DHEA is a hormone. In the human body, DHEA is mostly produced by the adrenal glands (small glands that sit above the kidneys). Researchers are not exactly sure what DHEA itself does, although it is known that the body transforms DHEA into other steroid hormones, such as testosterone and estrogen. It is difficult to predict to what extent the body will convert DHEA into testosterone or estrogen in any particular individual. Some people will convert DHEA mostly into testosterone, while others will mostly convert it into estrogen.
Children may be more susceptible to the side effects and toxicities of drugs and supplements, including DHEA. Do not give your child DHEA supplements without the approval of your child's healthcare provider. It is not a good idea to alter the hormone balance in your child without the careful supervision of your child's healthcare provider.
