Optimal Protein Distribution: Is 30g per Meal Really the Limit?

For decades, locker-room lore claimed that the human body can only absorb or utilize 30 grams of protein in a single feeding. Modern tracer studies show that while acute muscle protein synthesis saturates around 0.4g/kg per meal, larger doses are still fully absorbed and utilized for whole-body protein turnover.
The Leucine Threshold and mTOR Activation
To trigger maximal muscle protein synthesis, a meal must contain approximately 2.5 to 3.0 grams of the essential branched-chain amino acid leucine. Reaching this threshold requires roughly 25 to 35 grams of high-quality animal protein or 35 to 45 grams of blended plant protein.
Total Daily Intake Trumps Acute Micro-Management
Hitting your total daily target (1.6 to 2.2g of protein per kilogram of body mass) across 3 to 5 evenly spaced feedings accounts for 90% of the muscle-building stimulus.
