What experts liked

Gets excellent ratings for taste and effectiveness.
- BestReviews
We think Optimum Nutrition Gold Standard 100% Whey is the best protein powder because it easily won our taste test. That fact alone sold us on this protein powder, since our panelists disliked the flavor of many of the other options so passionately.
- New York Times Wirecutter
It mixes well with both water and milk, likely due to the lecithin, which helps to improve mixability. I typically shake up my protein in a mason jar, but even if you’re just stirring with a spoon, it dissolves nicely into the fluid
- Bar Bend
We like that Optimum Nutrition Gold Standard 100% Whey contains some natural ingredients, and we like the longevity of the company.

- New York Mag
You can have this protein powder in more than 20 unique kinds of flavor that can keep you healthy. This is likewise a without gluten item and easy to digest at the same time. This product is free of fat, lactose, cholesterol and other materials. It is the best-unflavored protein powder regarding ratings from genuine buyers.
- Products Browser
Gold Standard 100% Whey is approximately 81% protein, which is very high and a great value considering the cost. It is, of course, a lower content than you’ll find in a supplement made of pure whey protein isolates. The reason for this difference is that the ion exchange process, the means by which whey proteins are separated, is an expensive process. This is why whey protein concentrate is used as a secondary ingredient. This keeps costs down, making the product more affordable while not taking away from its muscle-building benefits.
- Smart Monkey Fitness
Different flavors to choose from.
- Hombre Golf Club
It is available in 23 delicious flavors, with three of them being natural flavors. Double rich chocolate has the best reviews.

One thing, which is interesting which I want to mention is this whey protein supplement review is its special feature to increase your hunger. You will feel hungry after consuming the protein shake, which means it has some digestive value.

What experts didn't like

If you don't want all whey,this may not be ideal for you.
- BestReviews
The main complaints we have about this powder are complaints we have about all powders—the taste is not, shall we say, delightful.
- New York Times Wirecutter
Contains artificial sweeteners.
- Bar Bend
We have reservations because of the reported bad taste and the ineffectiveness of the ingredients.
- dietspotlight
There were some issues with mixability, I needed to shake very well.
- Supplement Reviews
May cause stomach upset.
- Fighting Report
One problem with this supplement is that it contains artificial sweeteners. Depending on the flavor, it might contain sucralose (strawberry), acesulfame potassium (chocolate) or other additives, and this isn’t made clear on the labeling. Fitness buffs are careful about what they put into their body, so this could be a problem for some.
- Smart Monkey Fitness
The texture is very sandy.
- Hombre Golf Club
Optimum Nutrition Gold Standard Whey Protein Powder has a higher sodium content than comparable protein powders (130 mg).
- Develop Good Habits
Some find it tastes too bland when mixed with water
- Heavy
The flavored options contain Sucralose & Acesulfame-K.
- Fit Body Supplements
One disappointment I had in terms of taste with ON Gold Standard 100% Whey protein is its sweet taste. The sweetness I feel is too much, which could have been less. So, if you not much into the sweet flavor, you can avoid this drink.
- Editor Say
With the popularity and performance level of the Optimum Nutrition product, we felt like it would be beneficial to offer an unflavored option for those who prefer to mix their protein powder into their food. The three flavors do get boring after a while, and there are artificial sweeteners added to the product.

An Overview On Whey Protein Concentrates

Protein is important to life. Each of the body’s cells contains protein, and you may not be consuming enough of this important substance from your daily meals. Your daily protein intake will vary based on factors such as your body composition, age, weight and exercise levels.

If you find that you aren’t getting the recommended dose of protein through your diet, you can add a whey protein supplement to your daily regimen. While there are other protein sources, whey is preferable, thanks to its ability to digest quickly while being easy on the stomach.

When researching whey protein concentrate, first look to see that the product contains 100% whey with most of the whey coming from whey isolates. There are three types of whey (isolates, concentrates and hydrolysates), and the isolates contain the most protein. You’ll even find some whey protein powders are made using a nice blend with the majority of the protein coming from the isolates.

Check that the ingredients don’t interfere with your diet or known allergies. For example, Opportuniteas Grass Fed Whey Protein Concentrate is best for those who need a gluten-free, GMO-free, soy-free and artificial ingredient-free formula. It’s also cold-processed, which eliminates contamination from chemicals and toxins that some individuals may have a negative reaction to.

Next, if you’re an athlete, bodybuilder or exercise enthusiast, you’ll need to look at the amount of branched-chain amino acids (BCAAs) in the formula, as these are important for building muscle. An amount of 5.5 grams or higher is what you want to shoot for. If the product label lists the amino acids separately, you’ll need to add them all up to get the total.

Lastly, you’ll want to check for your favorite flavor (or taste test a few until you find your favorite). Some brands only offer two or three flavor profiles, while others have as many as 20. You may wish to use one flavor for shakes and smoothies and another flavor for baking.

The Whey Protein Concentrate Buying Guide

  • Always check for artificial ingredients and sugar content before deciding on a whey protein concentrate. This is especially important if you have a condition like diabetes or are allergic to dyes. Some brands sneak these not-so-beneficial ingredients into their formulas, so it’s always best to read the product label thoroughly.
  • Since whey protein concentrate is food, it does have an expiration date. There are a few things you can do to keep the product fresh for a long period of time. First, don’t transfer the powder into a new container. The original packaging is designed to keep moisture out. Second, place the protein powder in a location that is both cool and dry. In addition to water, heat can affect the supplement in a negative way.
  • Keep the whey protein powder out of the reach of children. Consuming too much of it at once can be harmful. Most of these supplements are not meant to be used by anyone under the age of 18.
  • Clumps within the powder and unpleasant odors are two signs that your whey protein concentrate has gone bad. This is true whether the product has reached its expiration date or not. If this happens, throw the container away and purchase a new one.
  • Get your family physician’s approval before adding any type of supplement to your diet, including whey protein concentrate. You want to make sure the formula you choose doesn’t interact with any of your medications. For example, whey protein stops the absorption of Levodopa, Formax and Tetracycline antibiotics.
  • Make sure the formula you use has been tested for banned substances. This ensures the product doesn’t contain any ingredients that would cause you to have a failed urine test for work or a competitive sports program.
  • You don’t just have to use the whey protein powder to make shakes and smoothies. You can also use them in food recipes, such as peanut butter cups, blueberry muffins and fudge brownies. If you prefer, you can also sprinkle the powder on top of your cereal, oatmeal or ice cream. It even mixes well with a small container of yogurt or an applesauce cup.
  • When considering the price of whey protein concentrate, you need to look at how many servings you get from the product. Then, you’ll need to divide the number of servings by the purchase price to see who has the most affordable protein powder. You’ll get 73 servings from the Nutricost Whey Protein Concentrate Unflavored, 15 from the Opportuniteas Grass Fed Whey Protein Concentrate and 69 in the NOW Sports Nutrition Whey Protein Concentrate.
