Hello @ksey. I am an RN and female. Years ago when I had frequent UTI's one thing I did was always urinate after intercourse. My husband has also been plagued with UTI's and after I read everything I could find about them I came across D-Mannose. After he started taking it DAILY, either capsules or sprinkling about a teaspoon of D-Mannose on his cereal or drinking a teaspoon of the powder in a non -acidic liquid he has had only about one UTI or less per year!!! It is a simple sugar that prevents bacteria from "sticking" to the bladder wall. He also takes Cranberry capsules (he doesn't like the juice!) You may need it 3 times a day to start with. We order ours from Swanson. Several other Mayo Connect members have found D-Mannose to help them immensely! I truly hope this is helpful.
