DHEA is a steroid hormone produced by the adrenal glands. It is called the "Mother Hormone" because it can be converted to other vital hormones, such as estrogen, testosterone, progesterone, etc.* Levels of DHEA drop off dramatically after age 30, and scientists feel this may be one of the reasons for aging.* DHEA is involved in a variety of health areas and it is recommended that testing for DHEA levels be performed before it is administered.* Our DHEA is in a 98.5% pure form.
