A pure, clinically dosed amino acid designed to kickstart muscle protein synthesis and support lean muscle recovery. NutraBio L-Leucine delivers 3,000 mg of high-grade, naturally fermented leucine per serving — no fillers, no blends, no compromise.
L-Leucine is the essential amino acid that acts as the “trigger” for muscle growth. Without enough leucine, recovery slows, strength gains stall, and training progress plateaus. This formula provides a clean, vegan-sourced leucine that mixes into shakes or intra-workout blends for daily recovery support. Add it to your post-workout routine or pair it with EAAs/BCAAs to reinforce training adaptation. When your body gets the signal to grow — results follow.
L-Leucine (3,000 mg):
The key anabolic signal that activates mTOR — the pathway responsible for muscle protein synthesis and recovery. Supports lean muscle building, strength progress, and post-training repair.
Mix 1 scoop (3g) into your post-workout shake or intra-workout drink. Use daily to support recovery, strength progression, and lean muscle maintenance.
We carry NutraBio L-Leucine because muscle recovery isn’t optional — it’s the foundation of strength progression. This is a clean, single-ingredient amino that supports serious lifters and athletes who want to consistently increase performance and maintain muscle quality.
