Leucine Threshold per Meal
Leucine threshold per meal is the leucine dose—about 2–3 g—that supports muscle protein synthesis. Spread protein across meals rather than one large serving.
Leucine threshold per meal is the leucine dose—often roughly two to three grams per meal for adults—that helps trigger muscle protein synthesis, especially after training and in older adults. Spread protein across three to four meals instead of one giant dinner.
Twenty-five to forty grams high-quality protein usually clears the threshold.
Common questions
-
Do you need leucine supplements?
Whole food protein—whey, eggs, chicken, soy—usually provides enough leucine per meal. Supplements help only when meals are chronically low protein.
