Horny Goat Weed Extract: Horny Goat Weed has testosterone-like effects stimulating sexual activity, increases sperm production and stimulates sensory nerves. A 2008 lab study found that horny goat weed contains a compound called Icariin, which helps to block the effects of an enzyme responsible for restricting the quantity of blood flow into the sexual organs. Icariin appears to act as a phosphodiesterase inhibitor (inhibits PDE-5 enzyme), which then raises the nitric oxide levels to support erectile function and performance similar to the action of Viagra.
Passion Flower Extract: Passion Flower is known to ease the feeling of stress, anxiety, and tension. It has a soothing and mildly sedative effect, which helps to relax your mind and body, thus promoting increased sexual performance.
Longjack Extract (Tongkat Alie): Longjack has been used for men and women as a natural sexual performance aid, general health tonic, and aphrodisiac.
Guarana Extract: Guarana is well known for its powerful effect of increased vigilance and reduced fatigue in that it contains 4-5 times more caffeine (called guaranine) than coffee; thereby providing the stamina, endurance, and energy to enhance sexual performance.
Ginseng Extract: The Maryland University Medical Center suggests that Ginseng may improve libido, or sexual interest. Ginseng’s exact relationship with sex drive is not well understood, but it is believed to work by enabling the body to adapt to stress with fewer fluctuations in sex drive. According to the National Institutes of Health, Ginseng can reduce the symptoms of erectile dysfunction, or male impotence. Men taking Ginseng may have firmer, longer-lasting erections that are easier to attain.
Maca Extract: Maca's fertility-boosting properties, on the other hand, have been attributed to its glucosinolate levels, which are similar to those of horny goat weed, another plant known to aid sexual health. L-Theanine: Many men take L-Theanine to overcome social and approach anxiety, and talk to women, and for reducing performance anxiety. It does this by lowering the cortisol levels and increasing the alpha waves in your brain, which relaxes the body and mind.
