I bought these cranberry pills after semi-frequent visits to the doctor for bladder infections, at the recommendation of my doctor.
I don't take it every day, I only take it when I can start or think I maybe on the onset of an infection.
They work, I take as directed on the bottle and continue use for a few days. Usually on day 2 the infection has subsided and does not develop any further. Since I have been using this, I haven't been back to the doctor for an infection at all! Try it, it works and its cost effective!
