Healthy kidneys don't mind.” ## Why it works Its muscle effect is the familiar one. It is rich in leucine and digests fast, giving a sharp rise in amino acids that triggers mTOR and muscle building. The less advertised part is its cysteine. Cysteine is the limiting ingredient for glutathione, so whey supports the body's main in-house antioxidant in a way plain amino acid blends do not. ## Where it fits Whey Protein Concentrate is a move in 10 protocols.
