Protein Timing and Distribution: Optimizing Muscle Protein Synthesis

Daily protein is king — but smart distribution adds a noticeable edge.

Protein Timing & Distribution for Maximum MPS

Simple targets that add up to more growth.

Key Takeaways

  • MPS rises 3–5 hours after a protein-rich meal.
  • Hit the leucine threshold (~2–3 g; ~25–40 g quality protein).
  • 4 evenly spaced meals generally outperform 1–2 big ones.

Per-Meal Targets

Adults: ~25–40 g/meal (older adults 35–50 g). Roughly 0.4–0.55 g/kg/meal.

Sample Day (4 Meals)

  • Breakfast: 30–40 g
  • Lunch: 30–40 g
  • Post-workout/Afternoon: 30–40 g
  • Dinner: 30–40 g

Pre-Sleep Protein

30–40 g casein (or cottage cheese/Greek yogurt) to support overnight MPS.

Quality Matters

Favor complete, leucine-rich proteins (whey, eggs, meat; combine plants or use blends if vegan).
