This editorial published in the Annals of Internal Medicine, and titled, Enough Is Enough: Stop Wasting Money on Vitamin and Mineral Supplements, makes the point that studies show that there is no clear evidence of a beneficial effect of supplements on all-cause mortality, cardiovascular disease, or cancer, that a study conducted for 12 years, found no differences between the multivitamin and placebo groups in overall cognitive performance or verbal memory, and a study evaluating the potential benefits of a high-dose, 28-component multivitamin supplement with a previous heart attack, found that there was no significant difference in recurrent cardiovascular events with multivitamins compared with placebo.
The authors conclude:
Although available evidence does not rule out small benefits or harms or large benefits or harms in a small subgroup of the population, we believe that the case is closed— supplementing the diet of well-nourished adults with (most) mineral or vitamin supplements has no clear benefit and might even be harmful. These vitamins should not be used for chronic disease prevention. Enough is enough.
