Legion Whey+ takes a science-first approach to protein supplementation, using 100% whey isolate from grass-fed, hormone-free cows. Founded by author Mike Matthews, Legion emphasizes evidence-based formulation and ingredient transparency. Each serving provides 22g of protein with 5.1g of BCAAs, naturally sweetened with stevia and erythritol.
Vega Sport Premium Protein is the top choice for plant-based athletes who need serious protein per serving. With 30g of protein from a four-source plant blend, it matches many whey proteins in protein content while being completely vegan. The NSF Certified for Sport designation means it is rigorously tested for banned substances, making it one of the very few plant proteins suitable for competitive athletes.
Vega Sport Premium Protein takes the lead with an overall score of 77 vs 75. For value, Legion Whey+ wins with a 66/100 value score.
