D-Mannose is a naturally available sugar compound that is a practical and safe substitute for common sugar, and is used to treat urinary tract infections. It is much slower in absorption than glucose, does not convert to glycogen when ingested, and is not stocked up in liver. It goes to bloodstream directly, from the higher GI tract. Thus, D-Mannose is strained through the kidneys and sent to the bladder. It helps to promote and support a healthy urinary tract and bladder. It is completely safe, as it does not kill any cells; rather it attracts the displaced e-coli and covers the bladder wall.
