L-arginine is the supplemental form of arginine, an amino acid produced by your body and obtained by eating certain foods. Dietary sources of arginine include meat, chicken, dairy and fish products. According to Medline Plus – a service of the National Institutes of Health – L-arginine supplements may successfully treat some cardiovascular diseases but not all. Consult your doctor to determine if L-arginine supplements may be right for you.
Effects
After consuming L-arginine supplements or dietary sources of arginine, your body converts it into the chemical nitric oxide, or NO. This process causes your blood vessels to widen and allow increased blood flow. This effect is referred to as vasolidation, and it may be beneficial if you suffer from poor blood flow due to clogged arteries. Other effects of arginine include promoting the release of growth hormone and insulin in your body.
Treatments
Arginine can treat a variety of conditions, according to Medline Plus. Congestive heart failure patients may benefit from L-arginine supplementation due to its ability to help clear up fluid in and around the heart. Arginine may also be effective for improving recovery times after illness or injuries, treating chest pain and reducing instances of cramping caused by clogged arteries in the legs. More research is need to conclude that arginine is effective as a treatment for erectile dysfunction, wound healing or high blood pressure.
Arterial Plaque
Arterial plaque builds up on the walls of your arteries over a long period of time. Your genes, diet and physical activity level play major roles in the amount of plaque buildup your arteries incur over time. The disease associated with clogged arteries is atherosclerosis. The Mayo Clinic states that L-arginine is an effective treatment method for atherosclerosis; however, it doesn’t say that the arginine removes the arterial plaque. It works by increasing blood flow around the plaque.
Safety/Risks
L-arginine is safe for most people when taken according to a physician’s recommendation. Medline Plus lists several minor side effects to be wary of, including stomach pain, diarrhea, asthma complications and low blood pressure. L-arginine may negatively interact with medications treating high blood pressure or medicines affecting blood flow, such as nitrates. Avoid L-arginine if you have had a recent heart attack because it may increase the risk of death, according to Medline Plus. Talk to your doctor to determine if L-arginine is a viable treatment option for you.
