A popular alternative health remedy, D-Mannose is touted to be a reliever of many ailments of the urinary tract, including urinary tract infections. How truthful are these claims, and is D-Mannose right for you? What are the side effects?
What is D-Mannose?
Related to glucose, D-Mannose is a simple sugar that is slowly absorbed in the GI (gastrointestinal) tract. Much of it is excreted upon urinating.
Blueberries, cranberries, and oranges are just some of the fruits that are sources of D-Mannose. Apples are another good source.
D-Mannose is primarily used for UTIs, or urinary tract infections. However, there is little to support this in clinical research.
Typical doses start at 2.5ml to 5ml (or half to one teaspoon) of the powder form in water every two to three hours during the waking hours.It also comes in capsule form and is available at some health food and supplement shops.
