Whey Protein
What is Whey Protein?
Fast-digesting complete protein derived from milk. Rich in leucine and BCAAs. The gold standard post-workout protein.
How Whey Protein works
High leucine content (>10%) directly activates mTORC1 pathway to initiate muscle protein synthesis. Rapid digestion kinetics maximize post-exercise amino acid availability during the anabolic window.
Benefits & uses
- Builds & repairs muscle
- High leucine (strong MPS trigger)
- Convenient complete protein
- Supports recovery
Common uses: Protein synthesis, muscle recovery, post-workout nutrition, daily protein targets.
