Our verdicts
Whey+ Grass-Fed Whey Protein Isolate
Legion Whey+ is one of the most credible naturally sweetened whey isolates, pairing certified grass-fed sourcing with public lab testing. You get slightly less protein per scoop than some rivals and pay a premium, but for buyers avoiding artificial sweeteners who want proof of what is in the bag, it is an easy recommendation.

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.
