Optimum Gold Standard 100% Casein

Optimum Nutrition Gold Standard Whey Review (Updated: More Popular Than Ever?)

Whey protein’s slower-digesting cousin, casein protein is a favorite among physique athletes and bodybuilders looking to hit an ambitious protein target or kill nighttime cravings. The thicker texture of casein makes it an ideal substitute for puddings and ice creams, and the overall feedback from customers is this is their go-to snack option to satisfy their sweet tooth and prevent muscle loss.

What the Community Says:

“Of all the supplements on the market, this is absolutely the best and the one that really works! And if for some reason you miss a workout or need to lay off for a while, continue taking this to help maintain the gains you’ve made. I never mix anything with this other than occasionally adding a dash of pumpkin pie spice to make it taste exactly like eggnog. I drink this while watching a bit of TV before bed and when I’m finished, I always feel a bit pumped. Jump into bed and off I GROW!” rorinsmith

“Great in the evening, and to make a protein fluff.” Fabiano10

“Very good protein, mixes well. I use this as an evening snack.” Sorgedb

Whey Protein Isolate Vs Concentrate Vs Peptides Which Is Best

One thing you may have noticed with ONs Gold Standard is that, rather than just having a single type of whey protein available, they are using all three. This is interesting since, as mentioned, most other brands tend to stick with one over the other. Each type of whey protein has its specific pros and cons. As such, knowing how the three operate can give you a better understanding of why youd pick one over the other, as well as why ON decided to capitalize on all three instead of just choosing one.

  • Whey Protein Isolate is known for having the highest percentage of protein in the group. The problem, however, often comes in the process used to make it, as it often reduces much of the other beneficial ingredients in whey, such as whey peptides, which are known to improve health and overall immunity.
  • Whey Protein Concentrate is considered the cheapest of the three due to it having the lowest amounts of available protein when consumed. Conversely, it also has the most amount of fat, beating out both whey peptides and whey protein isolate. This isnt necessarily a bad thing, as there is also a high amount of conjugated linoleic acid which is known for burning fat in the body.

Should You Buy Gold Standard Whey Protein

While I was happy with ON Gold Standard, I wouldnt say its the best protein powder out there.

For a whey protein powder, its great.

But it doesnt contain Casein.

Whey protein hydrolysates, like those found in Gold Standard, are great at allowing you to process protein in record time. But good sports nutrition is all about balance.

Casein, another form of protein, is digested much slower by your body. By combining both fast and slow absorbing protein, you get a more consistent result.

For this reason, I recommend Tri-Protein by Crazy Nutrition.

It delivers everything Gold Standard promises plus much, much more.

This includes an incredible 6 different types of protein which are released over three separate phases. Helping fuel your body consistently over a 24-hour period.

One Of The Best Protein Powders Out

One of the best protein powders I’ve had, it mixes really well. You hardly get those powdery clumps. It hasnt got that fake home brand flavour like most powders. Ive tried the choc mint and the banana and they were both amazing. Not overly expensive either.


Versatile and great tasting, healthy protein powder. This goes with everything and also makes amazing smoothies. I go to the gym 4-5 days a week and this is my go-to protein every time.


Amazing protein – recently ordered the coffee flavor and tastes amazing mixed with water or milk defiantly one of the best tasting I have had and I have tried a lot over 20 years . Excellent value for money per serve and great macros

Taste Texture & Mixability

Optimum Nutrition Performance Whey Protein Powder Review

Hydrolyzed whey can often be quite bitter due to the protein purity. Masking this bitterness can be a challenge for manufacturers, but Optimum has done well. We tried both the Turbo Chocolate and Velocity Vanilla and didnt taste a hint of bitterness. We were especially surprised that we didnt notice it with the vanilla, however, it was a bit too sickly sweet for us. This is probably to try and mask this bitterness. The chocolate was great however and the flavor is pretty much identical to Optimums popular Gold Standard product.

Optimum Nutrition Whey Taste

Optimum Nutrition sells some twenty different flavors, and they know their chocolate. The line includes Double Rich Chocolate, Extreme Milk Chocolate, Chocolate Malt, Chocolate Peanut Butter, Chocolate Coconut, White Chocolate, and Rocky Road .

We purchased the most normal-sounding chocolate: Double Rich Chocolate. Despite the double in the title, its tasty without being overwhelmingly sweet or intensely flavored. Its closer to a dark chocolate taste than milk chocolate. If youre after a sweeter, creamier, more intense chocolate, you might prefer the equally popular Extreme Milk Chocolate flavor.

