The Active Ingredient Is: L-Arginine

L-Arginine is an amino acid that takes part in everyday metabolic processes and acts as a starting point for nitric oxide production. It is provided here as a key supplement ingredient to support daily physiological function. This formula also has L-Citrulline and micronutrients that can help keep its activity going in the body, supporting NO production for cardiovascular upkeep.

What Does L-Arginine Do?

L-Arginine helps support nitric oxide production, which helps normal blood vessel relaxation and blood flow. This process supports cardiovascular function and overall circulation, lining up with how nutrients normally work. Together with L-Citrulline and micronutrients, it boosts the potential for lasting NO support.
