How many of us yearn to turn back the hands of time and halt the ravages of aging? Several researchers claim that they have discovered a way to do just that. A hormone called DHEA (dehydroepiandrosterone), which is produced by the adrenal glands, is now available without a prescription. In DHEA: A Practical Guide, Dr. Sahelian discusses the safety of DHEA, how DHEA affects the brain, heart and immune system, DHEA levels throughout life, and what is known about DHEA's anti-ageing potential. He covers, in-depth, the practical aspects of how much to take and when, and even includes personal stories of DHEA users.
