Strong, healthy nails require a nutritious diet. Nutrient deficiencies can affect nail growth and strength, and a change in the appearance, texture, or shape of your nails could indicate a nutrient deficiency. Nails are made of the protein keratin, so a diet that includes plenty of protein like lean meats, chicken, turkey, and eggs can help your nails repair, grow, and maintain their strength. Salmon is also a great option as it is rich in fatty acids and vitamin B12, which promotes healthy cell growth and red blood cell development. For plant-based diets, beans, legumes, tofu, nuts, quinoa, and vegetables offer just as much protein as animal sources. In addition, oranges, bell peppers, and other citrus fruits are packed with vitamin C, which helps your body produce collagen, a protein used to build strong nails.

Eat salmon, fatty fish, and eggs for vitamin D and protein
Salmon, fatty fish, and eggs are excellent sources of vitamin D and protein, which are essential for healthy nails. Vitamin D and protein work together to support nail health and promote strong and shiny nails.
Salmon is a fatty fish that is widely known for its high vitamin D content. While wild-caught salmon typically contains more vitamin D than farmed salmon, both varieties are rich in this essential nutrient. Additionally, salmon is an excellent source of high-quality protein, providing 22-25 grams of protein per 3.5-ounce (100-gram) serving. This makes it a valuable food choice for those seeking to improve their nail health.
Fatty fish, in general, are good sources of vitamin D. This includes various species of salmon, such as Salmo salar from the Atlantic Ocean, and Oncorhynchus sp. from the Pacific Ocean. By incorporating these fatty fish into your diet, you can boost your vitamin D intake and promote overall nail health.
Eggs are another excellent source of both vitamin D and protein. Vitamin D is found in egg yolks, and the amount of vitamin D in eggs can be increased by adding vitamin D to the feed of hens or exposing them to UVB light. Choosing eggs from chickens raised outdoors or marketed as high in vitamin D can be a strategic way to meet your daily vitamin D requirements and support nail health.
In addition to their high vitamin D and protein content, salmon and other fatty fish provide essential omega-3 fatty acids. These healthy fats play a crucial role in reducing inflammation, lowering blood pressure, and supporting brain health. By including salmon and fatty fish in your diet, you can nourish your nails from within, promoting their strength and shine.

Consume biotin-rich foods like eggs, nuts, and liver
Consuming biotin-rich foods is an excellent way to promote nail growth and health. Biotin, also known as vitamin B7, 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. While biotin supplements are available, incorporating biotin-rich foods into your diet is a natural way to increase your biotin intake and support the health of your nails.
Eggs are an excellent source of biotin, with the vitamin concentrated in egg yolks. They are also a good source of protein, which can boost nail strength and speed up growth. Meat lovers can also opt for leaner options like chicken and turkey, which provide collagen and are high in protein, both crucial for nail health. Organ meats, such as liver, contain the highest concentration of biotin. While liver might not be everyone's favourite food, including it in your diet can provide a significant boost of this nail-strengthening vitamin.
Nuts are another great source of biotin. Whether you prefer almonds, walnuts, or Brazil nuts, snacking on a handful of nuts can provide your body with the biotin it needs to support nail health. Nuts are also a good source of protein, especially beneficial for those who follow a plant-based diet. Quinoa is another plant-based option that provides protein and ensures your body has the building blocks it needs for strong nails.
In addition to these biotin-rich foods, remember that hydration is crucial for nail health. Water allows the body to function properly and supports the growth of healthy nails. So, while you're snacking on nuts and reaching for that egg, don't forget to drink a glass of water, too!

Vitamin C and collagen-rich foods like oranges and peppers prevent brittle nails
Vitamin C and collagen are both essential for healthy nails. While collagen is the most abundant protein in the human body, providing structure, strength, and support, our bodies cannot absorb collagen in its whole form. Instead, our bodies break down the collagen proteins we eat into amino acids.
Vitamin C is crucial for collagen synthesis, and a deficiency in this vitamin can affect nail growth and strength. Citrus fruits like oranges, grapefruits, and kiwis are rich sources of vitamin C. Additionally, red and green peppers, broccoli, kale, and Brussels sprouts are also vitamin C-rich foods that can contribute to collagen production.
To boost collagen levels, focus on consuming protein-rich foods, whether from plant or animal sources. Chicken, fish, bone broth, and egg whites are excellent sources of collagen. For plant-based options, nuts, seeds, beans, legumes, and tofu are great choices. Organ meats, such as liver, are also rich in biotin, which is essential for nail health.
In addition to vitamin C and collagen-rich foods, staying properly hydrated is crucial for nail health. Water plays a vital role in keeping the body functioning optimally, which includes supporting nail growth and strength. So, while enjoying those vitamin C-rich oranges, don't forget to drink plenty of water for happy and healthy nails!

Nuts, seeds, and avocados provide healthy fats and magnesium
If you want your nails to grow shinier and stronger, you should add more nuts, seeds, and avocados to your diet. These foods are rich in healthy fats, which help supply the body with magnesium—an essential mineral for bone and nail health.
Nuts are a great source of protein, which is crucial for nail strength and resilience. They also contain selenium, a vital mineral that fuels protein enzymes and prevents cell damage. Just one Brazil nut provides twice your daily selenium requirements, as well as zinc, B-vitamins, and vitamin E. Selenium helps prevent nail discoloration and ridges, improving the overall appearance and shine of nails.
Seeds are another great source of healthy fats, protein, and omega-3 fatty acids, which can help lubricate and moisturize your nails, giving them a shiny appearance. They also contain vitamin E, which encourages healthy nail growth and gives nails a natural luster.
Avocados are also a good source of omega-3 fatty acids, which can help moisturize nails and protect them from feeling flimsy or dry. They also contain vitamin E, which encourages healthy nail growth and gives nails a natural shine. In addition, avocados provide biotin, a B vitamin that contributes to the production of keratin, which is what nails are made of.
By including nuts, seeds, and avocados in your diet, you can provide your body with the healthy fats, magnesium, and other essential nutrients it needs to support nail health and promote strong and shiny nails.

Iron-rich foods like meat, spinach, and beans prevent nail discolouration
Iron-rich foods are essential for maintaining strong and healthy nails. While iron is most commonly associated with energy, it is also crucial for nail health. A deficiency in iron can lead to iron-deficiency anaemia, which can manifest as koilonychia, a condition characterised by thin nails with raised ridges.
Meat, such as chicken and turkey, is a rich source of iron and provides the protein necessary for nail growth and strength. For those who prefer plant-based sources of iron, spinach, kale, arugula, watercress, and collards are excellent choices. These leafy greens are packed with iron, folate, and calcium, all of which contribute to stronger nails. Additionally, beans are an excellent vegan option, providing both protein and iron to support nail health.
Including these iron-rich foods in your diet can help prevent nail discolouration, which is often a sign of vitamin B12 deficiency. Vitamin B12 is necessary for the development of healthy red blood cells, and its absence can lead to brown or grey discolouration of the nails.
In addition to iron-rich foods, a well-rounded diet that includes a variety of fruits, vegetables, nuts, and seeds can further enhance nail health. Ensuring adequate hydration by drinking enough water and consuming hydrating liquids is also vital for strong and healthy nails.
