L-Arginine 500mg

For an erection to occur, the nerves in the penis need to make a chemical called Nitric oxide. Nitric acid is the substance in the body that encourages the spongy parts of the penis to fill with blood during an erection. Because the chemical reaction in the body creates Ntiric oxide from L-Arginine, supplementing with L-Arginine is believed to help stimulate and maintain erections.

L-Arginine is also involved in the production of sperm and is an extremely rich component of seminal fluid (accounting for up to 80% of it). This is a daily supplement, so it should be taken on a long-term basis to feel the full benefits.
