L-Arginine

As another essential amino acid, L-Arginine is important in our sex lives, not least because it compromises 80% of the sperm cells!

A deficiency may result in impotence, sterility, and decrease in the production and mobility of sperm. L-Arginine is also important for the synthesis and release of the pituitary gland's growth hormone. A L-Arginine supplement can increase sperm counts and is essential for adults after the age of 30 when there is almost a complete cessation of its secretion from the pituitary gland.

It acts by increasing the amount of nitrous oxide in the body which signal the penis to expand and leads to longer lasting and quicker erections.
