There are several vitamins that can help with fingernail growth and strength. Vitamin C is essential for the production of collagen, which gives shape and strength to nails. Vitamin B, particularly biotin, helps form keratin, the protein that makes up nails, and prevents them from becoming brittle. Vitamin E is an ultra-hydrating oil that helps heal and promote new nail growth. Other important vitamins for nail health include vitamin A, vitamin D, and folate, a B vitamin that helps create healthy red blood cells. In addition, minerals such as zinc, calcium, and iron play a vital role in nail growth and strength.

Vitamin C helps produce collagen, which gives nails strength and structure
Vitamin C is an essential nutrient that cannot be produced by the body. It is required for the production of collagen, a protein that gives shape, strength, structure, and integrity to many tissues. Collagen is the most abundant protein in the body and acts like a glue that holds everything together. It is found in the skin, bones, tendons, ligaments, and even in blood vessels.
Vitamin C helps in the formation of collagen and encourages the body to produce more of it. It does so by promoting the activity of fibroblasts, the cells responsible for making collagen and other fibers in connective tissue. Collagen provides a structural framework for bones, making them resilient and reducing the risk of fractures. It also helps in the absorption of calcium, a mineral vital for bone health.
Similarly, collagen lends nails their strength, shape, and resistance to breakage. Vitamin C supports nail health by promoting collagen synthesis and aiding in tissue repair. A deficiency in vitamin C can weaken collagen production, potentially leading to fragile bones, joint pain, and gum issues.
To ensure adequate vitamin C intake for nail health, include citrus fruits like oranges, grapefruits, and lemons in your diet. Other good sources of vitamin C include strawberries, kiwi, guava, bell peppers, broccoli, Brussels sprouts, and kale. These foods provide vitamin C and other essential nutrients. If you struggle to get enough vitamin C from your diet, consider taking a supplement, but always consult a healthcare professional first.

Vitamin B, especially B7 and B9, helps supply fatty acids to nails, keeping them hydrated
Vitamin B is essential for nail health, and deficiencies in specific types of this vitamin can negatively affect your nails. Vitamin B7, also known as biotin, is a B-complex vitamin that promotes healthy cell growth and aids in the metabolism of protein-building amino acids, which are essential for nail growth. A biotin supplement or biotin-rich foods may help strengthen brittle nails and improve their growth. A study in 35 people with brittle fingernails found that 2.5 mg of biotin per day for six weeks to seven months improved symptoms in 63% of participants. Biotin is most concentrated in organ meats such as liver, but it can also be found in egg yolk, dairy products, yeast, salmon, avocado, sweet potato, nuts, seeds, and even cauliflower.
Folate, or vitamin B9, is another important B-vitamin for nail growth and health. It contributes to red blood cell formation and the development of new cells. A deficiency in folate can cause a pigment change in your nails and make them rigid and brittle. Foods rich in folate include dark green vegetables, citrus fruits, beans, peas, lentils, nuts, seeds, and avocado.
Vitamin B, especially B7 and B9, helps supply essential fatty acids to nails, keeping them hydrated and improving their texture. The omega fatty acids in camel milk, for example, can keep nails moisturized and shiny while also promoting nail growth.

Vitamin E is an ultra-hydrating antioxidant that helps heal and promote new nail growth
Vitamin E is a powerful antioxidant that helps heal and promote new nail growth. It is an ultra-hydrating oil that nourishes the nails and the skin around them. Vitamin E oil can be applied to the nails and cuticles to increase nail flexibility, improve texture, and prevent cracked cuticles and dry skin.
Vitamin E is a fat-soluble nutrient that comes in many forms, with the most common form being alpha-tocopheryl. It can be found in many off-the-shelf nail oils and hand creams. It is a key ingredient in products such as Sally Hansen's Vitamin E Nail and Cuticle Oil, which is designed to nourish and condition dry nails and cuticles.
Vitamin E oil can be applied directly to the nails and cuticles to increase circulation to the nail bed and stimulate new nail growth. It is recommended to apply the oil at night before bed, so it has a chance to be fully absorbed without being disturbed. It can also be applied in the morning, but it should be lightly applied to the cuticles and nails or all over the hands and nails in the form of a hand cream.
Vitamin E is particularly beneficial for those with brittle, ridged, or yellow nails, as it helps to heal and strengthen the nails while improving their appearance. It can also help to reverse damage caused by nail polish and nail polish remover, which can be drying and damaging to the nails and the surrounding skin.
Overall, Vitamin E is an important nutrient for nail health, providing hydration, protection, and stimulation of new nail growth.

Biotin, a B vitamin, helps form keratin, the main protein that makes up nails
Biotin, also known as vitamin B7, is a crucial vitamin for nail health. It helps form keratin, the protein that makes up nails, keeping them strong and preventing brittleness. As we age, the body slows down its production of keratin, which is why older people may struggle to grow long nails.
Biotin is essential for nail health because it helps to speed up nail growth and enhance nail strength. This is especially useful for people with brittle nails. In one study, participants with brittle nails were given a biotin supplement for six months, resulting in a 25% increase in nail thickness. Another study found that 63% of participants with brittle nails experienced improved symptoms after taking 2.5 mg of biotin daily for six weeks to seven months.
Biotin is found in a variety of foods, including eggs, nuts, seeds, salmon, avocados, and dark, leafy greens. It is also present in organ meats, such as liver, dairy products, yeast, sweet potato, and cauliflower. For vegetarians who may not consume enough biotin through their diet, taking a supplement can be beneficial for nail health.
While biotin plays a key role in nail health, other vitamins and minerals are also important. Vitamin C, for example, is necessary for the production of collagen, which gives structure and strength to nails. Vitamin E provides hydration to the nail beds and skin, helping with new nail growth and reducing yellowing. Zinc is also crucial for healthy nails, as it supports cell growth and protects nails from damage.

Folate, a B vitamin, helps create healthy red blood cells, which carry oxygen to the nail beds
Healthy nails are an indication of overall good health. Nutrient deficiencies can affect the appearance of your nails. One of the essential vitamins for nail health is folate, a type of B vitamin.
Folate helps create healthy red blood cells, which carry oxygen to the nail beds. This oxygen is vital for nail health. Deficiencies in folate can lead to nail discolouration, ridges in your nails, and even make nails brittle and rigid.
Folate is also important for cell growth and DNA synthesis. It helps the body produce new cells, and a lack of it can lead to megaloblastic anaemia, which can cause nails to become brittle and break easily.
The recommended daily allowance of folate for adults is 400mcg. Foods rich in folate include beef liver, spinach, black-eyed peas, fortified breakfast cereals, asparagus, and Brussels sprouts. If you don't like liver and leafy greens, you may want to consider taking a supplement to ensure optimal nail health.
Other vitamins and minerals are also important for nail health, including vitamins A, B, C, D, and E, as well as minerals like iron, zinc, calcium, and magnesium. A well-rounded, nutrient-rich diet is the best way to achieve strong and healthy nails.
