what the evidence says
Whey protein is one of the best-evidenced supplements in sports nutrition: a large body of human trials shows that adequate daily protein, with whey as a convenient high-quality source, supports muscle growth and strength when combined with resistance training, and helps preserve lean mass in a calorie deficit. The evidence attaches to hitting total daily protein, not to any brand; powder is simply a cheap, consistent way to get there. Syntha-6 trades protein purity for dessert-grade taste, carrying more fat and sugar per serving; evidence-wise that is a compliance play, not a performance one.
Plain-language assessment of the human evidence. No cherry-picked citations.
