Protein + Leucine
Leucine triggers muscle protein synthesis — pair with complete protein for full effect
How It Works
Leucine is the primary activator of the mTOR signaling pathway that triggers muscle protein synthesis (MPS). However, leucine alone isn't enough — you need complete protein providing all essential amino acids as building blocks. The threshold is ~2.5g leucine within a meal containing 20-40g protein.
Pro tip: Chicken breast or eggs provide both protein and leucine together
Best Food Pairings
Pair a protein-rich food with a leucine-rich food.
Foods With Both Nutrients
These foods provide meaningful amounts of both protein and leucine in a single serving.
Meal Ideas
- •Chicken breast (high leucine + complete protein)
- •Greek yogurt with eggs — both high-leucine foods
- •Whey in a smoothie with banana (natural leucine spike)
- •Tofu + edamame (combined leucine for plant-based option)
