L-Leucine & L-Tryptophan: Small Ingredients, Big Impact

At Crux Nutrition, every ingredient in our gel has a purpose. Two that quietly make a big difference are L-Leucine and L-Tryptophan — essential amino acids that support both body and mind.

🧬 L-Leucine

Known as the “switch” for muscle recovery, L-Leucine triggers protein synthesis — the process that repairs and rebuilds muscle after training. It helps reduce soreness, preserve lean muscle, and accelerate recovery so you’re ready to go again.

🌙 L-Tryptophan

L-Tryptophan supports serotonin production, helping regulate mood, focus, and mental endurance. It keeps your head clear and motivation high when fatigue sets in — vital for long sessions or competitions.

⚡ Why We Use Them

Most gels just fuel your muscles. Ours go further. With collagen for joint support, fast carbs for clean energy, and amino acids like L-Leucine and L-Tryptophan, Crux Nutrition – Recover is built to fuel and restore in one hit.

Fuel smarter. Recover stronger.
