Healthy nails are a sign of good overall health. What you eat has a big impact on the health of your nails. Eating nutrient-dense foods can improve the appearance of your nails. Consuming enough vitamins, minerals, and micronutrients can encourage healthy nail growth. For example, vitamin C is essential for collagen production, which is important for strong nails. Vitamin C also helps your body absorb iron, which is necessary for healthy nails. Vitamin E is another important antioxidant for healthy nail growth, as it helps protect cells from damage. Biotin is also important for nail growth, as it helps boost keratin production and improves nail strength and thickness. Foods such as eggs, salmon, leafy greens, nuts, and seeds are all great sources of these vitamins and minerals and can help promote healthy nail growth.

What You'll Learn

Eat eggs for biotin and vitamin D
Eating nutrient-dense foods is key to encouraging strong nail growth. Nails, like the rest of the body, require a nutritious diet to thrive. If you are malnourished, have a vitamin or mineral deficiency, or are not consuming enough protein, your nails may become weak, brittle, or slow to grow.
One food group that can help promote nail growth is eggs. According to celebrity manicurist Deborah Lippmann, eggs are a fantastic food for stronger and shinier nails. They are high in protein, vitamin D, B12, and biotin, all of which contribute to nail growth.
Protein aids in the formation of keratin, which is critical for developing stronger nails. Biotin helps with nail thickness, and a deficiency can lead to brittle nails. Vitamin D is also essential for nail health, and a deficiency can cause dry and brittle nails.
In addition to eggs, you can also find biotin in organ meats, salmon, pork, beef, seeds, nuts, and sweet potatoes. Vitamin D can be found in fatty fish like salmon, and exposure to sunlight can also help your body produce this vitamin.
While diet is important, it is also crucial to stay hydrated for nail health. Water and other hydrating liquids help keep your nails from becoming brittle and breaking easily.

Consume fatty acids like salmon, flaxseed, nuts and seeds
Consuming fatty acids is an important part of maintaining healthy nails. Fatty acids help to prevent nails from becoming brittle and keep them moisturised. Salmon is a great source of omega-3 fatty acids, which also help to reduce inflammation in the body, improving nail health and appearance. Salmon is also a good source of vitamin B12, which is required for the development of healthy red blood cells and can prevent nail discolouration.
Flaxseed is another food that is rich in omega-3 fatty acids and thiamine, which has been linked to improved hair and nail health. Flaxseed is also a good source of magnesium, which is essential for maintaining nail health and preventing the formation of ridges on the nail bed. If you don't eat fish, flaxseeds are a great alternative for getting those fatty acids.
Nuts and seeds are also excellent sources of fatty acids and protein, biotin, and vitamin E, all of which are important for healthy nails. Vitamin E is an antioxidant that helps protect cells from damage, while biotin is a B vitamin that is essential for nail growth. Nuts and seeds also provide the body with magnesium, which is necessary for bone and nail health.
Overall, consuming fatty acids through foods like salmon, flaxseed, nuts, and seeds is a great way to support the health and appearance of your nails. These foods provide the body with the nutrients it needs to grow strong, healthy nails and can help prevent common nail issues like brittleness and discolouration.

Get vitamin C from strawberries, oranges and leafy greens
Vitamin C is essential for collagen production, which helps provide strength and integrity to your nails. It also plays a role in improving iron absorption. To improve nail growth, try eating more vitamin C-rich foods, such as strawberries, oranges, and leafy greens.
Strawberries are a delicious snack and are high in antioxidants, which rid the body of free radicals that can damage healthy cells. Oranges are also an excellent source of vitamin C and can be easily added to your diet. Try having a glass of orange juice with your breakfast or eating an orange as a snack.
Leafy greens such as kale, arugula, watercress, spinach, and collards are great sources of vitamin C and can provide your body with enough iron, folate, and calcium to keep your nails strong and healthy. Try adding a spinach salad with beans and seeds to your diet to improve your iron absorption and nail health.
In addition to vitamin C, remember that hydration is crucial for nail health. Drink plenty of water throughout the day and include hydrating foods such as fruits, vegetables, yogurt, and soups.

Drink water and stay hydrated
Drinking water and staying hydrated are essential for nail health. Nails are made up of about 18% water, so when the body is dehydrated, the nails become brittle. Dehydration can also cause ridges in the nail bed, which can be prevented by consuming more magnesium.
Water helps maintain the balance of electrolytes and minerals in the body, which are crucial for nail growth. Proper hydration ensures a steady supply of nutrients to the nails, promoting growth and reducing the risk of common nail issues. It also supports keratin production, making nails strong and flexible.
To maintain adequate hydration, it is recommended to drink around eight glasses of water per day. However, individual factors such as activity level, climate, and overall health can affect water needs. It is important to listen to your body and drink when thirsty, but also to establish a routine that encourages regular water consumption throughout the day. Incorporating hydrating foods, such as cucumbers, watermelon, and oranges, can also contribute to overall hydration levels.
While drinking water is important, it is worth noting that water can weaken the nails if they are exposed to it for too long, making them soft and brittle. Therefore, it is recommended to dry the nails thoroughly after swimming or showering and to wear gloves when washing dishes or cleaning.
In addition to hydration, a well-balanced diet that includes protein, water, fruits, vegetables, and a variety of vitamins and minerals is crucial for nail health and growth. Specific dietary changes, such as increasing protein intake and consuming nutrient-dense foods, can strengthen the nails and promote growth.

Get zinc to support cell growth and repair
To support nail growth, it is important to consume nutrient-dense foods. Nails, like the rest of the body, require a nutritious diet to thrive. Zinc is a mineral that is essential for many of the body's normal functions and systems. It is especially important to support normal growth and development during pregnancy, childhood, and adolescence.
Zinc is found in many foods, but the body absorbs zinc from animal-based foods better than plant-based sources. The best source of zinc is oysters, but it is also plentiful in red meat, poultry, and other seafood. Other good sources include whole grains, legumes, nuts, seeds, and dairy products. Zinc-rich plant foods include beans, nuts, seeds, and whole grains.
Zinc plays a role in cell growth, collagen formation, and inflammatory responses, making it essential for proper wound healing. It also supports the body's normal growth and development, including bone growth. The Recommended Dietary Allowance (RDA) for zinc is 11 milligrams (mg) per day for adult men and 8 mg per day for adult women. For pregnant or lactating women, the RDA is 11 mg and 12 mg per day, respectively. Adults should not exceed 40 milligrams of zinc per day from all sources, including supplements.
In addition to zinc, fatty acid-rich foods encourage healthy cell development, which aids in nail growth. Salmon, for example, is rich in fatty acids and helps maintain cell growth, promoting healthy nails and hair. Eggs are another excellent food choice for nail growth, as they are high in protein, vitamin D, B12, and biotin, contributing to stronger and thicker nails.
