===Excess intake===
{{See also|Hypervitaminosis}}

Some vitamins have documented acute or chronic toxicity at larger intakes, which is referred to as hypertoxicity. The European Union and the governments of several countries have established [[Tolerable upper intake levels]] (ULs) for those vitamins which have documented toxicity (see table).<ref name="DRITable" /><ref name="EFSA" /><ref name="JapanDRI" /> The likelihood of consuming too much of any vitamin from food is remote, but excessive intake ([[vitamin poisoning]]) from dietary supplements does occur. In 2016, overdose exposure to all formulations of vitamins and multi-vitamin/mineral formulations was reported by 63,931 individuals to the [[American Association of Poison Control Centers]] with 72% of these exposures in children under the age of five.<ref>{{cite journal | vauthors = Gummin DD, Mowry JB, Spyker DA, Brooks DE, Fraser MO, Banner W | title = 2016 Annual Report of the American Association of Poison Control Centers' National Poison Data System (NPDS): 34th Annual Report | journal = Clinical Toxicology | volume = 55 | issue = 10 | pages = 1072–1252 | date = December 2017 | pmid = 29185815 | doi = 10.1080/15563650.2017.1388087 | s2cid = 28547821 | doi-access = free }}</ref> In the US, analysis of a national diet and supplement survey reported that about 7% of adult supplement users exceeded the UL for folate and 5% of those older than age 50 years exceeded the UL for vitamin A.<ref name=":03"/>
