Whey protein is a premium dairy protein that is quickly absorbed by your body and supplies essential amino acids for muscle support. This variant is sourced from milk and is typically processed to deliver a full amino acid profile for athletic recovery and growth support. Whey protein helps with supporting muscle protein synthesis and post‑training recovery, aligned with EFSA guidance on protein function. Dr. Tang from the University of Illinois found that whey protein is swiftly absorbed and contributes to muscle growth processes when paired with resistance training.
