Natural Remedies for Erectile Dysfunction
Natural Remedies for Erectile Dysfunction
Here are five natural remedies that are used for erectile dysfunction.
1) L-Arginine
L-arginine is an amino acid that the body uses to make nitric oxide, a substance signals smooth muscle surrounding blood vessels to relax, which dilates the blood vessels and increases blood flow. Relaxation of smooth muscle in the penis allows for enhanced blood flow, leading to an erection.
L-arginine is found naturally in foods such as meat, dairy, poultry and fish. It is also available as oral L-arginine supplements, which some product manufacturers market as a "natural Viagra").
There have only been two studies to date, however, evaluating the effectiveness of L-arginine for erectile dysfunction.
One study involved 50 men who took L-arginine (5 grams a day) or a placebo. After six weeks, significantly more men taking L-arginine experienced an improvement in sexual function compared with men taking the placebo. Interestingly, it only benefited men who had initially low levels of nitric oxide.
Another study using a smaller dose of L-arginine and a shorter treatment duration found no benefit with L-arginine use. The study involved 32 men with erectile dysfunction who took oral L-arginine supplements (500 milligrams three times per day) or a placebo for 17 days. Oral L-arginine was no better than the placebo.
Side effects may include digestive complaints. High dosees of L-arginine may stimulate the body's production of gastrin, a hormone that increases stomach acid. For this reason, L-arginine may be harmful for individuals with ulcers and people taking drugs that are hard on the stomach.
L-arginine may also alter potassium levels in the body, especially in people with liver disease. It should not be taken by people who are on medications that alter potassium levels, such as potassium sparing diuretics and ACE inhibitors.
