Answer

Almost 60,000 instances of vitamin toxicity are reported annually to US poison control centers. [1, 2] According to National Health and Nutrition Examination Survey (NHANES) data, in 2003–2006 33% of the United States population aged 1 year and older took a multivitamin supplement in a given month. [3] In a 2009 survey, 56% of US consumers said they take vitamins or supplements, with 44% saying they take them daily. [4] (See Pathophysiology and Etiology.)
