that contain the ‘whey’ part of milk, after it has been separated from casein (another dairy-based protein supplement). Within the realm of whey proteins, there are several versions available. These include concentrate and isolate. Optimum Nutrition offer options for both under the names ‘ Gold Standard Whey ’ and ‘ Gold Standard Isolate ’.

100% Whey Gold Standard vs Pure Whey Protein Isolate: which is the best whey?

Both Gold Standard Whey and Gold Standard Isolate are incredible products that can have their place in a muscle building or fat loss diet. Both being whey products, you can expect many of the same benefits including them being complete proteins. By this, we mean that all reputable whey protein powders contain the full spectrum of 9 essential amino acids, including the branched chain amino acids, or BCAAs (leucine, isoleucine and valine). In this regard, whey is superior to something like a pea protein which will need to be combined with another complimentary source of protein in the same meal to make it 'complete'. If your goal is to build maximum muscle mass, an awareness of the quality of the proteins you consume is a must!

Next, both have great mixability. You might have experienced protein powders in the past that remain lumpy and powdery no matter how hard you try to blend them - not Optimum Nutrition! You can guarantee that their wheys will easily mix with cold water into a perfect form. You can expect a slightly thicker shake with a concentrate, due to the small amount of fat.

Whey proteins are also versatile and easy to stack. If you are new to using supplements, a quality protein powder is probably one of the first things we'd advise picking up, for convenience if nothing else! Alongside your whey protein concentrate or isolate, you could use a number of other basic supplements from creatine to pre-workout to BCAAs.

So, what are the differences?

Optimum Nutrition Gold Standard Isolate vs Whey Protein ingredient comparison table

Both proteins contain impressive ingredients lists, boasting around 25 grams of protein respectively and being gluten-free. The whey isolate protein has 0 gram of fat and uses the highest quality whey, whereas the concentrate contains added digestive enzymes a little more gram of carbohydrates, though still coming in at less than 2g per serving.

*Nutrition Information may vary depending on flavour. Table based on Chocolate flavours.

ON Whey Isolate vs Gold Standard for flavour

Being the more widely popular and recognised product, Optimum do offer more flavours in Gold Standard Whey , including some fun ones such as Caramel Toffee Fudge and Chocolate & Hazelnut! In the Isolate, we see the more ‘classic’ flavours like Vanilla, Strawberry and Chocolate flavor. Whatever you go for, ON are known for doing a great job with their flavouring systems as we’ve seen in products like Amino Energy.

Both protein powders get their taste from sucralose as sweetener and flavourings (both natural and artificial flavors are used in gold standard 100% isolate). This is pretty typical for a whey product and, in our experience, results in a more authentic taste than protein powders that use something like stevia, a natural alternative that can leave a not

Our advice: looking for a quick shake? Go for isolate. Want something to flavour your oats? The fun flavours and thicker consistency of Gold Standard Whey will take them to a whole new level.

Other differences between Optimum Nutrition Whey and Isolate

1. protein content.

One of the key differences between a whey concentrate and isolate is that the protein yield is higher in and isolate due to the processes used to prepare it. A typical whey concentrate will be made up of 80% protein, with the remaining calories from carbs and fat, whereas an isolate has undergone further processing to produce at least 90% yield of ultra-pure protein. For those on a very low carb diet, choosing an isolate can save a few of those precious macros to use elsewhere.

For something even 'cleaner', Optimum Nutrition Platinum Hydro Whey breaks whey isolate down further for ultra fast absorption and the purest protein supplement you can buy.

2. Digestion

Another benefit of whey protein isolate over concentrate is that is is more readily digested due to containing 0g fat, 1g of carbohydrates and being lactose free. If you had been considering a vegan protein powder because concentrates do not sit well with you, the solution might lie in opting for a whey isolate - it is also worth noting that you probably won't find a vegan protein with such impressive macros!

The fast digesting nature of isolate makes it the optimal choice around workouts when you want a quick supply of amino acids delivering to the muscles with as little digestive distress as possible. Add to ground rice or simply mix with a carb powder like highly branched cyclic dextrin for a perfect post-workout recovery meal!

At other times of the day, such as before bed, a slower releasing protein like a concentrate, casein or blend might be preferable to give a slower release of those valuable aminos, including the 3 BCAAs, through hours in what is essentially a fasted state.

Assuming that you don't mind a couple of grams of carbs and fats in your protein, and you've never had any GI issues with dairy, a huge positive of opting for a concentrate is the fact that they come at a lower cost per serving.

