Looking to buy D-Manosse From Boots.com . I came across some articles about D-Mannose a few days ago and since then I have been researching about them. From whatever I have read up, I have found that D-Mannose is a simple sugar that helps to treat Cystitis. It achieves that by attaching itself to them and then flushing itself out. It is supposedly very simple and safe with none of the side effects that antibiotics might have. Also, it is stronger than the more popular alternative of cranberry juice. So my question is, has anyone tried this? The bottle isn’t cheap and though I want to try it, I wasn’t some kind of reassurance at least that I am not throwing my money down the drain.
