Since L-Arginine has been shown to promote dilation of blood vessels, it is commonly prescribed to people with cardiovascular disease and related health problems. The amino acid is seen to relieve the symptoms of clogged arteries and normalize the functioning of the heart. It may also alleviate the chest pains commonly felt by people suffering from heart disease. You can even start taking L-Arginine supplements to prevent developing heart disease, although this should only be done under the supervision of your doctor.
Since the amino acid dilates blood vessels, it can help lower blood pressure, as well as improve blood circulation in people with clogged arteries. Since Nitric Oxide is effective in preventing blood clots that can cut off blood supply to the heart, L-Arginine supplements are commonly given to help prevent chest pains (angina) by addressing nitrate imbalance.
