D-mannose is a relation of glucose and contains just one sugar molecule which makes it a simple sugar. We produce D-mannose in very small amounts within the human body but supplements like this make it viable for our bodies to obtain larger quantities. D-mannose is also available in powder format but many people prefer these coated tablets as they are easier to take when you are not at home. D-mannose can be found in fruit like cranberries.
