So I get about 2 UTI's a year which have recently been caused by klebsiella Pneumonia. Most recently, my urine culture came back positive for 10k colony forming units which is basically the beginnings of a UTI but not considered clinically significant enough to warrant an antibiotic although my typical UTI symptoms were present. So since my doctor refused to prescribe anything, I decided to try to tackle this on my own using these cranberry d-mannose gummies. I started taking 8 gummies a day (4 in the morning and 4 at night) for 5 days and requested another culture and when those results came back, they were negative and indicated 'no growth.' So either my immune system kicked in or these gummies worked. Given that my immune system rarely kicks in to keep me UTI free, I think it's safe to assume it was the Nature's Way gummies
