Protein represents the building blocks of the human body. As a result, it is essential for muscle growth, repair, and function. Protein supplements are a popular and convenient way to ensure that your body is getting the protein it needs when it needs it.

For this review, we've gone deep into the whey protein isolate market to separate the best from the rest. The result is the seven best whey isolate proteins on the current market.

I've tried a lot of protein powders in my 35 years in the fitness industry. Kaged Whey Protein Isolate ranks as one of the best I've ever had and is the number one product on the market right now in terms of taste, mixability, purity, and price.
Let's start with the price. It breaks down to around $1.40 per serving, which is considerably cheaper than most competing whey isolates and is even on par with many whey concentrate powders. Better yet, if you become a Kaged Supplements subscriber, the cost will drop even further - down to around $1.25 per serving.
You get 25 grams of protein with every serving of Kaged Whey isolate. That includes a full 12 grams of essential amino acids. They have also thrown in Protease, which is a digestive enzyme. I have personally found that I'm able to absorb this protein without any gastric upset, which is not the case with other whey isolates, and I'm pretty sure it's due to Protease content.
This protein powder is available in five flavors, I haven't tried all of them, but the two that I have had - chocolate and chocolate peanut butter - were exceptionally good tasting. In fact, I had to check back on the label to make sure that they were actually healthy - which they were! You get just half a gram of fat and 2-4 grams of carbs, depending on the flavor. What's more, all five flavors are completely naturally flavored, so there are no artificial colorings or preservatives in the mix.
Kaged Whey Isolate also mixes really well and won't leave any gritty residue in the bottom of the cup.



Pros


+Well priced


+25 grams of protein


+12 grams EAAs

Cons

Transparent Labs 100% Grass-Fed is the top contender when it comes to getting an all-natural whey isolate. Every ounce of whey in their product comes from American grass-fed beef that is hormone free. You won't find any artificial flavorings, preservatives, or other additives in this product. In fact, it's got just four ingredients:


Whey isolate protein


Salt


Stevia


Natural flavoring


Each container of Transparent Labs 100% Grass Fed protein provides you with 28 grams of whey isolate. It has a protein-to-weight ratio of 88%, which is one of the highest in the business
. Each 32-gram serving contains 2 grams of carbs and one gram of sugar.
Transparent Labs 100% Grass Fed protein is available in eight tasty flavors, including Cinnamon French Toast and Milk Chocolate. I tasted the Milk Chocolate, and it was delicious. The only problem I had was that it didn't mix as well as I would have liked. While it didn't leave any clumps, it wasn't as smooth and frothy as the likes of Kaged Whey Isolate.



Pros


+Sourced from grass-fed cows


+28 grams protein


+88% protein-to-weight ratio




Cons


-Doesn't mix overly well







Best Grass-Fed Whey Isolate Protein Powder






Grass-Fed Whey Protein Isolate is sourced from grass fed American Cows! It contains one of the industry’s highest protein-by-weight ratios at 88% (28 grams of protein per 32 gram scoop)...

Swolverine Whey Protein Isolate delivers 26 grams of whey isolate per serving, with an impressive protein-to-weight ratio of 87%. That protein is sourced from grass-fed cows; Swolverine has also included a couple of key digestive enzymes (Protease and papain) to offset any digestive issues. This is a great addition that can make a big difference, especially if, like me, you experience bloating even when the lactose has been removed from your protein powder.
The best thing about Swolverine Whey Protein isolate has got to be the taste. It comes in an impressive range of flavors, including Vanilla, Chocolate, Honey Cinnamon Peanut Butter, and Mint Chocolate Chip. The one I tried was honey cinnamon peanut butter. I was a bit dubious of that combination, but my fears were put to rest from the first gulp. It was friggin' delicious! The biggest problem you're likely to have with this protein powder is that it tastes so good you'll have to exercise all your self-discipline not to overconsume it!



Pros


+Great tasting


+26 grams of whey isolate per serving


+Contains two digestive enzymes




Cons


-Low-calorie count means it's not suitable as a mass gainer
