Oncovite was "developed" by a urologist and supposedly the vitamins in it are to support a healthy bladder lining. Bladder 2.2 is a similar formulation. They are both similar in design, if not content, to Ocuvite which is promoted for eye health.
Basically they are fairly potent, and quite expensive, vitamin pills. My urologist's advice..."well, it probably can't hurt. but it certainally it is not a treatment for bladder cancer.
