DHEA (dehydroepiandrosterone) is a hormone that’s naturally produced by the adrenal glands. Levels of DHEA naturally drop after age 30. Some people take DHEA supplements in the hopes that DHEA will have health benefits and prevent some illnesses. However, the evidence is mixed.
DHEA is used by some people who want to “reverse” aging and boost immunity, cognitive function, and muscle strength. For now, studies don’t back up these uses. DHEA has been studied as a treatment for other conditions, ranging from cardiovascular disease to menopause to Alzheimer’s. The results have been unclear.
