The Active Ingredient Is: L-ornithine (as L-ornithine hydrochloride)

L-ornithine is an amino acid that participates in normal urea cycle function, helping convert ammonia into urea for excretion and supporting energy metabolism pathways.

This form uses free-form L-ornithine hydrochloride, a stable presentation of the amino acid suitable for supplementation.

What Does L-ornithine Do?

L-ornithine is involved in ammonia detoxification and is a precursor to arginine and creatine, contributing to energy utilisation and muscle recovery processes in the body.

In physiological terms, it supports normal energy metabolism and the body’s capacity to manage protein-derived waste products during exercise and recovery.
