Vitamin toxicity is primarily with regard to fat-soluble vitamins

With few exceptions, like some vitamins from B-complex, hypervitaminosis usually occurs more with fat-soluble vitamins (D, E, K and A or 'DEKA'), which are stored in the liver and fatty tissues of the body. These vitamins build up and remain for a longer time in the body than water-soluble vitamins.

Conditions include:

Hypervitaminosis A
Hypervitaminosis D
Hypervitaminosis E
Hypervitaminosis K

High-dosage A; high-dosage, slow-release vitamin B3; and very high-dosage vitamin B6 alone (i.e. without vitamin B complex) hypervitaminoses are sometimes associated with side effects that usually rapidly cease with supplement reduction or cessation.

High doses of mineral supplements can also lead to side effects and toxicity. Mineral-supplement poisoning does occur occasionally, most often due to excessive intake of iron-containing supplements.
