Strong, healthy nails and hair are a result of a healthy body. A well-rounded diet that includes vitamins, minerals, and other nutrients is essential to achieving this. Vitamin C, for example, is necessary for the production of collagen, which is a key structural component of hair and nails. A deficiency in vitamin C can lead to weaker hair and nails. Similarly, vitamin B12 and folate are important for nail and hair health, as they contribute to red blood cell formation and oxygen transportation to the nail beds and hair follicles. Biotin, also known as vitamin B7, is another essential vitamin that promotes healthy cell growth and aids in the metabolism of amino acids, which are crucial for nail and hair growth. Iron is also key, as it provides cells with oxygen, and its deficiency can lead to changes in nails and hair. While a balanced diet should provide adequate nutrition, supplements can be considered if dietary intake is insufficient.

What You'll Learn
Vitamin C for nail and hair strength
Vitamin C is an essential nutrient for nail and hair strength. It is required for the production of collagen, a protein that gives shape, strength, and structure to many tissues in the body, including fingernails and hair. Collagen acts as the structural foundation, providing strength, shape, and resistance to breakage. A deficiency in vitamin C can lead to weaker hair prone to breakage and brittle nails.
The recommended daily allowance for vitamin C is 90mg for men and 75mg for women, with smokers requiring an additional 35mg. Vitamin C is found in many plant-based foods, such as citrus fruits (oranges, grapefruit, and kiwi), strawberries, bell peppers (especially red bell peppers), tomatoes, broccoli, and leafy green vegetables.
In addition to its role in collagen production, vitamin C is also important for iron absorption. Iron is necessary for healthy nails, and vitamin C helps ensure that the body can utilize this mineral effectively. By promoting healthy iron absorption, vitamin C contributes to stronger nails and hair.
Vitamin C also has benefits for the hair and scalp. It enhances shine, moisturizes, and helps retain hair colour. Additionally, its antioxidant properties help neutralize free radicals, reducing the onset of wrinkles, fine lines, and skin dryness.
While vitamin C is crucial for nail and hair health, it is important to note that it is a water-soluble vitamin, and the body does not store it. Therefore, a consistent daily intake of vitamin C is essential to maintain its benefits.

Biotin for nail and hair health
Biotin, also known as vitamin B7, is a water-soluble vitamin that has gained popularity in the beauty industry for its role in promoting healthy skin, hair, and nails. It is an essential cofactor for carboxylase enzymes in multiple metabolic pathways and supports the metabolism of protein-building amino acids that are crucial for nail growth.
While biotin deficiency is rare, it can lead to thinning hair and brittle nails. However, it is important to note that thinning hair or brittle nails are usually caused by other health conditions, such as iron deficiency or thyroid issues. Biotin-rich foods include meat, eggs, fish, liver, salmon, pork, nuts, and seeds. For vegetarians who may not consume enough biotin through their diet, supplements are available.
Several studies have shown that biotin supplementation improves hair and nail growth in individuals with underlying conditions affecting hair and nail health. However, there is limited research and conflicting evidence regarding the effectiveness of biotin supplementation in healthy individuals. While some people report that biotin supplements boost their hair and nail growth, no studies have proven that biotin supplements change the appearance of hair, skin, or nails.
In addition to biotin, other vitamins and nutrients are important for nail health. Vitamin C is essential for collagen production, which provides strength and structure to nails. Iron is also crucial, as it ensures that nail cells receive adequate oxygen, and a deficiency can lead to nail ridges or concavity. Vitamin B12 and folate (vitamin B9) contribute to red blood cell formation and oxygen transportation to the nail beds.

