L-Arginine: for good erections and much more...

¬L-Arginine, the Pro-sexual Nutrient

Based on dozens of studies, Arginine, an essential amino acid and one of the building blocks of proteins in the body, has become known as a safe and effective pro-sexual nutrient for men and women.

L-Arginine is a precursor of nitric oxide (NO) in the human body. In the 1990s, scientists discovered that not only is NO an essential compound that helps blood circulation, but it is important to normal sexual function in both men and women. Without arginine there would be no NO, and without NO men would not be able to have erections.

How L-Arginine works

Insufficient blood flow is a major cause of incomplete erections in men. L-Arginine has been shown to improve blood flow to the genital area by dilating blood vessels and helping the penis to enlarge to its full capacity, thus increasing the size, hardness and frequency of erections.

L-Arginine has a similar effect in women

Higher blood flow makes clitoral and vaginal tissues more sensitive and responsive to sexual stimulation, and helps increase the possibility of reaching orgasm. Although there haven't been nearly as many studies done on arginine supplementation in women as in men, one study found that postmenopausal women who took a supplement including L-arginine experienced heightened sexual response.

Another study involving 77 women of all ages found that after four weeks, 73.5% of the women who took a supplement including L-arginine experienced greater sexual satisfaction, including heightened desire and clitoral sensation, frequency of intercourse and orgasm, and less vaginal dryness.

Both men and women report that L-arginine seems to increase their libido or desire for sex, and some also report that L-arginine gives them greater endurance. Reports also suggest that L-arginine supplements can improve fertility in men who have low sperm counts or poor sperm motility (activity).

Scientific studies

The powerful effect of L-arginine was illustrated in a double-blind, placebo-controlled study published in the British Journal of Urology International in which researchers evaluated the nitric oxide levels of 50 men with erectile dysfunction. The men were given either L-arginine or a placebo for six weeks. Nine of the 29 men (31%) given L-arginine reported a significant improvement in their sexual performance. These nine men had low nitric oxide levels at the start of the trial, but their levels doubled by the end of the study.5

It is important to note, however, that erectile dysfunction can be caused by a variety of factors, including aging, diabetes and other endocrine disorders. L-arginine may be effective only in those men whose erectile dysfunction is due to low levels of nitric oxide. In fact, in one study in which the participants suffered from impotence for a variety of reasons, L-arginine was found to be effective in only 17% of the patients.6 However, optimal nitric oxide production will ensure optimum erectile function, and for many people with sexual dysfunction not related to an underlying disease arginine supplements will ensure adequate nitric oxide levels.

The positive benefits of arginine go beyond sexual enhancement

This remarkable amino acid helps build muscle mass, enhance immune function, improve blood pressure, increase memory, and speed wound healing.8-10 Arginine-derived nitric oxide has also been found to play a supporting role in the cardiovascular, immune, and nervous systems and has been validated by hundreds of studies.

L-Arginine is essential to several systems in the body.

Among its many roles, L-arginine:

Is a precursor of nitric oxide (NO)

Promotes circulation resulting in improved blood flow

Stimulates the release of growth hormone

Improves immune function

Reduces healing time of injuries

Plays a role in the formation of bone and tendons

Increases muscle mass, while reducing body fat

Supports male fertility, improving sperm production and motility

Reduces risk of blood clots and stroke

Supports normal blood pressure

Improves vascular function for patients with angina

Helps recovery after heart attack

Helps prevent and treat cardiovascular disease

Helps reduce growth of cancerous tumors

Timing and contra-indications

L-arginine users say they can achieve a prosexual effect by taking it 45 minutes before sex. There are few reported side effects. The most notable are:

People with herpes - L-arginine may increase the severity of attacks, but some reports indicate that it may also enhance your immune function enough so you are less likely to get herpes attacks.

L-arginine is an excellent supplement for anyone wanting to increase his or her sexual arousal, improve performance and overall health.
