Although DHEA has received a lot of press for its potential ability to slow the aging process, 7-keto DHEA has recently come into the limelight. Scientists now believe it may provide all the benefits of DHEA without the potential side effects of its popular predecessor. Because 7-keto DHEA cannot trigger potentially dangerous levels of estrogen and testosterone in the body— which can occur in some patients who use DHEA—scientists now think 7-keto DHEA may be a safer alternative.

Human production of DHEA normally peaks during our mid-20's and then begins a steady, progressive decline. DHEA is only produced in the bodies of humans and other primates such as monkeys and apes. There are no good dietary sources of DHEA other than by way of supplementation.

7-keto DHEA has also been studied for its potential immune-boosting properties. Researchers think that it may stimulate the activity and effectiveness of crucial immune system components known as T-lymphocytes. These T-lymphocytes may in turn stimulate additional immune system functions.(3) Studies based on these observations suggest that 7-keto DHEA may have a future as an important immune system enhancer.(4)(5) Thus, 7-keto DHEA could prove to be therapeutically useful in a wide range of conditions, including major killers such as cancer. Studies also suggest that DHEA may reduce the replication of the HIV virus, making it a potential weapon in the fight against the AIDS virus.(6)

Lastly, 7-keto DHEA may positively influence thyroid function and metabolism.(7) Scientists believe that 7-keto DHEA's support of thyroid function may help patients reduce body weight and body fat. In fact, one clinical study of patients who took 7-keto DHEA seems to support the hypothesis that the supplement can enhance weight loss.(8)