Some flavors from ON are nice as a one-off but easy to get sick of after a few shakes . Double Rich Chocolate is ONs standard, basic chocolate. Its reliable and mild enough that it wont overwhelm the palate, and consumers probably wont get tired of it. Note that the flipside of this low intensity chocolate is that its very, very bland when mixed with water.

How Does Gold Standard Whey Protein Work

Does the science back up this multi-whey protein blend?

To find out, I took a closer look at some core ingredients found in the Double Rich Chocolate Gold Standard Whey Protein.

Heres what I discovered.

  • Whey Protein Isolate : WPI is up to 95% pure making it the blends primary source of protein. Low fat, low carb, and virtually lactose-free, it has been specially processed and refined to make it fast-acting and easy to digest. This 14-day study shows how WPI accelerated the recovery rates of 14 participants. Isometric knee extension strength was also found to be significantly higher after taking WPI.
  • Whey Protein Concentrate : WPC has around 70-80% protein and contains more fat and lactose than WPI. This 21-week study measured the cross-sectional muscle of 31 participants. The men were split into three groups and asked to undergo resistance training. At the end of the study, the group consuming whey protein was found to have increased leg muscle mass compared to that of the individuals in the placebo and control groups.
  • Whey Peptides: Peptides are broken down more than other whey variants. This is done to hasten the absorption of protein by the body . This 3-day study took 12 men and tested their recovery rate. Each participant was given a whey supplement containing 25g of protein. The study found that the men taking whey hydrolysate post-exercise recovered faster.

And for those pro athletes, youll be happy to hear that Gold Standard is banned substance tested.

Is Gold Standard Whey Protein Powder Gluten

Optimum Nutrition Gold Standard Whey Protein Mocha Cappuccino Flavor Review

Yes, Gold Standard Protein Powder is Gluten-Free.

Whey protein is a source of protein that comes from milk. Some people who are Celiac may be concerned about whether or not Gold Standard protein powder is gluten-free.

According to Healthline, Optimum Nutrition Gold Standard Whey Protein Powders are gluten-free and safe for individuals who are gluten intolerant or have Celiac Disease to consume.

While many Optimum Nutrition Gold Standard Whey does not include ingredients containing gluten they are manufactured in a plant that carries gluten-containing products.

Gold Standard Whey Benefits And Effectiveness

As mentioned above, the blend of three kinds of whey helps make this a very well-rounded product. Contrary to popular belief, theres no one best kind of whey. They each come with their own benefits, and mixing them all was a smart move by ON. Many of the benefits of this product come from the fact that it contains whey, a high-quality protein containing Branch Chain Amino Acids , and other non-essential amino acid glutamine.

The macros make this a solid choice for folks on low-carb diets or low-fat diets. Aminogen and Lactase should improve digestion, but besides that, theres not a lot else in this product. Its several kinds of whey and some enzymes to help you make the most of it.

On Gold Standard Whey Taste

(VIDEO Review) Optimum Nutrition Gold Standard Whey Protein Banana ...

While it is a protein powder and thus not amazing compared to actual delicious drinks its amazing within the category of protein powders.

The flavor weve been using is double chocolate . This is a relatively subtle taste that doesnt feel particularly sugary, chemical, or have any of the lingering whey taste you experience with some brands.

The texture is great, the end result is pleasant and even enjoyable when using 2 scoops in 500ml of milk, so its clearly not overpowering. The end result is a chocolate-ish, creamy flavor that I actually anticipate eagerly.

Its not a chocolate milkshake, but its a great attempt for a healthy, pro-muscle supplement.

Whether youre looking to burn fat or build muscle, consuming an adequate amount of protein is going to play a large role in your success. Many people do not meet the recommended dietary allowance of 0.8 grams of protein per kilogram of body weight, as recommended by Harvard Medical School. For those people that do not eat enough protein-dense foods throughout the day, a quality whey protein powder can be a good solution to bump daily intake.

And what are the building blocks of protein? Amino acids. But some foods youre eating may not contain all nine essential amino acids. Essential meaning your body cannot make them and so must get them from food. This is where whey protein can help.

A quality whey protein powder will contain not only the essential amino acids, but higher amounts of the three most important for muscle building. These three, valine, leucine, and isoleucine, are called branched-chain amino acids and are more commonly referred to as BCAAs.
