Aging brings a steady decline of Dehydroepiandrosterone (DHEA), the body's most-abundant corticosteroid hormone. By 80, levels can fall to just 5% of those at age 20. DHEA helps to convert to—or stimulate the production of—estrogen, testosterone, cortisone, and other steroid hormones as needed. 

Additionally, some cells have specific DHEA receptor sites. Research suggests that DHEA supports the maintenance of normal adrenal and immune function,bone density, healthy skin, and sexual health.* Karuna's DHEA contains biochemically pure DHEA in amounts suitable for flexible dosing. Karuna does not use wild yam or other sources claiming to contain "natural" DHEA precursors, because studies demonstrate these precursors cannot be activated in the human body.
