"The number of areas where supplemental DHEA is helpful is almost alarming, because it covers such a broad range of diseases. DHEA is taken by mouth, and when blood levels of DHEA are increased to the level you had at a younger age, many diseases just melt away. The body seems fully capable of using supplemental DHEA, as if it were processed in the body.
Dr. Norman Applezweig, New York Biochemist
"DHEA is the motherload for some 18 different steroidal hormones integral to eternal youth. Unlike hormones that excite cells into activity, DHEA "de-excites" the body's processes. Some of the diseases of aging are caused by the runaway production of nucleic acids, fats and hormones, DHEA slows down their production and thereby slows down aging."
Dr. Arthur Schwartz, Temple University
"DHEA prolongs life and adds"quality": to those extra years. When DHEA was fed to mice, it increased their life expectancy from 24 to 36 months, which is the equivalent of 35 to 40 human years. The mice seemed younger and had a lower incidence of many of the traditional diseases of aging than mice on regular basis. "It reduces the risk of developing breast, colon, and lung cancer in the mice. Other studies have found DHEA can reduce the risk of developing cancer of the liver, skin and lymphatic tissues." DHEA appears to be the first substance that allows animals to lose weight without changing their eating habits. The calories they consume are converted to heat rather than fat, thereby allowing the animals to lose weight. In fact, a 1977 study by Trench T. Yen, a biochemist at Eli Lilly in Indianapolis, found that when DHEA is fed to obese mice, their weight dropped significantly. DHEA seems to increase the body's ability to transform food to energy -- a process that enables the body to " burn off" excess fat but also prevent fat from accumulating in the first place."

Harvard Health letter "DHEA GETS RESPECT", Dr. Daynes reports adding DHEA to vaccines helped older mice produce the same vigorous antibody response as young mice. Richard Hodes, who leads the National Institute on Aging call the results "extremely interesting and potentially important."

"In a study of 242 men over the age of 50, it was found that those with high level of DHEA in their blood were only half as likely to die of heart disease as those with relatively little of the hormone. Even with people without heart disease, DHEA seems to protect against early death. On its own, that's good news. But coming as it does after reports that taking DHEA can prevent or ease a variety of other illnesses, it may be the strongest evidence yet that a single hormone plays a contrast role in maintaining human health."
