D-mannose, also known as mannose, is a naturally occurring simple sugar that is related to glucose. It's found in many fruits and vegetables, including cranberry, black and red currants, peaches, green beans, oranges, mangoes, cabbage, and tomatoes. It also naturally occurs in the human body; however many people find it useful to take a supplement to ensure that they are getting adequate levels of the sugar. These supplements often come in capsules, gummies, tablets, pills, effervescent, liquid, sachets, or powder formats; and often found in complex formats with cranberry. To use D-mannose powder, dissolve it in a glass of liquid and then drink the mixture. The powder is easily dissolvable and unflavoured therefore can be added to your favourite drink without compromising its taste.
