Wikipedia
Hypervitaminosis refers to a condition of abnormally high storage levels of vitamins, which can lead to toxic symptoms. The medical names of the different conditions are derived from the vitamin involved: an excess of vitamin A, for example, is called hypervitaminosis A.
Hypervitaminosis primarily affects the fat soluble vitamins, as these are stored by the body for longer period than the water-soluble vitamins. However, avoiding excesses of both classes of vitamins can make the condition hard to get.
Generally, toxic levels of vitamins stem from high supplement intake and not from dietary sources. Toxicities of fat-soluble vitamins can also be caused by a large intake of highly fortified foods, but foods rarely deliver dangerous levels of fat-soluble vitamins.
The Dietary Reference Intake recommendations from the United States Department of Agriculture define a "tolerable upper intake level" for most vitamins.
High dosage vitamin A; high dosage, slow release vitamin B; and very high dosage vitamin B alone (i.e. without vitamin B complex) are sometimes associated with vitamin side effects that usually rapidly cease with supplement reduction or cessation.
