The Active Ingredient Is: L-Ornithine

L-Ornithine is an non-essential amino acid that participates in normal amino acid metabolism. This form is commonly supplied in vegan capsules and is used in formulations containing L-Ornithine in combination with other ingredients to support metabolic pathways.

In this product, L-Ornithine is provided via a form derived from L-Ornithine hydrochloride, with the capsule presentation designed for vegan-friendly intake. This substance serves as a metabolic intermediate involved in the body’s nitrogen management processes.

What Does L-Ornithine Do?

L-Ornithine plays a role in the urea cycle, helping to convert ammonia into urea for clearance from the body. It also contributes to the production of arginine, which is linked to nitric oxide synthesis and vascular function, and can be converted into other amino acids and related compounds related to energy and protein metabolism.

This supports normal metabolism and amino acid balance, aligning with scientifically recognised roles for L-Ornithine in healthy physiological function.
