Biotin functions as a cofactor for several carboxylase enzymes with key roles in metabolism. At present, the dietary requirement for biotin is unknown and intake recommendations are provided as Adequate Intakes (AIs). The biotin AI for adults and pregnant women is 30 μg/d, whereas 35 μg/d is recommended for lactating women. However, pregnant and lactating women may require more biotin to meet the demands of these reproductive states.
