DHEA
DHEA (Dehydroepiandrosterone) is a naturally occurring substance that is changed in the body to the hormones estrogen and testosterone. It is also manufactured and sold as a dietary supplement.
A few small studies have suggested that DHEA might possibly have some benefit for hot flashes and decreased sexual arousal, although small randomized controlled trials have shown no benefit. Because levels of natural DHEA in the body decline with age, some people believe that taking a DHEA supplement can help treat or prevent conditions related to aging; however, there is no good scientific evidence to support this notion.
Concerns have been raised about whether DHEA is safe and effective. Its long-term effects, risks, and benefits have not been well studied, and scientists are not certain whether it might increase the risk for breast or prostate cancer. Before using DHEA for any purpose, people should talk to their health care provider about potential benefits and risks.
