While it is common knowledge that calcium is crucial for strong bones, it may come as a surprise that it also plays a vital role in nail health. This article will discuss the best foods to include in your diet for healthy nails.

Protein is another key nutrient required for healthy nails. Keratin, the main structural component of hair and nails, is a type of protein. A diet lacking in protein can lead to weak and brittle nails that are prone to breaking easily. Additionally, biotin, a B-vitamin found in many protein-rich foods such as eggs and meat, has been shown to improve nail strength and thickness.

By including these essential nutrients in your diet through whole food sources, you can improve the appearance and strength of your nails while also promoting overall health.

Calcium For Nail Strength

Calcium is an essential mineral that contributes to the growth and strength of nails, making it one of the best nutrients for healthy nails.

In fact, calcium deficiency can lead to brittle and weak nails, which are more prone to breakage and damage.

Incorporating calcium-rich foods into your diet, such as dairy products like milk, cheese, and yogurt or leafy greens like kale and spinach, can help maintain the structural integrity of your nails.

Additionally, supplementing your diet with calcium supplements may also be beneficial in promoting nail health.

However, it is important to consult a healthcare professional before taking any supplements to ensure they are safe and effective for you.

Protein For Keratin Production

Protein plays a vital role in the production of keratin, which is a major component of nails.

Incorporating protein-rich foods into one’s diet can promote healthy nail growth and prevent brittleness and breakage.

Good sources of protein for keratin production include lean meats such as chicken, turkey, and fish, as well as plant-based options like beans, lentils, nuts, and seeds.

It is important to consume a variety of protein sources to ensure that all essential amino acids are obtained for optimal nail health.

Additionally, incorporating vitamin C-rich foods such as citrus fruits, berries, and bell peppers can aid in the absorption of iron from plant-based proteins to further support healthy nail growth.

B-Vitamins For Nail Thickness

B-Vitamins are essential for promoting nail thickness and growth, as they are present in vitamin B complex, biotin, folic acid, vitamin B12, vitamin B6, vitamin B3, vitamin B2, vitamin B1, iron, zinc, selenium, and magnesium. These vitamins and minerals play an important role in providing the nails with essential nutrients for growth and thickness.


Nails are a reflection of overall health, and a poor diet can lead to brittle and weak nails.

B-vitamins play a vital role in maintaining nail thickness. Specifically, biotin (vitamin B7) is essential for the production of keratin, a protein that makes up nails, hair, and skin.

Additionally, vitamin B12 supports healthy red blood cell production, which is necessary for delivering oxygen and nutrients to nail cells.

Other B-vitamins such as thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), and pyridoxine (B6) also contribute to overall nail health by promoting proper circulation and tissue repair.

Consuming foods rich in these vitamins such as eggs, nuts, leafy greens, whole grains, and lean meats can help maintain strong and healthy nails.

Nail Thickness

Maintaining adequate nail thickness is an important aspect of overall nail health.

B-vitamins have been found to play a crucial role in maintaining healthy nail thickness.

Along with biotin, which is essential for the production of keratin, the protein that forms nails, hair, and skin, other B-vitamins such as thiamine, riboflavin, niacin, pantothenic acid, and pyridoxine contribute to maintaining strong and healthy nails by promoting proper circulation and tissue repair.

Consuming foods rich in these vitamins can help ensure that the body has sufficient amounts to maintain optimal nail thickness.

Iron For Nail Growth

Iron is an essential nutrient for healthy nail growth and maintenance. It plays a vital role in the production of hemoglobin, a protein that carries oxygen to the nails and other parts of the body.

Insufficient iron intake can lead to brittle, weak nails that are prone to breaking and splitting. In severe cases, iron deficiency can cause a condition called koilonychia, where the nails become thin and concave with raised edges.

To maintain healthy nails, it is recommended to include iron-rich foods in your diet such as red meat, poultry, fish, beans, lentils, tofu, fortified cereals, spinach, kale, and broccoli.

It is important to note that excessive intake of iron supplements can be harmful and should only be taken under medical supervision.

Zinc For Nail Health

Iron is undoubtedly essential for the growth of healthy nails.

However, zinc also plays a crucial role in maintaining nail health.

Zinc helps to strengthen the nail plate and prevent brittleness and breakage.

It also aids in the production of new cells and promotes healing of damaged tissue around the nail bed.

Zinc deficiency can result in white spots on nails, which may indicate poor absorption of nutrients.

Foods rich in zinc include oysters, beef, pumpkin seeds, cashews, and spinach.

While both iron and zinc are necessary for healthy nails, it is important to maintain a balanced diet that includes a variety of nutrients to ensure overall health and well-being.


Healthy nails are a reflection of overall health and well-being. Consuming a balanced diet that includes essential nutrients can significantly enhance the strength, thickness, and growth of nails.

Calcium is vital for nail strength as it helps to maintain healthy bones and teeth. Additionally, protein is necessary for keratin production, which is a major component of nails.

B-vitamins play a crucial role in nail thickness and health. They help the body generate new cells, including those that form nails. Iron is also important for nail growth since it carries oxygen to the cells and promotes cell division. Zinc contributes to healthy nail growth by supporting collagen formation.

Incorporating these nutrients into one’s diet can have significant benefits for nail health. A varied diet with plenty of fruits, vegetables, lean proteins, and whole grains is ideal for supporting healthy nails. Adequate hydration is also key for nail health as dehydration can lead to brittle and weak nails.

In conclusion, consuming nutrient-dense foods that contain calcium, protein, B-vitamins, iron, and zinc can effectively promote healthy nails. By incorporating these foods into our diets daily while also staying hydrated, we can achieve strong, thick nails that reflect overall good health.

As the saying goes: ‘You are what you eat,’ so let us consume wisely to enjoy healthy and beautiful nails!
