Pros and cons

Clear Whey Isolate

  • 20 g of protein for 80 calories with zero sugar and fat
  • Informed Choice certified and verified under Informed Protein, per the brand
  • Light, juice-like texture that many find easier to drink than milky shakes
  • About $1.31 per serving for the 35-serving tub
  • Heavy foaming and slow dissolving are common complaints
  • Flavor reviews are split, with some finding it too sweet or medicinal
  • Uses sucralose, acesulfame potassium and artificial flavor despite 'naturally flavored' wording in some Amazon titles
  • 20 g of protein per scoop is modest

100% Grass-Fed Whey Protein Isolate

  • 28 g of protein per scoop from grass-fed whey isolate
  • Listed in NSF's Certified for Sport database and certified by Informed Choice (per the brand)
  • Every ingredient disclosed by weight, with batch test results published online
  • No artificial sweeteners, dyes or preservatives
  • buyers frequently describe it as easy on the stomach
  • About $2.17 per serving for the 30-serving tub, well above whey blends
  • Stevia can leave an aftertaste some people dislike
  • Made on equipment that also processes eggs, soy, wheat, shellfish, fish oil, tree nuts and peanut oil, and some flavors contain peanuts
  • Mostly sold through the brand site and Amazon, so in-store discounts are rare

Our verdicts

Clear Whey Isolate

Clear Whey Isolate is a smart option if milky shakes put you off: 20 g of certified whey protein in a light, juice-style drink for about 80 calories. Expect some foam and a learning curve with mixing, and sample flavors before buying the large tub, since taste reviews are genuinely split.

100% Grass-Fed Whey Protein Isolate

For shoppers who prioritize ingredient transparency and third-party verification, this is one of the strongest whey isolates available: 28 g of protein, a short stevia-sweetened ingredient list, NSF Certified for Sport status and public batch testing. The trade-off is price, at more than $2 per serving, and stevia's flavor will not suit everyone.
