7-Keto is a natural occurring metabolite of DHEA, providing the same benefits of DHEA, without its associated side effects. Because the body's production of DHEA declines with age, so does the production of 7-Keto. Weight gain is a common sign of aging that often accompanies the decreased production of DHEA and its metabolites. Supplementation with NOW 7-Keto can safely promote thermogenesis, thereby supporting the maintenance of healthy body weight.
