The Active Ingredient Is: L-Arginine

L-Arginine is basically an amino acid that shows up in everyday metabolism and acts as a building block for proteins. This form comes as pharmaceutical-grade amino acid and teams up with L-Citrulline to help sustain your body's amino acid pool.

This blend also contains L-Citrulline to help keep L-Arginine levels in the blood, supporting the overall quality of the formula.

What Does L-Arginine Do?

L-Arginine plays a role in making nitric oxide, a molecule that helps support healthy blood flow and circulation. This mechanism lines up with guidance from scientific sources and is part of keeping normal cardiovascular function.

Dr. Morita from Kobe University's team found that mixed L-Arginine and L-Citrulline can influence nitric oxide production, helping vascular function through daily activity.
