D-Mannose is a simple sugar present in cranberries and other fruits. Taken as a supplement, it stops certain bacteria, especially E. Coli, from sticking to the bladder wall. The bacteria get flushed out when you urinate.
Many people take D-Mannose at the earliest sign of urinary discomfort or when they feel more vulnerable to urinary tract issues. Standard daily doses fall between 1,000 mg and 3,000 mg, split into smaller servings.
For best absorption, take D-Mannose on an empty stomach. Powder and capsules are the most common forms. High doses sometimes cause loose stools or an upset stomach. Anyone with diabetes should check blood sugar levels closely. D-Mannose does not replace antibiotics for a confirmed infection. See a doctor if symptoms don't improve.