If you are just entering into the world of protein supplements, it is wise to start out with an affordable whey concentrate to first see how you like the supplement and how you get on. This means that you can experiment with different flavours and ways of serving up your whey (no pun intended) to find the perfect powder for you.

With Optimum Nutrition, you can trust that supplements are of a high quality no matter what. The brand have been leading the sports nutrition industry for many years, and you can trust that they are producing some of the best protein powders you can buy.

Optimum Nutrition Whey Protein Isolate vs Gold Standard Whey: Conclusion

Ultimately, both whey protein isolate and concentrate have value in helping you reach your daily protein targets and being a source of amino acids including BCAAs and glutamine. Incorporating a protein shake into your diet is a great way to stay satiated, save money on more expensive sources of protein such as lean meat and fish, and spike muscle protein synthesis for greater gains in lean muscle and recovery.

Whey isolate might be the better choice if looking for something fast digesting, if unable to consume high amounts of lactose or if on a diet with very limited total fats and carbohydrates.

Whey concentrate could be the better option if looking for a more 'milkshake' like taste and consistency and to be more cost effective.

After the US and UK, India is the third-ever region to manufacture Optimum Nutrition products. To match the ever-increasing demand in the Indian subcontinent we have now partnered up with Tirupati Lifesciences and started locally manufacturing some of our key products such as Gold Standard 100% Whey (Double Rich Chocolate, Vanilla Ice Cream), Serious Mass, and Performance Whey at Paonta Sahib. A major portion of our products and lot of your favorite Gold Standard flavors are still made in the USA. We are planning to increase our local manufacturing capacity and going to add more products to locally manfactured portfolio. This allows us to serve you faster and more efficiently. Its a Dynamic process really and for coming few years you will see a mix of USA as well as India manufactured inventory in the market. Where ever the product is manufactured, you can rest assured that it is made with utmost precision and same quality and safety standards that makes ON the #1 selling sports protein powder brand in the world.

It is a blend of whey protein isolate, whey protein concentrate, and hydrolysed whey protein, with the ingredients listed in order of predominance (first ingredient whey protein isolate). Learn more about Gold Standard 100% Whey HERE

It comes from cow's milk

Amino Acids are building blocks of proteins. They are naturally present in all proteins. The amino acids in our protein supplements are naturally occuring from the whey protein itself. We do not add additional amino acids to the products.

This is a proprietary information. However, please keep in mind the ingredients are listed in order of predominance. For example, Gold Standard 100% Whey has Whey Protein Isolate listed as the first protein on the ingredient list which means it is the primary source of protein in the blend.  

The main advantage of Gold Standard Isolate is that it is 100% isolate compared to Gold Standard Whey which is a blend of whey protein isolate (WPI), whey protein concentrate (WPC), and Hydrolysed Whey. Therefore GS Isolate has a higher percentage of protein and a lower level of carbohydrate, lactose and fat per serving. Gold Standard Isolate has 25g of protein per serving whereas GS Whey has 24g per serving, so depending on how much protein you need daily or whether or not you mind little more of carbohydrates, fats and calories in your diet, you may prefer to choose one over the other. However, both protein powders support muscle recovery and rebuilding, when taken over time with regular resistance training.

Optimum Nutrition protein products including  Gold Standard 100% Whey contain complete high quality protein sources. This means that they contain all 20 amino acids - which are divided into essential (not produced by the body and are required from food in the diet) and non essential (produced by the body and not needed from food in the diet) amino acids.   It is well understood though that a complete protein with all 20 amino acids is needed to support muscle. 

It is naturally occuring so a range of about 90-110 mg per serving

It is naturally occuring so a range of approximately 240-260 mg per serving

All the whey used in our products is sourced from cow’s milk.

Alcohol is not added or used at any stage during production of our proteins and powders.

No, the proteins that we use in our products are made  using either synthetic or fungally derived rennet.

What you are seeing is completely normal. Not all ingredients are the same level of granulation or precipitation of free-form amino acids, so at times and depending on how well mixed, there can be some visible fall-out. You can continue with your method of mixing to make it a bit more homogenous. Hope that helps!

 The coffee flavors that do contain caffeine will list the amount on the back panel (Coffee and Mocha Cappuccino). We do not add any synthetic anhydrous caffeine in GS Whey.

No, it is a synthetic product, Hydroxyl Acetonitrite Methylamine, with no animal ingredients

The bloating effect caused by creatine is due to water retention and is an individual response.

