DHEA (Dehydroepiandrosterone) is a hormone produced by the adrenal glands. As you age, DHEA levels decline significantly. DHEA peaks around age 20 and then decreases by about 10% per decade. By the time you reach your 70s or 80s, DHEA levels may be only 10% to 20% of their peak. DHEA supplements are available in oral and topical forms. Some people believe it can slow the aging process, but there's not enough evidence to support these claims. Studies suggest DHEA may help with conditions like osteoporosis and depression, but more high-quality clinical trials are needed to confirm these benefits. DHEA can convert into estrogen and testosterone, potentially impacting bone density, depression symptoms, and sexual health, but effects vary from person to person. DHEA supplementation can also cause side effects like liver problems and hormonal changes. If you're considering DHEA supplements, it's advisable to consult a doctor first.
