L-Arginine

The Pro-Sexual Nutrient with Numerous Health Benefits

According to the Journal of the American Medical Association, 43% of women and 31% of men experience sexual dysfunction. Sexual dysfunction is difficulty experienced by an individual or a couple during any stage of a normal sexual activity, including physical pleasure, desire, preference, arousal or orgasm. This condition can exhibit itself as an aversion to, and avoidance of, sexual contact with a partner. In men, there may be failure to achieve or sustain an erection, or it may be a lack of excitement and pleasure in sexual activity.

Stronger Libido … Greater Endurance

L-Arginine is an essential amino acid and one of the building blocks of proteins in the body, and based on hundreds of studies, it is also known as a safe and effective pro-sexual nutrient for men. 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 and stronger, more powerful orgasms.
 

 

Here’s How L-Arginine Works

One of the main causes of erectile dysfunction in men is poor circulation. L-Arginine improves blood flow to the extremities, including the genitals, 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 is a precursor of nitric oxide (NO) in the human body. In the 1990s, scientists discovered that not only is Nitric Oxide an essential compound that helps blood circulation, but it is important to normal sexual function in both men and women. Without L-Arginine there would be no Nitric Oxide, and without it, men would not be able to have erections.

Nutritional expert, Dr. Jonathan Wright, explains the mechanism in men: “Molecules of Nitric Oxide (NO) are generated when an enzyme called NO synthase (NOS)—which is abundant in the nerve and muscle cells in and around the penis—strips away a nitrogen atom (N) from a passing molecule of the amino acid L-Arginine … and combines it with an atom of oxygen (O).”In other words, in order to produce nitric oxide in the body, a nitrogen atom must combine with an oxygen molecule in the blood. The enzyme called nitric oxide synthase controls this reaction. L-Arginine, the featured ingredient in Vydox Plus™, makes this happen and allows you to have harder, stronger erections.

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. 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. The daily dose of Vydox Plus™, contains 900 mg. of L-Arginine!

 

Scientific Studies

The potent effect of L-Arginine was demonstrated 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.

Animal Studies

Studies done on animals provide some evidence for effectiveness as well. In a laboratory study, two groups of rats were given free access to L-Arginine which was dissolved in their drinking water. Both groups had greater serum and penile concentrations of L-Arginine, and exhibited a significant increase in intra-penile pressure or “hardness.”

Serum and penile tissue levels of L-Arginine in the treated rats were increased by 64 – 148% compared to control animals. The penile nitric oxide levels also increased nearly 100% in the L-Arginine treated groups compared to the control groups. The researchers concluded that these data support the use of dietary supplements for treatment of erectile dysfunction.

L-Arginine is Essential to Several Systems in the Body.

Among its Many Roles, L-Arginine:

Among its Many Roles, L-Arginine:
• Is a precursor of nitric oxide (NO)
• Supports male fertility, improving sperm production and motility
• Increases muscle mass, while reducing body fat
• Helps reduce growth of cancerous tumors
• Promotes circulation resulting in improved blood flow
• Helps recovery after heart attack
• Stimulates the release of growth hormone
• Helps prevent and treat cardiovascular disease
• Improves immune function
• Reduces healing time of injuries
• Improves vascular function for patients with angina
• Plays a role in the formation of bone and tendons
• Reduces risk of blood clots and stroke
• Supports normal blood pressure

L-Arginine is an excellent supplement for anyone wanting to increase his or her sexual arousal, improve performance, and overall health. The huge advantage this natural and safe supplement has over Rx erection pills is that both men and women can take it, it’s considerably less expensive (Rx ED pills costs as much as $20 a pill!), and it’s been proven to work in numerous double-blind studies!

For maximum results, we suggest that you take Vydox Plus™ every day for at least 90 days in order for the ingredients to become concentrated in your body.
