ARGININE

A 1999 study, which sought to determine if supplemental arginine was a sound alternative treatment for erectile dysfunction, found that arginine (5 grams daily for 6 weeks) significantly improved subjective measures of sexual function only in subjects who initially had low nitric oxide levels.

However, a 2000 placebo controlled cross-over study found that arginine, at a dose of 1500mg daily for 17 days, failed to produce a statistically significant effect with regards to erectile dysfunction as compared to the placebo.

In a 2003 study, researchers investigated the effects of increased NO on erectile dysfunction using two alleged NO increasing substances: l-arginine (1.7 grams daily) and Pycnogenol. During the first month, subjects only received arginine and only 5% reported improved symptoms of erectile dysfunction. During the second month, subjects received 80mg Pycnogenol daily in addition to the arginine, and 80% reported improvement. During the third month, the dose of Pycnogenol was increased by 40mg to 120mg and 92.5% of the subjects reported experiencing normal erections. While the researchers concluded that a combination of arginine and Pycnogenol was an effective alternative treatment for erectile dysfunction, it is important to note the arginine by itself was ineffective.

It wasn’t until the addition of Pycnogenol that subjects showed significant improvement. As evidenced by the previously mentioned study, it appears as though low doses of arginine (1.5 or 1.7 grams) are not significantly effective at treating erectile dysfunction. Furthermore, the evidence suggests that large doses (5 grams) may only be effective in individuals with low NO levels.

MACA

Maca (Lepidium Meyenii) is a relative of broccoli, indigenous to Peru, which has historically been used as an aphrodisiac. While frequently included in products aimed at increasing testosterone, research has confirmed that the aphrodisiac effect of Maca is not caused by an elevation of testosterone, nor does it have any significant impact on any hormones.

In several human studies, Maca has demonstrated a clear aphrodisiac effect when at least 1.5 grams is consumed. A 2009 study using 2400mg of Maca showed “a small but significant effect of Maca supplementation on subjective perception of general and sexual well-being in adult patients with mild ED.” A separate 2009 pilot study, this time investigating a potential effect on physical performance, found that Maca supplementation effectively improved physical performance (cycling) in trained male cyclists, while simultaneously increasing sexual desires.

Overall, it appears Maca supplementation with atleast 1.5 grams may increase sexual well-being and possibly improve certain aspects of physical performance. However, given that the VeinERECT formula contains only 500mg of Maca per serving, the degree of efficacy cannot be certain.

THE BOTTOM LINE

VeinERECT contains only two ingredients: Arginine and Maca, both of which have demonstrated varying degrees of efficacy as alternative treatments for erectile dysfunction. However, the individual doses present in the formula have not been evaluated, and any efficacy was demonstrated using higher doses of each. Even at double the dose, Arginine may only be an effective ED treatment in individuals with low nitric oxide. In order to achieve the minimum substantiated dose of Maca, three servings would have to be consumed. At a price of about 50 cents per serving, VeinERECT is charging a hefty premium, considering the same formula could be reconstructed for less than half the price by buying the ingredients separately.
