Biotin is readily available from many food sources, so biotin deficiency is rare, according to Medical News Today. However, mild biotin deficiency sometimes occurs in pregnant women, so doctors often recommend 30 micrograms per day of supplemental biotin along with folic acid during pregnancy.

Biotin is a component in many foods, including oysters, baker's yeast and wheat bran, according to Medical News Today. A single large egg contains 13 to 25 micrograms of biotin, and a serving of cooked liver has 27 to 35 micrograms. Other good sources of biotin, which is also known as vitamin H and vitamin B-7, are salmon, raspberries and organ meats.
