Cranberry is a small, evergreen shrub grown throughout North America and the juice from its berries has a long history of use among native American Indian tribes, primarily for treating urinary conditions.
One of the simple sugar molecules found in cranberries is d-mannose, which helps prevent urinary tract infections (UTIs) as well as carbohydrate-deficient glycoprotein syndrome, which is an inherited metabolic disorder.
And while cranberry juice – as well as pineapple juice – contain more d-mannose than most other foods, the amounts found in them are substantially less than the recommended half teaspoon (approximately 1 gram) adult dose.
This mean that taking d-mannose in tablet form makes a lot of sense – and especially when you consider that having the supplement can also improve protein loss, liver function, low blood sugar and blood clotting disorders in people with that condition.
D-mannose is very safe, even for long term use, and although it’s a simple sugar very little of it is metabolised. It doesn’t interfere with blood sugar regulation, even for diabetics; and it creates no disruption or imbalance in normal body microflora.
