Biotin is a B-complex vitamin, also known as vitamin B7, that has been linked to healthy skin, hair, and nails. While biotin deficiency is rare, some people take biotin supplements to improve their hair and nail health. However, there is limited scientific research to support these claims. Biotin is found in many foods, such as sweet potatoes, seeds, broccoli, and mushrooms, and can also be taken as a supplement. While it may not make nails grow faster, it has been shown to improve nail firmness, hardness, and thickness, especially in people with brittle nails.

What You'll Learn
Biotin deficiency is rare
Biotin is part of the vitamin B family and is also known as vitamin B7, coenzyme R, and vitamin H. It is an essential nutrient that supports the body's metabolism and helps maintain healthy nervous system and gene function. It is also believed to promote healthy skin, hair, and nails.
Despite the rarity of biotin deficiency, it is marketed as a supplement to promote nail growth and strength. Some people claim that taking biotin supplements helps boost their nail growth and strength. However, there is limited scientific research to support these claims. While some small studies have shown positive results in treating brittle nails with biotin supplementation, more high-quality research is needed to prove its effectiveness.
It is important to note that consuming biotin-rich foods or supplements may help strengthen brittle nails and improve their growth. Biotin is made up of protein and amino acids, which support keratin production, essential for nail health. While biotin may not be a cure-all for nails, as results vary and it may take 4 to 12 months to see improvements, it can be beneficial for some individuals.
Additionally, other vitamins and minerals are crucial for nail health, including zinc, vitamin B12, and folate (vitamin B9). A well-rounded, nutrient-rich diet is likely the best way to achieve strong and healthy nails.

Biotin-rich foods and supplements
Biotin is part of the vitamin B family, also known as vitamin B7, coenzyme R and vitamin H. It is an essential nutrient that supports your metabolism and helps maintain a healthy nervous system and gene function. Biotin is made up of protein and amino acids, which support keratin production in the body. Keratin is a type of protein that forms the cells that make up the tissue in nails.
Biotin-rich foods include sweet potatoes, seeds, broccoli, and mushrooms. Biotin is also found in many common supplements, including adult daily multivitamins and prenatal vitamins, which typically contain 100% of the recommended daily value for biotin. Other supplements, like “super B” vitamin formulations or vitamins that promote hair and nail growth, can contain up to 10,000% of the daily value.
While biotin deficiency is rare, consuming biotin through foods or supplements may help strengthen brittle nails and improve their growth. Studies show that taking 2.5 mg of biotin daily may improve nail firmness, hardness, and thickness. One study found that over half of the people taking 2.5 mg of biotin per day experienced a 25% increase in nail thickness. However, it's important to note that the studies on biotin and nail health have been small and more research is needed to prove its effectiveness.
It's always better to get your vitamins and minerals through a balanced diet rather than supplements. A nutrient-rich diet is likely the best way to achieve strong, healthy nails. If you are considering taking biotin supplements, it is recommended that you discuss your health goals with a licensed healthcare professional first.
