Leucine threshold
About 2.5–3 g of leucine per meal maximally switches on muscle protein synthesis.
2.5 g
One serving (2 tbsp) = 0.4 g leucine
Not a practical leucine source on its own. Treat it as a supporting protein and pair it with richer sources.
Pair it with
- Rice, oats or whole-grain breadGrains supply the methionine legumes and fruits lack.
- Sesame, sunflower or hemp seedsSeeds are rich in sulfur amino acids.
- Eggs or dairy (if vegetarian)Complete proteins fill every gap.
