L-Arginine and Erectile Dysfunction: Can It Work?

Natural treatments for erectile dysfunction are hard to trust at times because you don’t know what most of the ingredients are or what they do. Luckily, you have a starting point because there is one ingredient that you should always look for.

If you have done any research on natural male enhancement, you have probably encountered a product or two that contains L-arginine, an amino acid that promotes the production of nitric oxide.

L-arginine has a myriad of health benefits, but it has primarily been found to be effective in the treatment of erectile dysfunction. It has been so publicized that many have been led to wonder if it could present a cheaper, safer alternative to more popular and pricey supplements like Viagra and Cialis.

How it Works

L-arginine functions in much the same way as sildenafil citrate, also known as Viagra. It enhances the action of nitric oxide, thereby relaxing the muscles surrounding blood vessels and supplying the penis with blood. When this occurs, blood vessels in the penis dilate, increasing blood flow, which may help a man maintain an erection as more blood rushes to the penis.

While both L-arginine and Viagra deal with nitric oxide as a treatment for erectile dysfunction, Viagra blocks the enzyme PDE5, which destroys nitric oxide, and L-arginine actually helps to produce nitric oxide. Another difference is that L-arginine is taken on a daily basis for erectile dysfunction, while Viagra is taken only when sexual intercourse is anticipated.

Is it Proven to Work for Erectile Dysfunction?

When you’re researching ingredients in male enhancement supplements, you want to be sure that each has professionally performed studies testifying to its usefulness. In the case of l-arginine, there are several.

The most convincing, perhaps, is a 1999 study published in the journal BJU International. During the study, 50 men with erectile dysfunction took either five grams of L-arginine or a placebo every day. After six weeks, more men in the L-arginine group showed improvement compared to those taking the placebo. Though it does work more slowly than other stimulating ingredients, it is worth trying if you are seeking male enhancement.

However, you should be sure to check your prospective supplement for dosage information. To be effective, L-arginine must be included is a dose of at least 5mg.

Are There Other Benefits?

Arginine also triggers the body to make protein and has been studied for bodybuilding and the enhancement of sperm production. It has also been linked to an increase in libido in both men and women.

And because it increases the capacity of blood vessels, it allows more blood and nutrients to flow to muscles. So, if you’re looking to bulk up a little, l-arginine in your male enhancement supplement could give you an extra boost.

Final Thoughts on L-Arginine

Since erectile dysfunction can be caused by a variety of factors, including aging, diabetes and other endocrine disorders, is it unreasonable to assume that L-Arginine will be effective in all cases.

However, it will be most effective in those men whose erectile dysfunction is a result of low levels of nitric oxide. Optimal nitric oxide production will ensure ideal erectile function, and for many people with sexual dysfunction, arginine-based supplements will ensure adequate nitric oxide levels.
