Normally, L-arginine is considered to be a non-essential amino acid, but under certain conditions it may become 'conditionally-essential,' which means that additional L-arginine must be extracted from the diet.

In 1988 researchers discovered that L-arginine's wide-ranging health benefits were due primarily to its role as a precursor to nitric oxide (NO). L-arginine stimulates the release of nitric oxide from the walls of blood vessels, helping them naturally expand to promote healthy circulation. So L-arginine is a particularly important amino acid for overall circulatory health.

L-arginine has been found to be particularly helpful for invigorating male sexual performance by enhancing healthy blood flow to the penis. L-arginine also works in another way to stimulate erectile function. Nitric oxide is produced in response to arousal messages from the brain. It triggers the release of a compound that causes the smooth muscles of the spongy tissues inside the penis to relax, allowing the tissue to engorge with blood. Both these processes require L-arginine to stimulate the release of nitric oxide to promote healthy erectile function.

L-Arginine helps the body:

• Promote healthy erectile function
• Enhance circulation throughout the body
