Fast-absorbing protein that supports muscle protein synthesis.
How it works
Whey protein provides all essential amino acids and is rapidly absorbed, triggering muscle protein synthesis via mTOR pathway.
Evidence-based uses
Whey isolate is faster absorbing. Concentrate is more cost-effective.
Clinical Evidence
Systematic review of 49 studies confirmed whey protein supplementation (20-40g post-exercise) significantly enhanced muscle protein synthesis and lean mass gains during resistance training.
Protein intakes of 1.8-2.7g/kg during resistance training consistently maximised muscle protein synthesis and prevented lean mass loss. Whey protein showed superior acute MPS response.
