Does biotin only potentially help with hair growth?

Biotin, also known as vitamin B7, supports many of your body’s systems, including your nervous system, liver, eyes, hair, and skin. It helps the enzymes in your body carry out their jobs and keeps cells working as they should. Problems in older adults have not been reported with intake of normal daily recommended amounts. Drug Interactions In most cases, taking biotin won't hurt you. Experts say it's difficult to take so much biotin that you hurt yourself or overdose (Bistas, 2020). However, taking too much of it can have secondary health consequences, which we’ll discuss below. DuVigneaud V, Hofmann K, Melville DB, György P (August 1941). "Isolation of Biotin (vitamin H) from Liver". Journal of Biological Chemistry. 140 (2): 643–51. doi: 10.1016/S0021-9258(18)51355-7. AlbarracinCA, et al. (2008). Chromium picolinate and biotin combination improves glucosemetabolism in treated, uncontrolled overweight to obese patients with type 2diabetes. [Abstract].

The European Food Safety Authority (EFSA) also identifies AIs, setting values at 40μg/day for adults, pregnancy at 40μg/day, and breastfeeding at 45μg/day. For children ages 1–17 years, the AIs increase with age from 20 to 35μg/day. [10] Safety [ edit ] Sweet potatoes have 2.4 micrograms of biotin in half a cup, about 8% of your daily value of biotin. Biotin is likely effective in alternative medicine as an aid in treating or preventing low levels of biotin. Low levels of biotin can be caused by malnutrition, rapid weight loss, long-term tube feeding, and other medical conditions.

Can I put liquid biotin in my hair?

Most people get enough biotin from the foods they eat. However, certain groups of people are more likely than others to have trouble getting enough biotin: a b Said HM (November 2013).
