d-Mannose is a simple sugar found naturally in cranberries and pineapples. It is metabolized in small amounts, the remainder of which is excreted via the urine. As it is flushed out of the body, d-mannose maintains a healthy environment for the mucosal surface of the urinary tract.
Pure Encapsulations recommends 1/2 teaspoon 3 times per day, mixed with water, with or between meals. Each container of d-mannose provides a 1/2-teaspoon scoop.
