DHEA (Dehydroepiandrosterone) is a pharmaceutical grade, purified supplement. This micronized form is designed to increase its bioavailability when compared to the standard form. DHEA is a naturally occurring androgen secreted by the adrenal glands, and is found in plasma and brain tissue. Do NOT take DHEA if you are at risk for hormonally related cancers such as reproductive or prostate abnormalities, if under the age of 40, or if pregnant, lactating or trying to conceive.
