DHEA (Dehydroepiandrosterone) is a natural hormone produced by the adrenal glands, the brain and the skin, and is the most abundant hormone in the body. As middle age approaches the production of DHEA slows, and scientific evidence shows a direct link of DHEA deficiency to various problems associated with the aging process. DHEA is produced in abundance during youth, peaking at about age 25, with production slowing thereafter. By age 80 it is believed that people have only 10 to 20 percent of the DHEA they had at age 20. *
