Dehydroepiandrosterone (DHEA)
Introduction
Dehydroepiandrosterone (DHEA) is a steroid produced by the adrenal gland and is a precursor ofestrogensand androgens. Effects on the body are similar to those oftestosterone. DHEA can also be synthesized from precursors in the wild Mexican yam; this form is the most commonly available. However, consumption of wild yam is not recommended as a supplement as the body is unable to convert the precursors to DHEA. (See also Overview of Dietary Supplements .)