Iron to prevent nail ridges
Ridges in your fingernails can be caused by various factors, ranging from stress to thyroid disease, and are usually harmless. However, they can also indicate a health condition or nutrient deficiency. One such nutrient deficiency that can cause vertical nail ridges is an iron deficiency.
Iron is needed to provide your cells with adequate oxygen, which is necessary for healthy nails. An iron deficiency can lead to ridges in your nails, or your nails may concave or "spoon". This condition, known as koilonychia, presents as a depression in the middle of the nail, as if the center of the nail had been scooped out.
The recommended daily allowance of iron for adults varies depending on age and gender. Men require 8 mg per day, while women aged 19-50 require 18 mg. After menopause or the age of 50, women's iron needs drop to 8 mg daily. Iron can be found in animal foods such as beef, chicken, fish, and eggs, as well as plant foods like dark green leafy vegetables, peanuts, seeds, and beans. However, the body absorbs iron from animal sources better than plant sources. Combining plant-based iron sources with foods rich in vitamin C, such as oranges, strawberries, and bell peppers, can improve iron absorption.
If you suspect that your nail ridges are due to an iron deficiency, it is important to consult a healthcare provider to determine the underlying cause and rule out any health conditions. Taking iron supplements, with your provider's guidance, may help address the deficiency and improve the appearance of your nails over time. It is worth noting that it takes several months for nails to grow out, so it will take time to see improvements in nail ridges.

Vitamin A for nail and hair growth
Vitamin A is a cornerstone supplement for beauty needs, keeping hair and nails healthy and growing. It regulates cells, ensuring they're growing properly. This regulation of cells is what makes it a cornerstone supplement for our beauty needs. Vitamin A also plays a role in sebum production, which is the natural oil that your scalp produces, acting as a built-in conditioner to keep your hair from turning into a dry, brittle mess.
Vitamin A acts as a nurturing force, offering a foundation for robust hair and nails. It can be a game-changer, providing the nutrients needed for your hair and nails to thrive. Think of it as the principal gardener, encouraging your cells to grow lush and vibrant.
However, balance is key. Too much vitamin A (above 1.5 mg per day) can be counterproductive, so it's all about finding that sweet spot. Vitamin A can be found in products like those from TYME, or it can be integrated into your diet.
Biotin is also a popular supplement for hair and nail growth. It is a B vitamin that may help promote hair strength and growth for people who are deficient in the nutrient. It is also beneficial for those with brittle nails. Biotin is mostly found in meat, eggs, fish, seeds, and nuts. So, if you are a vegetarian and you don’t eat a lot of nuts and seeds, you may consider adding a biotin supplement to keep your nails looking their best.

Folate to prevent nail discolouration
Fingernails can be a good indicator of a person's overall health. Changes in the appearance, texture, or shape of your nails could indicate nutrient deficiencies. One of the vitamins that play a role in maintaining nail health is folate, also known as vitamin B9.
Folate is important for nail growth and health by contributing to red blood cell formation and the development of new cells. A deficiency in folate can cause nail discolouration and make nails rigid and brittle. It is recommended that adults get 400 mcg of folate per day, although pregnant women have an increased need for this vitamin.
Folate can be found in a variety of foods, including dark green vegetables, citrus fruits, beans, peas, lentils, nuts, seeds, and avocado. However, if a person's diet does not include enough of these foods, they may need to consider taking a folate supplement to prevent nail discolouration and other nail health issues.
In addition to folate, there are several other vitamins and nutrients that are important for nail health. These include vitamin C, zinc, biotin, and iron. Vitamin C is essential for the production of collagen, which is a building block for nails, providing them with strength and integrity. Zinc is important for the healthy growth and replication of cells, and a deficiency can lead to issues with the nail bed and white spots on the nails. Biotin is a B-complex vitamin that promotes healthy cell growth and aids in the metabolism of protein-building amino acids that are essential for nail growth. Iron is also important for nail health, as it provides cells with adequate oxygen, and a deficiency can lead to vertical ridges in the nails or nails that concave or "spoon".
By ensuring an adequate intake of folate and other key nutrients, individuals can help maintain nail health and prevent issues such as discolouration, brittleness, and ridges.
