However, the supplement also contains other ingredients that may help with hair health, including silica and saw palmetto extract (4, 11). Regardless, be sure to clear a high dose biotin supplement like this one with a healthcare professional, especially if you plan to take it over a long period.

The body can absorb 100% of biotin taken by mouth, even at high doses, unless absorption issues are present, like inflammatory bowel disease (IBD). If you are eating a balanced diet of fruits and vegetables, varied protein sources, and complex carbohydrates, you likely are getting enough biotin. If you are experiencing noticeable hair loss, make an appointment to see a doctor to determine if there are any underlying problems. It could be a biotin deficiency, but it could also be something more serious.
Biotin Benefits: What the Experts Have to Say
Biotin supplements may also interfere with anticonvulsant medications, so make sure to speak with a healthcare professional before taking biotin if you’re on an anticonvulsant (1). Be sure to let a healthcare professional know if you’re taking a biotin supplement prior to having lab work done. However, there’s limited evidence to support this particular use for biotin because most people aren’t deficient in biotin — despite its popularity as a hair, skin, and nails vitamin (12). Supplementation with vitamin D may not have direct links with hair growth, but having a deficiency may impact hair health.
"Biotin also has the potential to stimulate the production of keratin, the main protein in the hair and nails," Vaca-Flores adds. "Since keratin is the main building block of the hair, it can be inferred that promoting its production can benefit hair health." It also includes vitamin D, iron, and zinc, all of which have been linked to hair loss in people with these nutrient deficiencies.
False laboratory tests
Dr. Green recommends seeing a board-certified dermatologist to go over your options. “These are formulated with all-natural and clinically-proven ingredients that can make a difference in your hair with consistent usage,” she says. Taking vitamin D with a meal that contains fat will improve the absorption of this vitamin. All products featured on Glamour are independently selected by our editors.

Zinc
The majority of participants either were known to have a biotin deficiency or had a history of poor hair and nail growth that indicated other underlying issues. 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. 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. Anyone who is considering taking biotin supplements should first check with a doctor. Raw eggs contain a glycoprotein called avidin that inhibits the absorption of biotin. Eating two or more raw egg whites a day for several months has been linked to biotin deficiency.
Check for contaminants and any other potentially unwanted ingredients. Biotin may also lower troponin (a protein found in heart muscles) levels. Troponin found in the blood is used as a marker of a heart attack or heart damage. Falsely lower levels could lead to a missed heart attack diagnosis.

Other causes include male and female pattern baldness, alopecia areata, stress, and certain medical treatments. Although a 2019 review found that these products can be beneficial for treating hair loss, there is little evidence to suggest that the hair will continue growing after a person stops using the product. However, it is worth noting that over-supplementation with the fat-soluble vitamin E can cause hair loss as well as other adverse side effects. Some people choose to rub vitamin E oil directly onto their skin or scalp, believing that it will speed up cell regeneration. Nevertheless, getting enough vitamin B12 is essential for overall health.
Some sources have suggested that vitamin B12 may play a role in hair health. However, several studies mentioned in a 2019 review found no evidence of a link between changes in B12 levels and hair loss or retention. Eating a well-balanced diet that contains essential vitamins can help maintain hair health. While more research is necessary, certain vitamins, such as D and E, may provide more benefits than others.
This is usually not a problem, but there can be some unintended side effects from taking too much biotin. The Food and Nutrition Board has not found sufficient data to set an RDA for biotin, which is why you’ll only see AIs for this nutrient. This post contains links through which we may earn a small commission should you make a purchase from a brand.
From coloring and heat damage to aging and health problems, there’s a whole host of reasons you may want to boost your hair growth. Biotin has been shown to be safe for most people when taking up to 300 milligrams (300,000 micrograms) daily for up to six months. But experts typically recommend taking lower doses, like 2.5 milligrams per day. However, additional supplementation may be necessary during pregnancy or if a person has a biotin deficiency. It’s important to understand what’s causing your hair loss, but this can take some detective work. Dr. Bergfeld says dermatologists start with a thorough physical exam.
Even researchers have not come to a conclusion whether high accumulation of biotin over an extended time period is likely to pose any health threats. However, an overdose of biotin may cause insomnia, excessive thirst, and urination (13). Antiepileptics are commonly used to treat seizure disorders, nerve pain, and bipolar disorder. Retinoids are a class of compounds derived from vitamin A, commonly used to treat acne, psoriasis, and other dermatological conditions (11).
In addition to food, the bacteria in your intestines can make biotin. However, the role of gut bacteria on the overall biotin status of humans remains unknown — in part due to the complexity of the gut microbiota and the factors that influence its composition (8). Thus, it’s best — both for your safety and nutrition — to avoid raw eggs (2). Excess intake of this vitamin has also been linked to the measurement of false troponin levels — used to indicate heart attacks — leading to delayed treatment and even death (14, 15, 16).
Sun exposure is also essential, as this enables the body to produce vitamin D. People should remember to wear sunscreen, however, as too much sun exposure over time can lead to skin damage. The Office of Dietary Supplements recommend that adults get 600 international units (IU), or 15 micrograms (mcg), of vitamin D per day.
