Dehydroepiandrosterone (DHEA) is a hormone that comes from the adrenal gland. It is also made in the brain. DHEA leads to the production of androgens and estrogens (male and female sex hormones).

Lower DHEA levels are found in people with hormonal disorders, HIV/AIDS, Alzheimer's disease, heart disease, depression, diabetes, inflammation, immune disorders, and osteoporosis.
