By promoting cell growth and improving the structure of the hair, biotin contributes to overall hair health and vitality. Biotin supports the production of keratin, a protein that forms the structure of hair strands. In this article, we will explore the science behind biotin and hair growth and answer all of your burning questions. Biotin, also known as vitamin B7, has gained popularity in recent years as a potential solution for those struggling with hair loss or looking to improve the overall health of their hair.
Health Alerts from Harvard Medical School
In a case report on the subject of biotin supporting hair health published in the Pediatric Dermatology journal in 2007, it was only found to help a child with a very rare condition called Uncombable Hair Syndrome. However, like biotin, many of these are not scientifically proven to have a positive effect. Despite these claims, though, there’s limited evidence to suggest that supplementing with biotin or lathering it through your hair promotes hair growth in non-deficient people. To help promote baby health, take a prenatal vitamin that contains biotin and folic acid during pregnancy. High doses of biotin, however, can be dangerous to the baby, so additional supplementation of biotin isn’t recommended.
Practical pointers about protein
Medical guidance has also suggested that genetic conditions affecting intestinal bacteria balances may result in biotin production deficiencies. This may be the case for tests looking at troponin levels and thyroid function. According to an analysis, most biotin-related false results occur in thyroid disease-related tests. It’s also worth noting that some antiepileptic drugs — like carbamazepine, primidone, phenytoin, and phenobarbital — can lower biotin levels. In addition to food, the bacteria in your intestines can make biotin.
Biotin Side Effects
Remember, biotin supplements should not replace a balanced diet, and it is always best to obtain nutrients from natural food sources whenever possible. While there is no UL (Tolerable Upper Intake Level) for biotin, consuming more than the recommended daily amount can lead to some negative side effects. This can be as mild as some nausea and digestive issues, but at higher doses can lead to breakouts in acne-prone people. Let your doctor know if you’re supplementing with biotin before taking any laboratory tests since higher levels can cause false results.

According to the National Institutes of Health, humans have a very minor need for biotin – 30 mcg for adults and 25 mcg for teens, but when people take the supplement for hair growth, the dose is much higher. But because people with a deficiency often show symptoms of hair loss or a scaly red rash, some doctors and supplement companies recommend increasing your intake. The word “biotin” comes from the ancient Greek word “biotos,” which means “life” or “sustenance.” B vitamins, and specifically biotin, help keep your skin, hair, eyes, liver, and nervous system healthy.
Vitamins & Supplements
Found in a plethora of foods and available as a supplement, biotin is most well-known for strengthening hair and nails and combatting alopecia. If you're nurturing your hair and are still experiencing hair loss, there are in-office treatments to consider — specifically laser and platelet-rich plasma (PRP), which is recommended by Gross and Bhanusali. Samolitis suggests blood tests to indicate if you have a hormonal imbalance that may require something like a DHT (dihydrotestosterone, a metabolite form of testosterone) blocker that can be applied topically.
While certain thyroid disorders and diseases can negatively impact the health of our hair and nails, sometimes it’s just plain old aging, poor diet, or even stress. If you want to make sure you’re getting enough biotin, the daily recommended biotin intake is 30 micrograms (mcg) for adults, according to the National Institute of Health. Meanwhile, “the goal of a serum is to target the hair follicle directly by delivering compounds that may allow for improved or optimal hair growth,” says Dr. Mirmirani. These ingredients are those that aren’t typically found in the diet, such as minoxidil and plant-based compounds. But these do take longer to work, as supplements “must first be metabolized by the body and dispersed by the bloodstream to be beneficial,” says Dr. Shaver. And oral supplements may have more systemic side effects and interactions with other medications, so it’s especially important to check with your doctor before taking a supplement.

Food should be the first choice when looking for sources of biotin. Biotin supplements are available alone, combined in a supplement with other B vitamins, or included in a multivitamin. This article looks at why people need biotin, the recommended intake, sources, and any possible health risks.
Bacteria in the large intestine naturally produces enough biotin to reach the body's daily requirements and intake can easily be achieved through diet with biotin being found in foods such as eggs, fish and nuts. Whilst biotin deficiency is rare, it has been linked to hair loss and thinning, with these cases seeing the most beneficial results from biotin supplementation, particularly in women (Trueb, 2016). Biotin can potentially make strands stronger and shinier, which is why those with dull, damaged locks could most benefit from using it for their hair.
Studies found no adverse effects in 10 to 50 mg/day to as much as 200 mg/day. But, it's important to keep dosage below 5 mg a day, says Elizabeth Damstetter, MD, a dermatologist and assistant professor at Rush Medical Center. That's because biotin absorbed in your bloodstream may interfere with test results for hours or days after the fact, such as thyroid hormone tests or a troponin test, which helps diagnose heart attacks. "What we usually do in clinical practice is recommend biotin for people with dry, breaking hair, or brittle nails," says Olga Bunimovich, MD, a dermatologist at the University of Pittsburgh Medical Center. However, those who do not have biotinidase deficiency should first try to get enough biotin from their diet, as dietary biotin also enhances the intake of other beneficial nutrients that work alongside it.
