L-ARGININE & L-CITRULLINE are amino acids that help the body produce nitric oxide (NO). The L-Arginine-Nitric Oxide pathway is a process in the body that converts L-Arginine into nitric oxide (NO) with the help of enzymes called Nitric Oxide Synthases (NOS). When taken orally, L-Citrulline turns into arginine, which raises the amount of arginine in the blood.

Suggested Use: As a dietary supplement, healthy adults take two capsules daily in the morning without food or as recommended by a qualified healthcare professional.
