L-arginine
L-arginine is a form of amino acid that plays an important role in the building of protein in the body. It can be found in most sources of protein, including dairy products, beans, whole grains, soy, poultry, red meat, and fish. You can also take L-arginine supplements to help reduce levels of blood pressure. It may be taken topically, orally, or injected intravenously. L-arginine works as a vasodilator, meaning it can dilate or open blood vessels. Therefore, many people may take this supplement to treat heart diseases. Those with erectile dysfunction can also benefit from L-arginine. Other studies have also found that amino acids can significantly improve blood flow and blood vessel functions. [8]
