Since there is not enough research yet to determine an RDA for biotin and there is no UL, there are no contraindications for taking biotin every day. Just be mindful of the dosage and do not exceed the recommended servings per day. However, some people experience mild side effects like nausea and digestive issues––especially at high doses––as well as breakouts in acne-prone people. For instance, seizure medications like carbamazepine (Tegretol), phenytoin (Dilantin), primidone (Mysoline), and phenobarbital (Luminal) may lower levels of this vitamin in your body (1). 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).

Biotin supplements are known for interacting with certain diagnostic tests that use biotin-streptavidin technology, and this can lead to incorrect results (14, 15, 16). This article explores available research to tell you whether biotin can help men grow hair and if there are any risks of taking the supplement. We suggest sticking to a beard care routine and grooming your beard daily with a brush to stimulate growth, in addition to a biotin regimen. Using a quality beard oil can help with dryness and promote a smoother beard.
Benefits and Side Effects of Biotin Supplements
So, I turned to board-certified dermatologist Dhaval G. Bhanusali, MD, and trichologist Bridgette Hill with Paul Labrecque Salon and Skincare Spa for the facts. Therefore, you cannot overdose on biotin, but some people may experience an upset stomach or diarrhea when taking biotin supplements. Additionally, biotin is not harmful to your kidneys if taken within the appropriate dosage amounts.
Do hair growth serums really work?
Talk with your healthcare provider about stopping it before getting your labs done. There’s no strong evidence to support using biotin for hair growth or to prevent hair loss in people without a deficiency. Even in cases where a biotin deficiency is present, biotin supplements may not necessarily prevent hair loss. However, because the hair growth supplement contained multiple ingredients — including zinc and iron, which are also necessary for hair growth — it’s not possible to attribute the study’s findings to biotin alone. In an older 2012 study, women with self-perceived thinning hair were randomized to receive either a multi-ingredient hair growth supplement that contained biotin or a placebo for 6 months (4).
However, combine a new biotin-rich diet with a vitamin B supplement. If you take your supplements with food, you can probably reduce these side effects to minimal. While supplements have some benefits, it may not be a good idea for you to take certain vitamins in large doses, so it’s best to consult with your doctor before starting a new daily routine. In addition, you should follow the dosage instructions on the label to ensure you’re safe from overdosing.

If you're looking for a biotin oil that helps promote healthy hair growth, then Difeel Premium Biotin Hair Oil might be the one for you. When looking for the best biotin oil for hair growth, it is essential to consider the quality of the oil and the concentration of biotin. The oil should be made from high-quality ingredients that are safe and effective for promoting hair growth. Additionally, the concentration of biotin in the oil should be high enough to provide maximum benefits without causing any adverse effects. Older adults, heavy drinkers, smokers, and malnourished children are also more likely to have low levels of biotin.
We have been using ELEVATE Hair Growth Oil for a while now, and we have noticed a significant improvement in the thickness and strength of our hair. The oil treatment contains bio-active nutrients that help accelerate hair growth and replenish the scalp’s natural oils essential for hair growth. It also reduces hair damage and hair loss by revitalizing the hair from the roots and repairing split ends. Maybe you’re not worried about biotin deficiency but wonder whether a biotin supplement could help you get amazing hair. Of the many there are available now, Zeichner commonly recommends Rogaine’s 5% Minoxidil Foam, supplements like Nutrafol, red light therapy, platelet-rich plasma, and in some cases, even hair transplants. Rogaine (minoxidil) and Propecia (finasteride) may be options for helping your hair grow.
biotin-rich foods for glowing skin and hair growth
If you’re experiencing hair loss, it’s best to speak with a healthcare professional to determine if there are any underlying causes. Signs of biotin deficiency include hair loss and a scaly, red rash around the mouth, eyes, and nose (3, 4). A deficiency in biotin is problematic for hair growth, so if you notice that your beard is coming in too slowly, such as over 6 months with very little hair growth, then you likely have a deficiency. Most people take biotin and experience little to no side effects, and these side effects are almost non-existent when biotin is ingested naturally through your diet. However, if you plan to supplement, you may experience some side effects if you take over 10,000 mcg in a day.
Colaco says the one exception is the very few people with an actual biotin deficiency. "Studies have shown that people who fall into this category respond well to supplementation," she says. "In most other cases, there is limited evidence to show it will help you. So many dermatologists still recommend it, as there is also no evidence that it can hurt you." According to the National Institutes of Health, the average person in a western population consumes 35–70 mcg of biotin daily from foods they eat. For most people, a supplement will not be necessary as long as they are eating a healthy, varied diet. Several other factors can also cause hair loss and thinning, including a deficiency in other nutrients like iron and zinc.
Hair loss can range from thinning to total loss of hair, can be temporary or permanent, and can affect all ages and genders. People who have gout or other conditions that require them to limit protein intake should avoid collagen supplements. Collagen supplements and products containing collagen are available.
A monthly update filled with nutrition news and tips from Harvard experts—all designed to help you eat healthier. Create healthy, balanced meals using this visual guide as a blueprint. It's important to discuss your biotin use with your healthcare provider, especially before getting your labs done. You may need to stop taking it before getting your lab work, as it can interfere with the results. Biotin use has caused the misdiagnosis of hyperthyroidism and Graves' disease, a serious autoimmune thyroid disease. In 2019, the Food and Drug Administration (FDA) warned that biotin can cause a blood test to show that a person has a low count of troponin, which is a marker necessary for the diagnosis of heart problems.

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.
More research is needed to determine the role of diet in hair loss management. Legumes, such as chickpeas, lentils, black beans, and peas, are a good alternative for people who follow a vegetarian diet and want to consume more protein. Strawberries, blueberries, raspberries, and blackberries are all loaded with antioxidants, like vitamin C, that protect cells from damage. They can also boost collagen production, promoting healthy skin, joints, and hair. Just one cup of strawberries contains 97.6 mg of vitamin C, up to 113% of the daily requirement. Nuts and seeds are rich in vitamin E, vitamin B, zinc, and healthy fats.
A diet that is deficient in specific nutrients can lead to hair loss. If you’re still willing to give biotin a try (you do you, buuut ideally not without talking to your doctor or derm first) despite the chance that it might not work, you’ve got a few options. Biotin can be used topically with a hair-growth shampoo or a thickening shampoo or, as we’ve mentioned, taken as an oral supplement, like in one of these top-rated options below. There are minimal side effects to biotin, but taking more than 5 mg could interfere with certain medical tests or interact with some medications. If considering biotin for your hair, consult your doctor to determine if it's right for you. Here is what you need to know about biotin, its relationship to healthy hair, and possible side effects.
Bhanusali explains that B5 is a part of the skin barrier, which is why this could potentially lead to skin-barrier disruption. Further research is needed to support the use of biotin supplements for this purpose in healthy individuals. Due to the multiple factors involved in hair loss and thinning, supplementing with biotin without determining the cause can prevent or delay the appropriate treatment in instances where a biotin deficiency isn’t at fault. Further, the study was small, and it’s possible that the participants were deficient in one or more nutrients present in the supplement that affect hair health.
