SELECT trial

The SELECT trial was a major medical study aimed at understanding the relationship between selenium and vitamin E supplements and prostate cancer risk. Conducted from 2001 to 2014, it involved thousands of men who were given either these supplements or a placebo. The findings showed that taking vitamin E increased the risk of prostate cancer, while selenium did not significantly affect cancer rates. This trial emphasized the need for caution regarding dietary supplements and highlighted the importance of conducting rigorous scientific research to guide health decisions.
