Jarrow Formulas 7-Keto DHEA is a naturally occurring metabolite of DHEA. It is unable to metabolize into sex hormones; therefore, it can provide many of the same benefits of DHEA without its associated side effects. In the body, 7-Keto DHEA is responsible for activating enzymes responsible for fatty acid and carbohydrate metabolism. The body's production of 7-Keto DHEA declines with age, which is directly correlated with a decline on metabolic rate. Clinical studies of 7-Keto DHEA demonstrated increases in metabolic rate and improvement in body mass index.
