Strong and healthy nails are a sign of good overall health. A deficiency in certain vitamins, minerals, and nutrients can negatively affect nail health. B vitamins are essential for energy production, metabolism, and cell growth. Biotin, also known as vitamin B7, is crucial to nail health as it helps form keratin, the main protein that makes up nails. It helps to keep nails strong, prevents brittleness, and enhances nail strength. Vitamin B12 is also essential for nail health as it enables iron to be absorbed by the body, ensuring the formation of enough red blood cells. A deficiency in vitamin B12 can cause nail discolouration and deformation. A well-balanced diet that includes vitamins, minerals, nutrients, and healthy fats is the best way to achieve strong and healthy nails.

Biotin (vitamin B7)
Biotin, also known as vitamin B7, is a water-soluble nutrient that is crucial for nail health. It helps form keratin, the protein that makes up nails, and promotes healthy cell growth. Biotin also aids in the metabolism of protein-building amino acids, which are essential for nail growth and strength. A biotin deficiency can lead to brittle nails, which may be more susceptible to breakage.
Biotin-rich foods include eggs, nuts, salmon, avocados, dark leafy greens, sweet potatoes, beef liver, dairy products, yeast, and cauliflower. It is recommended that adults consume 30 mcg of biotin per day, although deficiency is rare.
Supplementation with biotin tablets is also an option for those at risk of low biotin levels. According to the NHS, taking 0.9 mg or less of biotin per day is unlikely to cause any harm. However, it is important to note that consuming too much of one vitamin can lead to waste and may even deplete another. Therefore, it is generally recommended to obtain nutrients from a balanced diet, ensuring your nails get all the nutrients they need to grow strong and healthy.
In addition to biotin, other vitamins that promote nail health include vitamins A, C, and E. Vitamin C, for example, helps the body produce collagen, a protein that gives structure to nails, skin, and hair. A well-rounded approach to nutrition will ensure your body functions at its best, resulting in strong and healthy nails.

Vitamin B12
Vitamin B7, or biotin, is another B vitamin that is crucial for nail health. Biotin helps form keratin, the main protein that constitutes nails, and it also aids in the metabolism of protein-building amino acids that are essential for nail growth. Biotin-rich foods include eggs, nuts, salmon, avocados, sweet potatoes and dark leafy greens.
It is important to note that while supplements can be beneficial, a balanced diet is the best way to achieve strong and healthy nails. A varied diet that includes a range of vitamins, minerals, healthy fats, carbohydrates, proteins and water will ensure your nails receive all the nutrients they need to thrive.

Vitamin B9 (folic acid)
Vitamin B9, also known as folic acid or folate, is important for nail growth and health. It contributes to red blood cell formation and the development of new cells. A deficiency in vitamin B9 can cause a pigment change in your nails and make them rigid and brittle.
To prevent a deficiency, adults require 400 mcg of folate per day, though pregnant women have an increased need for this vitamin. Vitamin B9 can be found in dark green vegetables, citrus fruits, beans, peas, lentils, nuts, seeds and avocados.
Biotin (vitamin B7) is another B-complex vitamin that promotes healthy cell growth and aids in the metabolism of protein-building amino acids that are essential for nail growth. Biotin-rich foods and supplements may help strengthen your brittle fingernails. Vitamin B7 can be found in eggs, nuts, salmon, avocados, and dark leafy greens.
Vitamin B12 also plays a role in nail health by enabling the absorption of iron, which is necessary for keeping nails strong and healthy. A deficiency in vitamin B12 can result in blue nails, bluish-black pigments with wavy longitudinal dark streaks and brownish pigmentation. Vitamin B12 can be found in meat, poultry, fish, eggs and dairy.
In addition to B vitamins, vitamins A, C, and E also promote healthy nails. Vitamin C is essential for the production of collagen, a protein that gives shape, strength and integrity to many tissues, including fingernails. Vitamin A is necessary for cell growth and differentiation, while vitamin E is another nutrient that is important for healthy nails.

Vitamin B5
While there is no consensus on the impact of vitamin B on nail growth, some sources suggest that vitamin B5 can help relieve menopause-related nail thinning issues. Vitamin B5 is also found in some nail-strengthening treatments, which may help nails grow longer by reducing breakage.
Vitamin B7 (biotin) is the most widely researched B vitamin in relation to nail health. Several studies have shown that biotin can strengthen brittle nails, making them less likely to break and allowing them to grow longer. Biotin is found in many foods, including organ meats, egg yolk, dairy products, yeast, salmon, avocado, sweet potato, nuts, seeds, and cauliflower.
Vitamin B9 (folate) is also important for nail health, as it contributes to red blood cell formation and the development of new cells. A deficiency in vitamin B9 can cause pigment changes and make nails rigid and brittle. Vitamin B9 can be found in dark green vegetables, citrus fruits, beans, peas, lentils, nuts, seeds, and avocado.
Vitamin B12 is necessary for keeping nails strong and healthy, and a deficiency can cause blue or bluish-black discolouration of the nails. B12 is primarily found in animal foods such as meat, poultry, fish, eggs, and dairy.
