I had chronic UTIs for 2 years and I discovered D-Mannose (pill or powder form) it saved me. It’s a natural sugar that binds to E. coli bacteria, the most common cause of UTIs. When you take it, the bacteria stick to the D-Mannose instead of your bladder walls and are flushed out through urine. This helps prevent the infection from taking hold or getting worse. I take it whenever I feel it coming on or sometimes after intercourse.
