Eat foods rich in protein, like eggs, chicken, turkey, fish, beans, legumes, and tofu
Eating foods rich in protein is essential for strong nails. Nails are made of a protein called keratin, so it is important to eat enough protein to keep your nails healthy and strong.
Eggs are a fantastic source of protein and are also high in vitamin D, B12, and biotin, making them an excellent choice for nail growth. They are also a source of sulfur and healthy fats. Vitamin D helps regulate calcium levels, which helps your nails (and bones) grow strong. Biotin helps with nail thickness.
Chicken and turkey are lean protein sources that provide collagen and are high in protein, both of which are crucial to nail health.
Fish, such as salmon, is another great source of protein and healthy fats, which will help you grow shiny, strong nails. Salmon is also a natural source of vitamin D and omega-3 fatty acids, which are good for your brain.
Beans, legumes, and tofu are excellent plant-based sources of protein. They are also a good source of iron, which prevents anemia, a condition that can affect nail health.
In addition to protein, it is important to stay hydrated by drinking enough water and eating hydrating foods. This helps deliver nutrients and oxygen to the cells and keeps your nails and cuticles moisturized.

Consume vitamin D-rich foods, like eggs, to help regulate calcium levels and promote nail growth
Strong nails are an indicator of a healthy diet and lifestyle. A deficiency in vitamins and minerals will often show up as changes in the texture, strength, and appearance of your nails. Vitamin D, in particular, is essential for nail health. By regulating calcium levels, vitamin D helps your nails grow strong and healthy.
Vitamin D-rich foods include eggs, fatty fish like salmon, and meat. Eggs are an excellent source of vitamin D, which is crucial for nail growth. They also contain biotin, which helps with nail thickness, and healthy fats. In fact, eggs are one of the most bioavailable protein sources, and protein is critical for maintaining strong nails. So, consider adding eggs to your diet to promote nail growth and thickness.
In addition to vitamin D, fatty acids found in salmon help maintain cell growth, promoting the growth of healthy nails. Salmon is also a good source of vitamin B12, which is necessary for nail health. Meat, poultry, and dairy are other animal-based sources of vitamin B12.
For those who follow a plant-based diet, beans, legumes, and tofu are excellent sources of protein and biotin, which are essential for nail health. Vitamin B12 can also be obtained from fortified foods. Additionally, focus on consuming iron-rich plant foods like dark, green leafy vegetables, along with vitamin C-rich foods like oranges and bell peppers to enhance iron absorption.
Overall, a diet rich in vitamin D, protein, biotin, and other essential nutrients will promote nail growth and overall nail health.

Include biotin-rich foods, like eggs, nuts, leafy greens, and fortified cereals, to improve nail thickness and reduce splitting
Strong and healthy nails are a reflection of your overall health. A diet rich in nutrients is essential for nail growth, and biotin is one such nutrient that can help improve nail thickness and reduce splitting.
Biotin, also known as vitamin B7, is an essential water-soluble nutrient that supports your metabolism by helping convert food into energy. It is also touted to improve hair, skin, and nail health. While biotin supplements are available, it is always advisable to obtain this nutrient from your diet.
Foods rich in biotin include eggs, nuts, seeds, salmon, pork, and liver. Eggs, in particular, are a fantastic food for stronger and shinier nails as they are also a good source of protein, vitamin D, and B12, in addition to biotin. Vitamin D helps regulate calcium levels, which in turn aids in growing strong nails and bones.
In addition to biotin-rich foods, leafy greens like kale, arugula, watercress, spinach, and collards can supply you with enough iron, folate, and calcium to keep your nails strong and prevent splitting. Fortified cereals are another option to include biotin in your diet.
By incorporating these biotin-rich foods into your diet, you can support the health of your nails and improve their thickness and resilience, reducing the occurrence of splitting.

Get your fill of iron from lentils, beans, beef, or bell peppers to prevent anemia and nail curvature
Strong nails require adequate oxygen, and an iron deficiency can lead to vertical ridges in your nails or nail concavity. Eating enough iron-rich foods can prevent this.
Lentils are a great source of protein and iron, both of which are essential for strong nails. They are versatile and can be added to soups, stews, salads, and curries.
Beans are another excellent source of iron and protein. They are affordable and easily incorporated into your diet. Try adding them to salads, stews, or burrito bowls for a nutritious boost.
Beef is a well-known source of iron and can be a great way to boost your iron intake. It is also a rich source of zinc, which is required for healthy nail growth.
Bell peppers are not only a good source of iron but also of vitamin C, which is necessary for iron absorption. Eating bell peppers alongside iron-rich foods like lentils, beans, or beef can significantly increase your body's ability to absorb iron.
In addition to these specific foods, it is important to maintain a balanced diet with a variety of nutrient-rich whole foods to promote overall health and nail strength.

Boost your zinc and vitamin C intake for improved cell growth and repair, and better iron absorption
Strong nails are a reflection of your overall health and vitality. They are made of a protein called keratin, so consuming adequate protein is essential for strong and resilient nails.
Zinc is a mineral that plays a crucial role in nail growth and repair. It keeps everything running smoothly by supporting cell growth and repair. A deficiency in zinc can cause nail degeneration, slow growth, nail thinning, and increased susceptibility to breakage. To promote healthy nail growth, ensure your diet includes zinc-rich foods such as red meat, poultry, fish, eggs, soy, chickpeas, black beans, wheat germ, nuts, and seeds.
Vitamin C is essential for collagen production, which helps provide strength and integrity to your nails. It also helps your body absorb iron, which is necessary for healthy nails. Iron helps bring oxygen to your cells, including your nail beds. A deficiency in iron can cause brittle nails or nails with ridges, and even spoon-shaped nails. To improve your iron absorption, pair iron-rich foods with vitamin C-rich foods like oranges, bell peppers, citrus fruits, tomatoes, potatoes, broccoli, and strawberries.
Biotin, a B-complex vitamin, promotes healthy cell growth and aids in the metabolism of protein-building amino acids that are crucial for nail growth. Foods rich in biotin include organ meats, egg yolk, dairy products, yeast, salmon, avocado, sweet potato, nuts, seeds, and even cauliflower.
