Arginine is an amino acid with many important health benefits, but is best known for its key role in the production of nitric oxide, a potent factor in relaxing blood vessels and promoting blood flow. By increasing nitric oxide levels, Arginine has the ability to prevent plaque and blood clot formation and reduce the stickiness of platelets. Clinical studies have found high doses of arginine beneficial for many cardiovascular conditions including high blood pressure, peripheral vascular disease and angina.

In addition to its effects on blood vessels, arginine enhances the release of human growth hormone (hGH), enhances insulin sensitivity, supports liver detoxification, and has been shown to support interstitial cystitis, sperm formation, and treatment of brain injuries.

Since Arginine has so many beneficial effects on blood flow, people with cardiovascular disease, diabetes or metabolic syndrome can benefit greatly from supplementation. Athletes can also find great benefit from it since it supports healthy heart function, blood flow and exercise capacity.