It is derived from the fermentation of glucose. This is a soy free product.

The soy lecithin is a part of the initial blend of BCAA which we use to make up the amino energy product so the amounts in the product are at trace levels. It is added to the product to allow the product to be better dispersed/mixed when liquid is added.

It is derived from Corn.

Optimum Nutrition Gold Standard vs Isolate: Which is right for you?

For many people just starting out or getting back into building muscle, protein powders are the number one choice supplement to increase results. A huge range of different protein powder blends is now available including casein and vegan formulations.

During this post, we will be discussing whey protein which is the most popular form of protein powder for consuming after an intense workout. Many well-established brands have multiple whey protein blends available. Today we take a look at Optimum Nutrition Gold Standard vs Isolate to understand which is the one you should purchase.

Whey protein powders are an excellent source of protein and the benefits are widely documented . Increasing muscle growth is the number one reason many of us regularly consume whey protein. During a workout such as weight lifting, muscles are broken down due to the intensity and frequency of resistance training.

After a workout, they are ready to consume protein to begin the process of muscle growth and repair. Protein is the key nutrient for muscles to support increased growth and strength. Whey protein is favoured due to its nature as a fast-digesting protein, allowing it to reach muscles when they need it after exercise.

It also contains the building blocks of muscle as it contains a significant about of Branched-chain amino acids. With so many options available, it’s important to make the right decision on the best supplements for you. We often find that once we try a new brand, we like to test many of their supplements at the same time.

I have regularly used both of these protein powders previously love the quality of both of them. The choice of when I use each depends on my current goals. Find out below which one we recommend for you.

About Optimum Nutrition

For those who have been using supplements for a long time, we are sure you will have come across Optimum Nutrition before. The brand was founded back in 1986, making it one of the very first sports supplement nutrition brands for those looking for supplements to support muscle gain . Fast forward to today and with over 30 years experience, Optimum Nutrition is one of the few sports nutrition companies to manufacture in every product category.

The stand-out feature of all Optimum Nutrition products is their uncompromising quality. This starts by using carefully selected premium raw materials. The state of the art manufacturing plant is also Informed Sport registered to ensure quality and performance. All of this is the reason Gold Standard Whey Protein is the worlds best-selling whey protein powder.

Like most, we were first introduced to Optimum Nutrition through Gold Standard whey, and now regularly use many of the supplements in the range. The large collection includes casein protein, BCAAS, pre-workout and multi-vitamins . One of the big benefits of Optimum Nutrition is the wide availability of the product range.

While many similar popular whey protein products are only available from the manufacturer’s website, Optimum Nutrition products are distributed to a large number of sports nutrition retailers. This ensures you can always find the supplement you are looking for, even when it is not available from your favourite retailer. 

Understanding the Protein

Before we take a deep dive into both of these products, let’s take a look at the different types of whey protein. Not all whey is the same, and different types of whey are the reason for both of these supplements being different.

The most widely available option is whey protein concentrate . This is the type of whey found in the majority of nearly all whey protein supplements. When you see a good value protein powder it is usually always whey concentrate. For most users, this is a great choice, especially when just starting out or looking to build muscle.

Whey concentrate contains a roughly 80% protein content, far higher than any high protein foods. The remaining 20% is made up of carbohydrates and fat. The key benefits include a low cost and wide availability.

A more niche option, but still largely available is whey protein isolate . Where this differs from concentrate is increased protein content. To achieve this, the protein goes through additional processes to produce a higher protein concentration with fewer carbohydrates and fat.

These increased processes and purity result in a higher cost and many users are not willing to pay a premium. For many, the slight increase in protein is not worth the often substantial price increase with a full whey isolate supplement.

Gold Standard

This protein powder contains a blend of mostly whey isolate with some whey concentrate. This allows it to achieve many of the benefits of both. Each serving contains a huge 24g of protein which is superior compared to most other protein shakes available today. There is also a relatively low 1.2g of sugars and 1.6g of carbs.

These stats are one of the main reasons for the popularity of Gold Standard as it can often be hard to beat without spending significantly more.  In comparison, MyProtein Impact Whey contains 21g of protein with each serving. The nutrient profile also contains 5.5g of BCAAs in each serving and 4g of glutamine and glutamine acid.

In our opinion, this is perfectly fine for the majority of gym-goers and already higher than the nutritional value which can be found in many whey protein supplements.

