Is there a maximum protein per meal?
~40g maximizes synthesis per meal. More isn't harmful but doesn't provide additional muscle-building benefit.

What this calculator does
A protein per meal calculator distributes daily protein target across meals for optimal muscle protein synthesis. Research suggests 20-40g per meal maximizes synthesis, with higher amounts for older adults and larger individuals.
How it works
Enter daily protein target and number of meals. Calculator distributes evenly with adjustments for meal timing.
Formula
Per meal = Daily protein ÷ Number of meals. Optimal range: 20-40g per meal. Post-workout: prioritize protein meal.
Tips for using this calculator
- 20-40g per meal optimizes muscle protein synthesis
- More than 40g isn't harmful but may not add benefit
- Post-workout meal should include protein
- Breakfast often lacks protein—prioritize it
- Evenly distributed intake beats back-loading
Frequently asked questions
Does meal timing matter?
Somewhat. Even distribution across day is better than one large protein meal. Post-workout is slightly beneficial.
What about protein before bed?
Casein or mixed protein before bed can support overnight muscle protein synthesis.
