L-Arginine is an amino acid that features in everyday biochemical pathways tied to blood vessel function and protein metabolism. In this product it comes as free form, a setup that’s quickly ready for absorption.

This form means the amino acid in its unbound state, letting it soak up by your body more easily.

What does L-Arginine do?

Dr Bailey from the University of Calgary found that arginine helps vascular health by supporting blood flow through the nitric oxide route, which means how amino acids behave in circulation.

The mix with citrulline here helps arginine availability and nitric oxide synthesis, which can keep normal blood flow and exercise performance in healthy people.
