Hoodia gordonii, a 20:1 concentrate from South Africa, is synergistically mixed with Glucomannan to provide a potent dual action affect. Hoodia has been used for centuries in the Kalahari Desert to help hunters endure long expeditions. Our Hoodia comes directly from a South African grower who is certified to export this product under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Our Hoodia is grown for two to three years to provide peak potency. No fillers or excipients are used in our product.
