Soy Isoflavones (genistein, daidzein)

who were followed for three years or longer. [Cancer Epidemiol Biomarkers Prev 2002;11(12): pp.1674-7]

Vitamin E
Ten years of regular supplemental vitamin E intake, but not regular use of shorter duration was associated with a reduced risk of bladder cancer mortality in a study of 991,522 adults in the United States. [Am J Epidemiol 2002;156(11): pp.1002-10]

Vitamin C (Ascorbic Acid)
In a very large study, the regular supplementation with vitamin C was not associated with the risk of bladder cancer mortality.
