Table 1 lists the current AIs for biotin [ 1 ]. Food Many foods contain some biotin. Foods that contain the most biotin include organ meats, eggs, fish, meat, seeds, nuts, and certain vegetables such as sweet potatoes [ 2 , 12 ]. The biotin content of food can vary; for example, plant variety and season can affect the biotin content of cereal grains, and certain processing techniques e.
Cooking denatures avidin, making it unable to interfere with biotin absorption [ 13 ]. The U. Food and Drug Administration FDA developed DVs to help consumers compare the nutrient contents of foods and dietary supplements within the context of a total diet.
The DV for biotin is 30 mcg for adults and children age 4 years and older [ 15 ]. FDA does not require food labels to list biotin content unless biotin has been added to the food. Biotin deficiency is rare [ 12 , 18 ], and severe biotin deficiency in healthy individuals eating a normal mixed diet has never been reported [ 13 ]. The signs and symptoms of biotin deficiency typically appear gradually and can include thinning hair with progression to loss of all hair on the body; scaly, red rash around body openings eyes, nose, mouth, and perineum ; conjunctivitis; ketolactic acidosis which occurs when lactate production exceeds lactate clearance and aciduria abnormal amounts of acid in urine ; seizures; skin infection; brittle nails; neurological findings e.
Individuals with biotinidase deficiency Biotinidase deficiency is a rare autosomal recessive disorder that prevents the body from releasing free biotin, leading to biotin deficiency despite normal intake. Without treatment, biotinidase deficiency produces neurological and cutaneous symptoms, and profound biotinidase deficiency can lead to coma or death [ 19 , 20 ].
Individuals with chronic alcohol exposure Chronic exposure to alcohol inhibits the absorption of biotin [ 21 ]. Pregnant and breastfeeding women At least a third of pregnant women develop marginal biotin deficiency in spite of normal biotin intakes; plasma and breastmilk concentrations of biotin decrease in lactating women, even when their dietary biotin intakes exceed the AI [ 2 , 18 , 22 ].
Additional research is needed to understand the clinical significance of these findings. Signs of biotin deficiency include skin rashes, hair loss, and brittle nails [ 10 , 13 ]. Therefore, biotin supplements are often promoted for hair, skin, and nail health [ 16 , 23 , 24 ]. However, these claims are supported, at best, by only a few case reports and small studies. The evidence on biotin supplementation to treat brittle nails includes three small studies that did not include a placebo group, and these reports do not indicate the baseline biotin status of study participants.
One of these studies assessed the effects of 2. In the second study, 2. Finally, the third, retrospective study in 35 patients with brittle nails found that 2. Only case reports are available to support claims that biotin supplements can promote hair health, and these reports were only in children [ 28 , 29 ]. Future studies are needed to determine whether biotin supplements might improve hair, nail, and skin health, especially among healthy individuals.
The FNB was unable to establish ULs for biotin because there is no evidence in humans that biotin is toxic at high intakes [ 1 ]. High biotin intakes, and potentially even intakes greater than the AI, may pose another type of health risk [ 32 ]. Supplementing with biotin beyond recommended intakes can cause clinically significant falsely high or falsely low laboratory test results, depending on the test. These incorrect results may lead to inappropriate patient management or misdiagnosis of a medical condition.
The following section has more details on these interactions. Very high intakes of biotin may interfere with diagnostic assays that use biotin-streptavidin technology and are commonly used to measure levels of hormones such as thyroid hormone and other analytes such as hydroxyvitamin D, producing falsely normal or abnormal results [ 9 , 32 ].
Even a single 10 mg dose of biotin has interfered with thyroid function tests administered within 24 hours of taking the supplement [ 38 ]. According to the Food and Drug Administration FDA , a patient with a high intake of supplemental biotin died following a troponin test to help diagnose a heart attack that gave a falsely low result because the test was subject to biotin interference [ 32 ]. FDA advises healthcare providers to ask their patients about any supplements they may be taking that contain biotin and to consider biotin interference as a possible source of error if laboratory test results do not match the clinical presentation of the patient [ 32 ].
Biotin can interact with certain medications, and some medications can have an adverse effect on biotin levels. One example is provided below.
