Frequently asked questions
- Why does leucine matter?
- Leucine is the branched-chain amino acid (BCAA) that acts as the primary trigger for muscle protein synthesis. You need approximately 2–3 g of leucine per meal to activate MPS, which corresponds to roughly 25–35 g of high-quality protein.
- Is more protein per meal wasted?
- Not necessarily — excess amino acids are used for energy or other processes. However, the marginal benefit to muscle building from additional protein per meal plateaus after ~40–50 g for most people.
