Urinary Tract Infection

A urinary tract infection happens when bacteria, most often E. coli, cling to the lining of the bladder and multiply, causing burning, urgency and sometimes reaching the kidneys. Cranberry and D-mannose are the supplements most often discussed for keeping bacteria from sticking to the bladder wall, but little research on them has been reviewed here so far. Until more studies are added, it is too early to say how well any supplement works.
