This certified organic D-Mannose powder will meet the discriminating needs of the health and environmentally-conscious consumer. D-Mannose is a simple sugar that occurs naturally in some plants, including cranberries and other fruits. Although small amounts of D-Mannose are metabolized by the human body, much of it is rapidly excreted in the urine. In the bladder, D-Mannose may adhere to undesirable foreign substances, preventing them from sticking to the lining of the bladder helping to reduce the risk of recurrent UTI’s.
