Resveratrol better than Viagra?

Resveratrol Better Than Viagra

October 14th, 2009 – Drugs like Viagra (Sildenafil citrate) and Cialis (Tadalafil) are used to treat erectile dysfunction (ED) by increasing blood flow to the erectile tissue in the penis known as the corpus cavernosum.

These drugs increase blood flow to erectile tissue by inhibiting the phosphodiesterase enzymes (PDE5 & 6), which prolongs the action of cGMP in the smooth muscle tissue, increasing the dilation response from nitric oxide (NO) release. However, inhibition of the phosphodiesterase enzyme system has effects across the entire body and can lead to side-effects including headache, skin flushing, nasal congestion and muscle aches. (1) These are very unwelcome side-effects when trying to stimulate sexual arousal.

New research suggests that resveratrol can also trigger erections by promoting blood flow to the erectile tissue in the penis. (2) This vasodilatory effect appears to occur within minutes of resveratrol exposure, suggesting that supplementation may provide a quick temporary boost in sexual performance. (3)

Evidence suggests that resveratrol does not have the side-effects typically associated with popular ED drugs. Resveratrol improves vasodilation by multiple cellular mechanisms, and does not negatively inhibit the phosphodiesterase enzyme system, which can lead to unwanted side-effects. (3) Whether or not resveratrol is a worthy substitute to powerful prescription drugs such as Viagra and Cialis remains to be determined.
