FAQ:

Q: How much biotin should I take?

A: Biotin Intake Recommendations. 30 mcg (micrograms) for adults over 18 years of age. 25 mcg for young adults ages 14 to 18. 20 mcg for children ages 9 to 13. 12 mcg for children ages 4 to 8. 8 mcg for children ages 1 to 3. 7 mcg for children under 12 months old. 35 mcg for pregnant women.

Q: Can a person take too much biotin?

A: While there are no side effects from having too much biotin in your system, the excess could cause another major issue that shouldn’t be ignored. The Food and Drug Administration (FDA) reports that the high levels of biotin in supplements can cause clinically significant errors in lab test results. Many lab tests utilize biotin because it bonds with proteins that, when measured, can reveal certain health problems.

Q: What is biotin prescribed for?

A: Small amounts of biotin are found in foods like eggs, milk, and bananas. Biotin is used as a medical therapy in prescription form to treat a documented biotin deficiency with related symptoms of hair and skin changes. It’s also sometimes used in children with a specific condition called biotinidase deficiency.

Q: Is 5000 MCG of biotin daily too much?

A: While the benefits of biotin are well-known, few people are aware of its side effects, such as mild nausea and increased thirst. However, doses of up to up to 10 milligrams a day are safe, according to Mayo Clinic. As long as you do not take more than two servings of biotin 5,000 mcg per day, you are unlikely to experience adverse reactions.
