Does D-Mannose always help for bladder infections or cystitis?
D-Mannose has been found to be beneficial in cases of bladder infections caused by urinary bacterial infections of E.Coli (which is thought to be the cause of around 85% of cases) and a couple of other rarer bacteria, so for most people it will be very helpful. It may not work as well for interstitial cystitis, although some early reports from researchers suggest that it may help after a longer period of time, perhaps because there are mannose receptors in the bladder wall, but it is unclear why this is.
