  • L–Citrulline is an amino acid that has been found to play an important role in nitric oxide (NO) metabolism and regulation. L-Citrulline is converted to L-Arginine in the body, leading to increases in both L-Arginine and nitric oxide. Increased production of nitric oxide promotes vascular dilation, which helps support normal oxygen and blood circulation throughout the body.

    PHARMACEUTICAL GRADE L-CITRULLINE
    L–Citrulline is an amino acid that has been found to play an important role in nitric oxide (NO) metabolism and regulation. L-Citrulline is converted to L-Arginine in the body, leading to increases in both L-Arginine and nitric oxide. Increased production of nitric oxide promotes vascular dilation, which helps support normal oxygen and blood circulationthroughout the body.

    Nitric oxide is a gas molecule, not to be confused with nitrous oxide (laughing gas). It only has a half-life within the body of three to five seconds. This means that the moment NO is made it starts degrading. Bottom line, if you don’t have a constant supply of raw ingredients to rebuild your NO, you will fall short to gleaning its full benefits. To compound the NO challenge is the fact that as we get older our innate ability to make this critical substance drops, from as early as our 20s and steadily dropping that point onwards unless we take charge and do something about it. The consequence is that one or more the body functions are impacted with the decreased NO.

    At the American Heart Association, the president stated in 1998 that NO is one of the most important discoveries of cardiovascular medicine. Nitric oxide helps control blood pressure, enhances blood flow to the heart, brain, muscles, and entire body. NO is involved in immune function, respiratory performance, sexual performance, mental capacity, blood pressure, and so much more.
