23 years of documented vitamin safety

A 23-year review of US poison control center annual reports tells a remarkable and largely ignored story: vitamins are extraordinarily safe. Annual deaths alleged from vitamins:

2005: zero
2004: two
2003: two
2002: one
2001: zero
2000: zero
1999: zero
1998: zero
1997: zero
1996: zero
1995: zero
1994: zero
1993: one
1992: zero
1991: two
1990: one
1989: zero
1988: zero
1987: one
1986: zero
1985: zero
1984: zero
1983: zero

The zeros are not due to a lack of reporting. The American Association of Poison Control Centers (AAPCC), which maintains the USA's national database of information from 61 poison control centers, has noted that vitamins are among the 16 most reported substances. Even including intentional and accidental misuse, the number of alleged vitamin fatalities is strikingly low, averaging less than one death per year for more than two decades. In 16 of those 23 years, AAPCC reports that there was not one single death due to vitamins.

Minerals, which are chemically and nutritionally different from vitamins, have an excellent safety record as well, but not quite as good as vitamins. On the average, one or two fatalities per year are typically attributed to iron poisoning from gross overdosing on supplemental iron. Deaths attributed to other supplemental minerals are very rare. Even iron, although not as safe as vitamins, accounts for fewer deaths than do laundry and dishwashing detergents.
