Biotin, less commonly known as vitamin B7, and previously known as vitamin H or coenzyme R, is a water-soluble vitamin, part of the vitamin B complex, and a coenzyme for many reactions, including gluconeogenesis and the synthesis of fatty acids and amino acids.
Biotin deficiency is very rare.
Biotin excess does not seem to produce any ill-effects 3. However large doses of biotin in those on vitamin supplements may interfere with biochemical assays leading to misdiagnoses e.g. hyperthyroidism 4.
