Selenium and CoQ10 extend life

Every cell in the body needs selenium to function properly, and CoQ10 helps each cell produce energy. In this study, 668 healthy older adults took 200 mcg of selenium plus 200 mg of CoQ10 per day, a placebo, or no treatment.

Doctors divided each of the three groups into low, medium, and high selenium based on how many micrograms of selenium per liter of blood they had at the start of the study. In the group starting with the lowest circulating levels of selenium, those taking selenium supplements were 12 percent less likely to die from heart disease over the four-year study period compared to placebo or no treatment. In the middle-selenium group, chances were 8 percent lower in the selenium supplement group, and in the high-selenium group, chances were 4.5 percent lower for those taking selenium supplements.
