From The Manufacturer

Unflavored whey protein powder is not tasteless, it has a natural taste of whey. Some like it plain with water, some with milk but you can get creative by adding extracts, fruits, milks, nut butters and natural powders. Have vanilla on Monday, strawberry on Tuesday, chocolate on Wednesday. Never get tired of the same flavor again. Our whey protein powder is not only made and packaged in the USA but sourced from farms in the USA. To filter the protein we use an advanced filtration system that gently processes whey to prevent the protein structure from becoming denatured. The process ensures the native amino acid profile is maintained. No acid or bleach is used in the process. Whether you’re a weight trainer, runner, cyclist, hiker or simply need a convenient boost of protein we’re here to help. We know the importance of consuming clean natural ingredients sourced from the US. If you’re health conscious and want peace of mind in knowing what's in your supplements and where they come from -- you’ve come to the right place.

What experts liked

Their non-GMO, all natural whey protein product is exactly that: clean whey protein with only two ingredients and no hidden surprises.
- Healthy Food Tribe
It’s suitable for men and women and can be used for pre-workout and post-workout recovery. Cases of side effects are very minimal since it doesn’t contain artificial flavors, fillers, additives, preservatives or sweeteners.
- Top Review Pro
Has natural formula and helps build lean muscle.
- The Supplement Reviews
The fact that this whey protein powder is unflavored doesn’t necessarily mean it’s tasteless. Whey has a natural flavor inherent to it, so it’s pretty hard to strip it of its natural flavor while maintaining the integrity of the product. That being said, as far as unflavored protein powders go, this is the best tasting in our opinion, and you can really make a delicious drink simply by adding it to your smoothie or mixing it with something else that you like.
- Workout N Recover
First of all, it is completely natural and doesn’t contain any additives, artificial colors, flavors, or sweeteners.
- My Parenting Journey
All natural formula.
- iast
It lets you add your preferred flavor, and it mixes well without lumps.
- Homethods
Competitive protein content.
- The Workout Digest
It's virtually tasteless, so you can add it to coconut water, peanut butter, or even your morning coffee without having to scrape your tongue afterwards.
- Wiki EZ Vid
TGS is proud of its USA roots. The whey comes from U.S. farms, and the protein powder is made and processed in the USA.
- Pure Path
The customer service at TGS Nutrition is excellent, and we enjoyed that it’s not an overly large organization like some of the other whey powder products on our list. It has a natural formula with no artificial sweeteners or additives and has a high protein count.
- Whey and Weigh

What experts didn't like

Does not taste that great.
- The Supplement Reviews
Since this product has no sweetness of its own; you will, no doubt, have to add some type of sweetener to your recipes.
- My Parenting Journey
Taste and source of protein could be better.
- iast
It has an unpleasant taste when taken alone.
- Homethods
Lack of grass-fed dairy means it can’t compete on additional fat content.
- The Workout Digest
The protein powder is packaged in a resealable bag, which is not as sturdy as the classic plastic containers many protein powders are sold in.
- Pure Path
Doesn’t have the greatest taste.
- Whey and Weigh

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.
