signpost iconLycopene for the prevention of prostate cancer

Bottom Line:

Given that only three RCTs were included in this systematic review, and the high risk of bias in two of the three studies, there is insufficient evidence to either support, or refute, the use of lycopene for the prevention of prostate cancer.

Publication details:

This systematic review looked at whether lycopene reduces the incidence of prostate cancer and prostate cancer-specific mortality.
