Arginine also referred to as L-arginine, is an amino acid, which your body makes. It is not an essential amino acid (e.g. a one that your body cannot produce) but we still get some from foods. Arginine may alleviate various symptoms, ranging from inflammation to migraines.
Why do you need arginine?
People need arginine because it has cardiovascular benefits and relaxes the blood vessels.
Research shows that it can provide relief from angina and peripheral arterial disease. It seems to improve the health of individuals suffering from cardiac disease. When combined with other supplements, such as pycnogenol, it can also act as a cure for erectile dysfunction. Some studies have proven its immunity-boosting effects. This nutrient can also fight the symptoms of weight loss caused by HIV.
It has been known to assist kidney function after a transplant and also alleviates symptoms of kidney inflammation. Studies show that it can ease migraines, improve recovery time after surgery and relieve hypertension (1, 2, 3, 4).
The use of L-arginine as a sports and body building supplement is quite popular. Several studies have shown the positive role of L-arginine in boosting stamina, physical endurance and muscular gains. It is believed to help improve physical growth due to its ability to increase growth hormone release and due to its positive effect on nitric oxide levels. The increase in nitric oxide, in turn, helps improve the supply of blood to the muscles leading to a substantial improvement in growth (5, 6, 7).
The trend of consuming arginine as a supplement is on the rise. However, most people appear to get an adequate amount of arginine from foods and might not get much benefit from supplements.
But in some cases, doctors and nutritionists may recommend supplemental arginine.
Individuals with protein malnutrition, infections, burns, and other conditions may require arginine supplementation.
There is no established standard dose of arginine but most doctors recommend a daily intake of 1 200 mg.
Your required daily intake varies from person to person depending upon conditions. Professional athletes may need up to 20 g of arginine per day.
Ask your doctor for advice if you want to know how much arginine you need and/or if you are considering taking arginine as a supplement over an extended period of time.