100% Isolate

Now, let’s take Gold standard and turn it up to the next level. Whereas Gold Standard is made up of a blend of both concentrate and isolate whey, 100% isolate uses solely isolate whey protein. This results in an ultra-pure whey protein supplement with little room for carbohydrates or fat.

Each serving contains an industry-leading 25g of whey protein. At the same time, there is just 0.4g of fat and 0.3g of sugar. This nutritional value makes 100% isolate ideal for those on a very strict cutting diet that need to meet tight macro goals for both fat and carbohydrates. Alternatively, it is a great option for those looking to maximise their protein consumed in every serving.

Where this product goes a step further is by the whey isolate also being hydrolyzed. With hydrolyzed whey, the protein has been pre-digested so that it can be absorbed faster and also causes a greater spike in insulin levels. Ideal for those looking to get protein digested and reaching muscles as fast as possible. 

The overall nutritional values of both supplements are great and far superior to most products on the market. Gold Standard is great for most of us and provides little to be disappointed with. However, 100% isolate takes nutrition to the absolute limits by providing superior protein content. The hydrolyzed isolates ensure that protein is digested quickly to get to muscles when they need it. 

Taste & flavours

When it comes to great taste and flavour, this is one area which Optimum Nutrition do really well across all of their products. We generally find that whey protein supplements often taste good, but some go beyond and really stand out. A great tasting protein shake should not leave a bad taste behind and should also be easy to mix in a protein shaker.

Gold Standard comes in a market-leading amount of flavours, with over 14 to choose from. This is far more than most whey protein supplements provide. The choice of flavours includes common flavours such as chocolate, vanilla and strawberry.

There are also some more unusual flavours to choose from including white chocolate and toffee fudge. Our favourite flavour is mint chocolate, which we find tastes great and Optimum Nutrition do this flavour better than any other supplement manufacturer. Gold Standard mixes easily in a shaker bottle without any issues. 

Optimum Nutrition 100% Isolate comes in a limited amount of flavours. This is common for full whey isolate products as they tend to not be as popular compared with a lower cost whey protein supplement. The flavours include strawberry, vanilla and chocolate.

Our favourite is the chocolate flavour which tastes great and leaves a pleasant taste in the mouth. As you would expect, this supplement mixes perfectly find in a shaker and is easy to consume. As both of these come in a tub, instead of a pouch, they are easy to get out with the included scoop and closing the lid keeps them fresh. 

The full Optimum Nutrition brand of products is a premium range that can often be higher than some supplement manufacturers. The high-quality and great nutritional profile is the reason many of us are prepared to spend more to get Optimum Nutrition products. Luckily, Optimum Nutrition supplements are available from a wide variety of retailers online, which gives the ability to shop around and find the lowest cost.

Gold Standard whey protein retails for £27.99 for a 908g tub on the Optimum Nutrition website. However, it can more commonly be found for around £23 on Amazon and other supplement retailers. In comparison, a 1kg pouch of MyProtein Impact Whey costs £21.

Considering that this does contain a blend which includes whey isolates, we find it to be reasonably good value. For those fussy about flavours, or looking to get a high-quality blend which includes whey isolates, this is definitely a great choice.

100% Isolate is slightly more expensive and retails for £28.99 on the Optimum Nutrition website. Unfortunately, it is not available for less elsewhere and sometimes costs more. Retailers including Amazon also sell this for £28.99.

As whey protein is consumed regularly, the cost can soon become noticeable, even with just a slight increase. When compared with whey isolate products from competitors, the price is similar and so it is definitely not overpriced. Bulk Powders whey isolate is also priced at £28.99 for 1kg.

Winner: Gold Standard

Overall it can be difficult to distinguish Optimum Nutrition Gold Standard vs Isolate to decide which is best for you. Whey protein is the ideal supplement to consume after an intense workout to support muscle growth and provide the building blocks of muscle. While most whey protein supplements only use whey concentrate, both of these Optimum Nutrition products contain whey Isolates which contain a higher protein content, with fewer carbohydrates and fat. 

For most users, Gold Standard Whey is the best option. Gold Standard provides the perfect balance between high-quality protein, price and availability. 24g of protein per serving is higher than many protein powders and the unique blend results in the benefits of both whey concentrate and isolate in a single supplement.

The large choice of flavours is also geat benefit for those who are fussy with the taste or regularly like to try different flavours. For those looking for the most superior quality whey protein supplement, with less regard for price or flavours, 100% Isolate is the standout option. For those on a very strict macro diet or looking for a hydrolyzed whey, this also makes a good choice.

