The Claim
High-dose vitamin E supplementation increases the incidence of prostate cancer in healthy men.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking high doses of vitamin E supplements raises the number of prostate cancer cases in men without pre-existing cancer.
See the scientific wording
High-dose vitamin E supplementation increases prostate cancer incidence in healthy men.
High doses of vitamin E overwhelm the body's natural antioxidant systems, causing a shift in chemical balance that damages DNA in prostate cells. This damage accumulates over time and leads to abnormal cell growth that becomes prostate cancer.
What the research says
2 studiesStudy: Vitamin E and selenium do not decrease prostate cancer incidence: vitamin E may actually increase it
This study found that men who took a daily vitamin E pill (400 IU) were 17% more likely to get prostate cancer than men who took a sugar pill. So yes, taking high doses of vitamin E supplements appears to raise the risk of prostate cancer.
Study: Prostate cancer: Vitamin E and prostate cancer—what is the real risk?
In a study of healthy men, those who took vitamin E supplements were slightly more likely to be diagnosed with prostate cancer than those who took a placebo. This suggests that taking high doses of vitamin E might increase the chance of getting prostate cancer.
