Includes a variety of vegetables; fruits; grains (at least half whole grains); fat-free and low-fat milk, yogurt, and cheese; and oils. FDA advises health care 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]. Interactions with Medications

The amount of biotin you need each day depends on your age. Average daily recommended amounts are listed below in micrograms (mcg). Life Stage Allergies and dietary needs. Also consider any allergies or dietary considerations you may have. Klaire Labs and Pure Encapsulations offer hypoallergenic biotin supplements, while Garden of Life offers organic, vegan-friendly options. A limited number of reliable indicators of biotin status is available [ 7]. In healthy adults, the concentration of biotin is 133–329 pmol/L in serum and 18–127 nmol/24 hours in urine [ 2]. Abnormally low urinary excretion of biotin is an indicator of biotin deficiency, as is abnormally high excretion of 3-hydroxyisovaleric acid (higher than 3.3 mmol/mol creatinine) or 3-hydroxyisovalerylcarnitine (higher than 0.06 mmol/mol creatinine) resulting from reduced activity of MCC [ 2, 7, 8]. The most reliable individual markers of biotin status, including deficiency and sufficiency, are biotinylated MCC and propionyl-CoA carboxylase in white blood cells [ 7]. Oral administration of large doses of biotin increases serum concentrations of biotin and its metabolites [ 1, 9]. However, serum concentrations of biotin and its catabolites are not good indicators of marginal biotin deficiency because they do not decrease sufficiently in people with marginal biotin deficiency for these changes to be detectable with existing tests [ 3, 10].

Does biotin only potentially help with hair growth?

Most people can take biotin supplements without experiencing any side effects. However, it is possible for people to take them and experience 13: You can find it in animal-based foods, seeds, nuts, nutritional yeast and some vegetables like sweet potatoes

The vitamins: fundamental aspects in nutrition and health. Third ed. Burlington, MA: Elsevier Academic Press; 2008:331-44. Biotin supplements are often glamorized as a treatment for hair loss and to promote healthy hair, skin, and nails. Although a deficiency of biotin can certainly lead to hair loss and skin or nail problems, evidence showing a benefit of supplementation is inconclusive. A handful of case reports and small trials have shown a benefit, but the study designs had weaknesses: Fujimoto W, Inaoki M, Fukui T, Inoue Y, Kuhara T. Biotin deficiency in an infant fed with amino acid formula. J Dermatol 2005;32:256-61. [ PubMed abstract] As a result, it’s important to talk with a healthcare professional before taking a biotin supplement. The following groups are among those most likely to have inadequate biotin status. Individuals with biotinidase deficiency
