Many people take biotin supplements with the hope of achieving longer, stronger nails. While there is little research to support the claim that biotin increases nail growth, studies have shown that it can strengthen brittle nails, making them less prone to splitting or breaking. Biotin is a B-complex vitamin that supports keratin production, which is essential for nail strength and resilience. While it may take up to a year to see noticeable results, biotin supplementation may be worth considering for those looking to improve their nail health. However, it is always recommended to consult with a healthcare professional before adding any supplements to your routine.

What You'll Learn
Biotin deficiency can cause brittle nails
Biotin is an essential nutrient found in foods and supplements. It is also known as vitamin B7 or vitamin H. While biotin is widely marketed as a remedy for brittle nails, there is limited evidence to support this claim. However, biotin deficiency can lead to nail problems, and increasing biotin intake through diet or supplementation can help improve nail health in individuals with a biotin deficiency.
Biotin deficiency is rare in healthy individuals since most people get enough biotin in their diet. Genetic conditions, certain medications, and some pathologies can cause biotin deficiency. Brittle nail syndrome, for example, is a condition that has been treated with biotin supplementation. Studies have shown that taking 2.5 mg of biotin daily may improve nail firmness, hardness, and thickness.
It is important to note that while biotin may strengthen nails, there is no evidence that it increases nail growth rate. Additionally, simply increasing protein intake is unlikely to strengthen nails unless there is a protein deficiency, which is uncommon in developed countries. Instead, keeping nails moisturized can help prevent them from drying out, cracking, and splitting, allowing them to grow longer.
If you suspect you have a biotin deficiency due to brittle nails, it is recommended to consult a healthcare professional. They can evaluate your diet and biotin levels and help determine the cause of your nail symptoms. While biotin supplements are generally safe, it is important not to take large doses without medical supervision.
In summary, while biotin deficiency can cause brittle nails, simply taking biotin supplements may not be enough to improve nail health in individuals without a biotin deficiency. More research is needed to fully understand the role of biotin in nail health and its potential benefits for those without underlying deficiencies.

Biotin supplements may strengthen nails
While there is insufficient scientific evidence to support the claim that biotin supplements make nails grow faster, they may help strengthen weak or brittle nails. Biotin is a B-complex vitamin, also known as vitamin B7, coenzyme R, or vitamin H, that promotes healthy cell growth. It is composed of protein and amino acids, which aid in the production of keratin, a protein that forms the cells that make up nail tissue.
According to Elizabeth Geddes-Bruce, a board-certified dermatologist at Westlake Dermatology, "one sign of biotin deficiency is brittle nails, so biotin supplementation is one option you can try to strengthen brittle nails." However, she adds that "this comes with varying results." Marcela Correa, owner of NYC's Medi Pedi NYC and a medical pedicurist, agrees that biotin supports keratin production in the body. Celebrity manicurist Elle, whose clients include Jennifer Lopez, Blake Lively, and Kelly Ripa, also attests to the benefits of biotin for nail health.
Studies have shown that taking 2.5 mg (2,500 mcg) of biotin daily may improve nail firmness, hardness, and thickness. In one study, over half of the participants taking this dosage experienced a 25% increase in nail thickness. However, it's important to note that the studies on biotin and nail health have been relatively small and of varying quality, so more research is needed to conclusively prove its effectiveness.
Biotin supplements may be a helpful addition to your routine if you struggle with brittle nails. However, it's always recommended to consult with your healthcare provider before starting any new supplement to ensure it's safe and appropriate for your individual needs. Additionally, maintaining a balanced diet that includes biotin-rich foods such as egg yolks, nuts, milk, grains, salmon, and sweet potatoes can also contribute to nail health.

Biotin-rich foods include egg yolks, nuts, milk, grains, salmon and cauliflower
Biotin is a B vitamin that helps convert food into energy. It also supports eye, hair, skin, brain, and liver function. While biotin deficiency is rare, it may occur in people with certain genetic conditions. Low biotin levels can lead to hair loss and brittle nails.
Biotin-rich foods include egg yolks, nuts, milk, grains, salmon, and cauliflower. Other good sources of biotin are legumes, organ meats, seeds, mushrooms, avocados, sweet potatoes, and yeast. For example, a medium avocado contains 1.85 mcg of biotin, or 6% of the daily value (DV). Similarly, a 3/4-cup serving of whole soybeans provides 19.3 mcg of biotin, or 64% DV.
While biotin supplements are available, most people can meet their biotin needs by consuming a balanced diet that includes these biotin-rich foods. Additionally, cooking methods can impact biotin absorption. For example, fully cooking eggs can improve biotin absorption and reduce the risk of foodborne illness.
Although biotin is marketed for nail growth, there is limited scientific research to support these claims. However, studies suggest that biotin can strengthen nails, making them less prone to breakage, which may indirectly lead to growing longer nails over time. For instance, one study found that taking 2.5 mg of biotin daily resulted in a 25% increase in nail thickness for over half of the participants.
Overall, while biotin may not directly accelerate nail growth, it can help improve nail health and reduce breakage, potentially enabling nails to grow longer over time.

Biotin is found in many health and beauty products, and it is also available as a standalone dietary supplement. Biotin-rich foods include egg yolks, nuts, milk, grains, salmon, sweet potatoes, broccoli, and cauliflower. Since biotin is a water-soluble vitamin, any excess is naturally filtered out by the body.

There is little evidence that biotin supplements aid nail growth
While biotin supplements are often marketed as a way to improve nail growth, there is little scientific evidence to support these claims. Biotin is a B-complex vitamin, also known as vitamin B7, that promotes healthy cell growth and aids in the metabolism of protein-building amino acids essential for nail growth. It is naturally found in egg yolks, nuts, milk, grains, salmon, and cauliflower, and can also be taken as a dietary supplement.
Some sources suggest that biotin supplements may help strengthen weak or brittle nails, making them less likely to split or break, which may indirectly lead to longer nails over time. However, the existing studies on biotin and nail growth have been relatively small and of varying quality. More research is needed to conclusively prove that biotin supplementation significantly impacts nail growth.
One study found that taking 2.5 mg of biotin daily may improve nail firmness, hardness, and thickness. Over half of the participants taking this dosage experienced a 25% increase in nail thickness. However, it's important to note that this study focused on nail strength and thickness rather than nail growth rate.
Additionally, it's worth mentioning that biotin deficiency is rare. Unless you have a confirmed biotin deficiency, simply consuming a balanced diet that includes biotin-rich foods may be sufficient to meet your body's needs without the need for supplementation. As always, it is advisable to consult with a healthcare professional before adding any supplements to your diet to ensure they are appropriate for your specific needs and health goals.
