Arginine And Its Effect On Cardiovascular System




L-Arginine is an amino acid involved in numerous areas of human biochemistry, including ammonia detoxification, hormone secretion, and the immune system. It is is also well known as a precursor to nitric oxide, a key component of endothelial-derived relaxing factor. The endothelium is the lining inside blood vessels and arginine supplements help make more nitric oxide. Therefore, by making more nitric oxide, helps to relax and dilate blood vessels. Nitric oxide is a messenger molecule involved in a variety of endothelium-dependent effects in the cardiovascular system. There have been claims that this amino acid is useful in hypertension, preeclampsia, intermittent claudication, and erectile dysfunction. It has been studied for its role in athletic performance, burns and trauma, diabetes and syndrome X, male and female infertility, and interstitial cystitis. What does the research say about its benefits for various medical conditions?
Even though arginine supplements have been claimed to be useful for some of the conditions listed above, it would be premature to be overly excited. Much research needs to be done before we can be more confident about its role in health and disease. However, thus far, it appears to have a role to play in conditions involving blood vessel dilation. Whether the dilation is short lived or continues for an adequate period is still being evaluated.
