Protein Timing & Anabolic WindowHealth

Post-Workout Protein Timing & Muscle Protein Synthesis (MPS) Calculator

Calculate your optimal per-meal protein bolus (0.4g–0.55g per kg) to maximally trigger muscle protein synthesis (MPS) across 3 to 5 evenly spaced daily meals.

Calculation Methodology

Per-Meal Target (g) = Total Daily Protein Target / Number of Daily Meals. Minimum effective leucine threshold = ~25g–40g quality protein per meal.

Important Legal & Educational Disclaimer

Modern exercise physiology shows that distributing protein evenly across 3–5 feedings optimizes 24-hour muscle hypertrophy compared to single large boluses.

Frequently Asked Questions

The strict 30-minute window is a myth. The optimal anabolic opportunity extends 3 to 5 hours surrounding your workout, provided total daily protein needs are met.
