Supplements: The 'commonly' taken vitamin that can prove 'fatal' – NHS issues warning


Supplement use was self-reported in 1986, 1997, and 2004. Through December 31, 2008, a total of 15, 594 deaths were identified through the State Health Registry of Iowa and the National Death Index.

The use of multivitamins, vitamin B6, folic acid, iron, magnesium, zinc, and copper were associated with increased risk of total mortality when compared with corresponding nonuse.

“In older women, several commonly used dietary vitamin and mineral supplements may be associated with increased total mortality risk; this association is strongest with supplemental iron,” the researchers observed.

What does the Department of Health and Social Care (DHSC) advise?

“Most people should be able to get all the iron they need by eating a varied and balanced diet.”
