Last year the news created headlines referring to research stating that multivitamins increased the risk of dying. This did not make any sense and now recent research has disputed that.
The reviewed study analyzed 21 articles and included 91,074 people and 8,794 deaths (Macpherson H, et al. 2012). The average age of the participants were 62 years, and the duration of supplementation was 43 months.
No effect of multivitamin-mineral use on all-cause mortality was observed. There was however a trend for a reduced risk of all-cause mortality across primary prevention trials.
According to this study you can safely take your multivitamins, it may actually do you some good.
