7-Keto is a naturally occurring metabolite of DHEA that does not affect hormone levels, but is known for its anti-aging properties. Because the body's production of DHEA declines with age, so does the production of 7-keto-DHEA. Weight gain is a common sign of aging that often accompanies the decreased production of DHEA and its metabolites. 7-KETO&ampreg; has been patented for its ability to promote thermogenesis as well as for the maintenance of healthy body weight.*
