7-Keto-DHEA is a natural metabolite of Dehydroepiandrosterone (DHEA) whose level in the body declines with age. Its decline is often accompanied with a decrease in metabolic rate. However, unlike DHEA, 7-Keto-DHEA does not convert to estrogen or testosterone. 7-KETO&ampreg; is a patented ingredient that has been shown, in clinical studies, to assist in the maintenance of a healthy body weight and helps to maximize results of a proper diet and exercise. In addition to 7-Keto-DHEA, NOW&ampreg; 7-KETO&ampreg; LeanGels&amptrade;, includes a special healthy metabolism blend consisting of Green Tea Extract, Acetyl-L-Carnitine and Rhodiola Extract to support cellular fat transport and antioxidant systems.*
