Frequently asked questions
- How much protein do I need per day?
- The minimum RDA is 0.8 g/kg/day. Active people and those building muscle typically benefit from 1.2–2.0 g/kg/day. Most high-quality research suggests 1.6 g/kg is sufficient to maximise muscle protein synthesis.
- Does it matter when I eat protein?
- Spreading protein across 3–4 meals of 25–40 g each maximises muscle protein synthesis compared to eating it all at once.
