The Active Ingredient Is: L-Ornithine (as L-Ornithine Hydrochloride)

This presentation emphasises purity and transparency, with the ingredient sourced and manufactured to maintain vegetarian and kosher status in allergen-controlled environments.

What Does L-Ornithine Do?

L-Ornithine plays a role in the normal functioning of the urea cycle, helping to remove ammonia produced during protein metabolism. It is involved in amino acid metabolism and may contribute to downstream production pathways related to arginine, citrulline, proline, and glutamate, supporting healthy metabolic processes in line with EFSA guidance.
