Biotin is obtained from food, and is also produced by predominant organisms (especially bifidobacteria) in the healthy human gut. Biotin deficiency was once thought to be rare because such small amounts are required and clinical signs of deficiency are non-spe­cific.187 It was thought that only certain disorders of in­fancy, such as Leiners disease (desquamative erythroder­ma) and other forms of seborrheic dermatitis, arc clinical manifestations of biotin deficiency. Recent findings are shifting the clinical outlook for biotin deficiency.

維生素H（生物素）可由食物中獲取，以可由健康人體內臟主要器官產生（尤其是比菲德氏菌）。因為生理需求量小加上臨床徵兆不明，『生物素不足』一度被視為 極罕見。以前認為只有一些特定嬰兒小疾病（如嬰兒托屑紅皮症）或脂漏性皮膚炎等才是生物素不足的臨床表現。最近的發現才改變了醫學對生物素不足的觀點。
