Dietary Supplement. Supports Longevity. HPLC Tested for Potency and Purity. DHEA (Dehydroepiandrosterone) is produced in the adrenal glands from pregnenolone and converts into testosterone, estrone and estradiol. As we age, our DHEA levels decrease which could be pivotal to overall health status. DHEA supplementation has shown the ability to return circulating DHEA concentrations to those experienced in younger years. Contains no common allergens (e.g. no gluten or soy) or artificial colors.
