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

L-Arginine is a naturally occurring amino acid used by your body in protein metabolism and different metabolic pathways. When supplied in free form, it is quickly available for your body\'s use.

This mix also includes L-Lysine and L-Ornithine, which help nitrogen balance and amino acid metabolism, contributing to overall protein turnover and tissue repair processes.

What Does L-Arginine Do?

Dr. Bescós from the University of Navarra found that arginine can act as a precursor for nitric oxide, which helps regulate blood flow and nutrient delivery to tissues during activity. This aligns with EFSA and NHS views of arginine\'s role in normal vascular function.
