- Description: A meta-analysis of 18 cohort and case-control studies covering 103,658 subjects tied vitamin C intake to lower prostate cancer risk, with 150 mg a day linked to 20% lower risk in case-control data. A 1997 lab study found vitamin C slowed prostate cancer cell growth.

Thursday Nov 26, 2015 (foodconsumer.org) -- A meta-analysis of data from 18 cohort and case-control studies suggests that intake of vitamin C may reduce risk of prostate cancer. A study of the data from case-control studies finds that those who had 150 mg of vitamin C per day (which is fairly low) were 20% less likely to develop prostate cancer. Vitamin C is also known as ascorbic acid.

Another study of two lines of prostate cancer cells (androgen independent and androgen dependent) shows that vitamin C can inhibit cell division and growth of prostate cancer cells. This inhibition was found due to hydrogen peroxide produced from vitamin C. The inhibition was dose and time dependent.
