What we have so far
35,000 men on vitamin E and selenium for prostate cancer. It stopped early, and on longer follow-up the vitamin E arm had MORE cancer — 17% more.
This star is on the map because the show intends to take the question apart properly — the trials, how it is actually tested, whether the thing sold is the thing studied. That work is not done yet, and nothing here should be read as a conclusion. When the investigation is published it will appear on this page.
