LifeSource Vitamins Whey Protein Concentrate — Grass-Fed — Muscle Growth & Recovery Support*
Our Whey Protein Concentrate combines premium grass-fed whey protein concentrate (WPC) in a delicious, stevia-sweetened formula to support muscle protein synthesis, promote post-exercise recovery, support daily strength goals, help maintain lean mass with training, promote satiety and appetite control, support healthy post-meal responses within normal range, promote antioxidant defenses via bioactive peptides, and support overall wellness* — while respecting traditional use. Cross-flow micro-filtration at low temperatures preserves native whey fractions. Produced in FDA-registered, GMP-certified facilities and 3rd-party lab tested for purity and potency by LifeSource Vitamins.
