The Active Ingredient Is: L-Arginine (Free-Form)

L-Arginine is an amino acid involved in normal protein metabolism and acts as a direct precursor to nitric oxide, a molecule that supports circulation. This form comes as free-form amino acids for potentially improved absorption.

This formula also includes L-Lysine and L-Ornithine, which help to support nitrogen balance and amino acid metabolism, contributing to overall metabolic health alongside L-Arginine.

What Does L-Arginine Do?

L-Arginine contributes to the production of nitric oxide, which helps relax blood vessels and support circulation. This can influence oxygen delivery to muscles during activity and support normal exercise-related metabolic processes.

In the context of normal physiology, these actions contribute to keeping energy and protein turnover during periods of increased metabolic demand, subject to individual nutritional status.
