DHEA (dehydroepiandrosterone) is a hormone produced by your adrenal gland. These are the glands above your kidneys
DHEA supplements can be made from wild yams or soybeans.
Scientists do not know everything about DHEA. But they know it is the predecessor of male and female sex hormones, including testosterone and estrogen. A precursor is a substance that is converted into a hormone by the body.
DHEA production peak in the mid-1920s. In the eyes of most people, with the growth of age, production gradually decreased.
