Over a twenty-seven year period, vitamin supplements have been alleged to have caused the deaths of a total of eleven people in the United States. A new analysis of US poison control center annual report data indicates that there have, in fact, been no deaths whatsoever from vitamins . . . none at all, in the 27 years that such reports have been available.
The American Association of Poison Control Centers (AAPCC) attributes annual deaths to vitamins as:
Still, the Orthomolecular Medicine News Service Editorial Board was curious: Did eleven people really die from vitamins? And if so, how?
Vitamins Not 'THE' Cause of Death
In determining cause of death, AAPCC uses a four-point scale called Relative Contribution to Fatality (RCF). A rating of 1 means "Undoubtedly Responsible"; 2 means "Probably Responsible"; 3 means "Contributory"; and 4 means "Probably Not Responsible." In examining poison control data for the year 2006, listing one vitamin death, it was seen that the vitamin's Relative Contribution to Fatality (RCF) was a 4. Since a score of "4" means "Probably Not Responsible," it quite negates the claim that a person died from a vitamin in 2006.
Vitamins Not 'A' Cause of Death
In the other seven years reporting one or more of the remaining ten alleged vitamin fatalities, studying the AAPCC reports reveals an absence of any RCF rating for vitamins in any of those years. If there is no Relative Contribution to Fatality at all, then the substance did not contribute to death at all.
Furthermore, in each of those remaining seven years, there is no substantiation provided to demonstrate that any vitamin was a cause of death.
If there is insufficient information about the cause of death to make a clear-cut declaration of cause, then subsequent assertions that vitamins cause deaths are not evidence-based. Although vitamin supplements have often been blamed for causing fatalities, there is no evidence to back up this allegation.
