Pros and cons

Organic Protein Plant-Based Protein Powder

  • Low cost for an organic protein (about $1.60 per serving on Amazon)
  • USDA Organic, vegan and made without soy, dairy or gluten ingredients
  • 7 g of fiber and less than 1 g of sugar per serving
  • Huge review base: 4.5 stars from more than 65,000 buyer ratings
  • A July 2026 proposed class action alleges undisclosed lead, cadmium and arsenic; Orgain says its products are safe
  • Only 21 g of protein per 46 g serving, with the lower leucine typical of plant blends
  • No published batch heavy-metal testing or sport certification
  • Texture can be gritty or slightly chunky in water, according to some reviewers

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

Organic Protein Plant-Based Protein Powder

Orgain Organic Protein is an affordable, widely available organic vegan powder that most buyers find pleasant in smoothies. Its protein per serving is modest, and the 2026 heavy-metals lawsuit plus the lack of published contaminant testing mean shoppers who prioritize purity may prefer a plant protein with third-party certification.

Full review

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.