Ultimate Nutrition Prostar 100 Whey Protein vs ON Gold Standard — A Close Call

Optimum Nutrition is a brand that’s so well-known it almost needs no introduction. They produce the most popular protein powder on the market, Gold Standard Whey, which can be found in practically every supplement store in the United States.

Ultimate Nutrition has a slightly smaller reach, but they have a pretty dedicated following among bodybuilders, in part because they sponsor Mr. Olympia Phil Heath.

Both brands offer a variety of different protein powders (check out our reviews of Ultimate Nutrition’s Gold Whey and Iso-Cool), but we wanted to compare Gold Standard Whey with Prostar 100% Whey Protein, which seems like it was made to compete with Gold Standard. The two brands have nearly identical calories, macros, cost, and ingredients — but across these domains, we’ve stacked them up to see which is tops.

A blend of three kinds of whey that's extraordinarily creamy and surprisingly inexpensive.

The market's most popular whey lives up to its reputation as a solid all-rounder with a huge variety of flavors to choose from. It includes 24 grams of protein in each round scoop and mixes well with milk or water.

Optimum Nutrition Gold Standard

Both products have 120 calories per scoop, and ON has a pretty competitive macro split: 24 grams of protein, 3 grams of carbs (1 gram of sugar), and 1 gram of fat.

It’s also got 10 percent of your recommended daily intake of cholesterol (30mg), 5 percent of your daily sodium (130mg) and 8 percent of your daily calcium.

Ultimate Nutrition Prostar

While it has the same amount of calories and fat as Gold Standard, it has just a little bit more protein (25 grams) and fewer carbs (2 grams, 1 gram of sugar). This means the Ultimate Nutrition has more protein per calorie, but just barely.

The real difference is in the micronutrients: Prostar has about 30 percent less cholesterol (20mg versus 30mg), it has over two times more calcium (20 percent of the RDI versus 8 percent) and it has  far  less sodium (30mg versus Gold Standard’s 130mg).

On a macronutrient and micronutrient basis, Prostar comes out ahead.

Winner: Ultimate Nutrition Prostar

Ingredients

There are three kinds of whey in the following order: isolate, concentrate, and hydrolysed. Then there’s cocoa (we sampled the Double Rich Chocolate flavor), soy lecithin (for mixability), natural and artificial flavors, the artificial sweetener acesulfame potassium, and the digestive enzymes Aminogen and Lactase.

The ingredients are nearly identical. The same whey proteins in the same order, they both have soy lecithin, natural and artificial flavors, and acesulfame potassium.

There are two main differences: Prostar has a second artificial sweetener, sucralose (also called Splenda®) and it doesn’t contain digestive enzymes.

For these reasons, I think Gold Standard has better ingredients. Both sucralose and acesulfame potassium are controversial in some circles so it’s smart to only include one of them, but the main selling point was the digestive enzymes. These may help the user to absorb more of the protein and may minimize digestive issues among folks with lactose sensitivities — and  both  products contain lactose.

Winner: Optimum Nutrition Gold Standard

If you buy a standard two-pound tub, it’s $30 for 29 servings. That’s $1.03 per serving, or 4.31 cents per gram of protein.

A two-pound tub goes for around $29, which provides 30 servings. That comes to 96 cents a scoop or 3.9 cents per gram of protein.

The difference is small, but clear: Prostar delivers more protein for your dollar.

I tried the Double Rich Chocolate flavor, which despite the name is relatively mild. It’s closer to a dark, cocoa-y chocolate than a milk chocolate so while it’s great with milk, it’s pretty bland with water.

I picked up the Chocolate Crème flavor, and boy is it  creamy . For a product with 1 gram of fat, I was bowled over by how creamy it tasted. With milk, it made for a decadent shake that was almost like melted ice cream. But here’s the kicker: it tasted great with water.

Gold Standard, while an excellent all-rounder, doesn’t taste as great with water. Prostar, therefore, is more versatile — and it’s more useful for folks trying to lose weight because you can ditch the milk and save on calories.

Winner? A Close Call

These are both great products, and the fact that Prostar comes out ahead by a nose in some categories doesn’t mean that Gold Standard isn’t worth your money; it’s a very good product, and it has many flavor options to fit your individual tastes. They’re both fantastic, cost-effective proteins, and Gold Standard is most likely a better pick for folks with sensitivities to lactose. However, on the basis of taste and protein-per-calorie, I tend to prefer Ultimate Nutrition Prostar.
