Erectile dysfunction and L- arginine
What is Erectile Dysfunction?
Erectile dysfunction, formerly called impotence, is the inability to obtain an adequate erection for satisfactory sexual activity. It's more common in men over 65, but it can occur at any age.
Remedies for Erectile Dysfunction
Here are five natural remedies that are used for erectile dysfunction:
L-arginine is an amino acid commonly sold in supplement form and obtained naturally in the diet. L-arginine-rich foods include plant and animal proteins, such as dairy products, meat, poultry, fish, and nuts.
Necessary for the production of protein, L-arginine also helps rid the body of ammonia (a waste product) and stimulates the release of insulin. In addition, L-arginine is used to make nitric oxide (a compound that relaxes the blood vessels). Although some studies suggest that L-arginine may benefit certain health conditions, other research shows that L-arginine may have harmful effects on some individuals.
Uses for L-Arginine
Proponents claim that L-arginine can benefit:
congestive heart failure
high blood pressure
sexual dysfunction in women
Some people also use L-arginine to boost the immune system, improve athletic performance, and shorten recovery time after surgery. L-arginine is also used for
Benefits of L-Arginine :
Studies indicate that L-arginine may help with the following conditions:
Several small studies show that increasing intake of foods high in L-arginine may help ease symptoms, increase exercise tolerance, and improve blood vessel function in people with angina.
2) Erectile Dysfunction
There's some evidence that L-arginine may benefit men with erectile dysfunction. In a 1999 study published in the journal BJU International, for instance, 50 men with erectile dysfunction took either 5 grams of L-arginine per day or a placebo. After six weeks, more men in the L-arginine group showed improvement compared to those taking the placebo.
Like the drug sildenafil citrate (Viagra), L-arginine is thought to enhance the action of nitric oxide and—in turn—relax the muscles surrounding blood vessels supplying the penis. As a result, blood vessels in the penis dilate, increasing blood flow, which may help maintain an erection. The difference in how they work is that Viagra blocks an enzyme called PDE5, which destroys nitric oxide, and L-arginine is used to make nitric oxide. Unlike Viagra, L-arginine is taken on a daily basis for erectile dysfunction.
3) Congestive Heart Failure
L-arginine may improve cardiac performance in people with congestive heart failure, according to a 2000 study published in Clinical Cardiology. However, the National Institutes of Health (NIH) caution that L-arginine should not be used in place of standard treatments prescribed by a healthcare provider.
More Research on L-Arginine
Studies also show that L-arginine may be effective for managing inflammation of the bladder, relieving leg cramping and weakness caused by blocked arteries (a condition known as intermittent claudication), and improving kidney function in kidney transplant patients taking cyclosporine. What's more, taking L-arginine in combination with ribonucleic acid and eicosapentaenoic acid (an omega-3 fatty acid) may reduce recovery time, protect against infection, and promote wound healing after surgery.
According to the NIH, there's not yet enough evidence to rate the effectiveness of L-arginine in treatment of migraines, dementia, high blood pressure, male infertility, and the common cold. It's also unknown whether L-arginine can boost the immune system and/or improve athletic performance.
Additionally, L-arginine appears ineffective for prevention of heart attack and treatment of preeclampsia.
