Strong, healthy nails are an indicator of overall health. 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. Vitamins that promote nail growth include vitamin C, vitamin E, vitamin B, vitamin B7, vitamin B9, vitamin B12, vitamin D, vitamin A, and biotin. Additionally, minerals such as iron, zinc, and calcium are important for nail health. A well-rounded diet that includes a variety of fruits, vegetables, nuts, seeds, and adequate protein and omega-3 fatty acids is essential for maintaining strong and healthy nails.

Vitamin C helps produce collagen, which is a building block for nails
Vitamin C is essential for nail health and growth. It helps produce collagen, which is a key structural protein in our tissues. Collagen is the main component of nails, hair, skin, tendons, cartilage, and bones. It works with other substances, such as hyaluronic acid and elastin, to maintain skin elasticity and moisture.
Collagen is naturally produced by our bodies using amino acids from protein-rich or collagen-rich foods. However, factors such as aging, sun damage, smoking, and alcohol consumption can decrease collagen production. This reduced collagen production can lead to dry and brittle nails.
To promote nail growth and strength, ensuring adequate intake of vitamin C is crucial. Vitamin C can be found in fruits and vegetables, including bell peppers, oranges, kiwis, and broccoli.
In addition to vitamin C, other nutrients such as zinc, biotin, and vitamin B also play important roles in nail health. A well-rounded diet that includes a variety of fruits, vegetables, nuts, seeds, and adequate protein can contribute to stronger and healthier nails.
While collagen supplements have gained popularity, the evidence of their effectiveness is limited. Some studies suggest that collagen supplements may provide benefits, but more extensive research is needed to confirm their impact on nail health.

Biotin supplements can help restore and strengthen brittle nails
Biotin, also known as vitamin B7, is a water-soluble nutrient that metabolises fatty acids, glucose, and amino acids. It is a vitamin that helps the body perform several important functions, such as converting food into energy. Biotin is essential for promoting healthy cell growth and aiding in the metabolism of protein-building amino acids, which are crucial for nail growth.
Biotin supplements are often recommended for individuals with brittle nails, as they can help restore and strengthen them. Studies indicate that consuming 2.5 mg (2,500 mcg) of biotin daily may enhance nail firmness, hardness, and thickness. In one particular study, over half of the participants taking 2.5 mg of biotin daily experienced a 25% increase in nail thickness. While these initial findings are promising, more extensive research is required to conclusively prove the efficacy of biotin in strengthening nails.
Biotin-rich foods, such as sweet potatoes, salmon, eggs, and beef liver, can also help strengthen brittle nails. However, for individuals who may not obtain sufficient biotin from their diet alone, biotin supplements offer a convenient way to boost their intake. These supplements are generally considered safe, with most people not experiencing any adverse effects when taking regular amounts.
In addition to biotin, other vitamins and minerals also play a crucial role in nail health. Vitamin C, for instance, is essential for collagen production, which provides strength and integrity to nails. Zinc is another important nutrient, as it is required for the growth and division of cells, including nail cells, which grow and divide rapidly. Nails that grow with ridging may indicate an iron deficiency, as iron is essential for keeping nail beds healthy and ensuring proper oxygen supply to the nails.
Overall, maintaining a well-rounded diet that includes a variety of fruits, vegetables, nuts, and seeds, as well as adequate protein and omega-3 fatty acids, is key to promoting nail health and supporting their growth and strength. While biotin supplements can be beneficial for individuals with brittle nails, it is always advisable to consult with a healthcare professional or a dermatologist to determine the best course of treatment for your specific needs.

Folate contributes to tissue integrity and healthy cell growth
Healthy nails indicate a healthy body. Fingernails constantly give rise to nail tissue, and adequate vitamin, mineral, and nutrient intakes help support the growth, formation, and strength of new nail cells. A change in the appearance, texture, or shape of your nails could indicate nutrient deficiencies.
Folate, or vitamin B9, is important for nail growth and health. It contributes to tissue integrity and healthy cell growth, cell division, and DNA. Changes in nails are one of many signs of folate deficiency, which gives nails a "ridge". Folate can be found in many plant-based foods, including spinach, asparagus, Brussels sprouts, and fortified breakfast cereal. It is also present in dark green vegetables, citrus fruits, beans, peas, lentils, nuts, seeds, and avocado.
Folate is important for cells and tissues that divide rapidly. Both adults and children need folate to make normal red and white blood cells and prevent anemia, which causes fatigue, weakness, and an inability to concentrate. Folate is also essential for the proper development of the embryo and fetus.
Folate deficiency may lead to glossitis, diarrhea, depression, confusion, anemia, fetal neural tube and brain defects, and poor growth. Folate deficiency in children may develop within a month of poor dietary intake. In adults, normal total body folate is between 10 and 30 mg, with about half of this amount stored in the liver and the remainder in blood and body tissues.
Other vitamins that contribute to nail growth include vitamin C, vitamin E, vitamin B, vitamin A, and biotin.

Iron deficiencies can cause brittle nails or ridges
While there are several vitamins and nutrients that contribute to nail growth and health, iron deficiencies are specifically associated with brittle nails and ridges.
Iron composes the centre of red blood cells, which carry oxygen to your organs and every cell in your body, including your nails. A deficiency can cause hair loss and nail abnormalities. For instance, iron deficiency anaemia can cause koilonychia, which thins nails with raised ridges, and nails tend to curve inward. Nails with ridges that grow in this manner are most likely linked to an iron deficiency.
In addition, spoon nails, where the centre of the nail becomes sunken, giving a spoon-like appearance, are also associated with iron deficiency. Spoon nails can also be thin and brittle.
To treat iron deficiencies, you can try adding iron-rich foods to your diet. However, some sources advise against iron supplements unless you know you are deficient. Instead, it is recommended to start taking a multivitamin that includes calcium and B vitamins.

Zinc deficiencies can cause white spots on nails and slow growth
While there are several vitamins and nutrients that contribute to healthy nail growth, zinc plays a crucial role in maintaining strong and healthy nails. A deficiency in zinc can lead to various nail-related issues, including white spots and slow nail growth.
Zinc is an essential mineral that supports numerous functions in the body, including growth. It is required for the growth and division of cells, which is particularly important for nails as they are made up of rapidly growing and dividing cells. Therefore, a steady supply of zinc is necessary to promote healthy nail growth.
A zinc deficiency can cause a degeneration of the nail plate, resulting in the appearance of white spots on the nails. This condition is known as leukonychia, and it is a common occurrence that usually does not indicate a serious medical issue. However, it is important to note that white spots on the nails can also be caused by injuries to the nail matrix, allergies, fungal infections, mineral deficiencies, or heavy metal poisoning.
In addition to causing white spots, zinc deficiency can also lead to slow nail growth. Nails may become brittle and fragile, making them more susceptible to cracking and splitting. Beau's lines, which are horizontal grooves across the fingernails, can also develop due to zinc deficiency. These lines indicate a disruption in the area where nail growth starts, further contributing to slow nail growth.
To prevent zinc deficiency, it is important to include zinc-rich foods in your diet. Animal proteins such as meat, poultry, fish, and eggs are excellent sources of zinc. However, for those following a vegetarian or vegan diet, certain plant foods like soy, chickpeas, black beans, nuts, and seeds also contain zinc. Ensuring adequate intake of these foods can help maintain healthy nail growth and prevent issues related to zinc deficiency.
