The Active Ingredient Is: L-Arginine HCl

L-Arginine histamine hydrochloride is essentially an amino acid that your body uses for normal protein synthesis and as a precursor to nitric oxide, a signalling molecule involved in vascular function. This form provides the amino acid in a free, readily absorbed state.

This preparation is commonly suitable for vegetarians and vegans and is supplied as a free-form amino acid salt to support direct absorption.

What Does L-Arginine HCl Do?

L-Arginine participates in the production of nitric oxide, which relaxes blood vessels and supports normal blood flow and oxygen delivery to tissues. It also plays a role in protein synthesis and nitrogen metabolism, contributing to routine bodily functions.
