There are many factors that can affect the health of your fingernails, including your diet, lifestyle habits, and medications. While there is no one-size-fits-all answer to how fast supplements will improve your fingernails, several vitamins and nutrients are known to promote nail health and strength. Biotin, for example, is a water-soluble B-vitamin that helps to strengthen brittle nails and can be found in foods such as legumes, salmon, eggs, and supplements. Vitamin C is also important for nail health, as it is needed to produce collagen, a building block for nails. Additionally, zinc is essential for the healthy growth and replication of cells, including nail cells. However, it is always recommended to speak to your doctor before starting any new supplement, especially if you are taking medications or other supplements, to ensure they are safe and effective for you.

What You'll Learn
Biotin supplements
Fingernails can be a good indicator of a person's health, and nutrient deficiencies may affect their nails' appearance. While there are several ways to improve nail health, one popular method is the use of biotin supplements. Biotin, also known as vitamin B7, is an essential nutrient that supports metabolism and promotes healthy skin, nails, and hair.
Biotin-rich foods and supplements may help strengthen brittle fingernails and improve their growth. Biotin is found in many foods, including organ meats like liver, egg yolk, dairy products, yeast, salmon, avocado, sweet potato, nuts, seeds, and legumes. However, biotin is water-soluble, so it is not stored in the body, and consistent intake through diet or supplements is necessary.
The recommended daily intake of biotin for adults is 30 mcg, but most people get all the biotin they need from a healthy diet. Biotin supplements are available over-the-counter and are generally considered safe for most people, although mild side effects like an upset stomach may occur. It is always recommended to consult a doctor before taking any new supplement, especially if you are already taking medications or other supplements, as interactions may occur.
Some studies have shown positive results for biotin supplementation in treating brittle nails. A recent Swiss study found a 25% increase in nail plate thickness in patients with brittle nails who took biotin supplements daily over a six-month period. Another study of 35 people with brittle nails showed that 63% of participants experienced improved symptoms after taking 2.5 mg of biotin per day for six weeks to seven months.
While biotin supplements may help strengthen nails, it is important to note that other factors contribute to nail health. Adequate hydration, a proper diet, and avoiding exposure to chemicals in nail polishes, polish removers, and water can also help prevent weak nails. Additionally, keeping nails trimmed and using a moisturizing hand lotion can help maintain nail strength and hydration.

Vitamin C
Fingernails can be a good indicator of your overall health, and nutrient deficiencies may affect their appearance. Vitamin C is one of the essential nutrients that can help improve the health of your fingernails.
In addition to Vitamin C, other supplements such as biotin and zinc can also contribute to nail health. Biotin is a B-vitamin that helps maintain the health of the nervous system, hair, and nails. It can be found in foods like legumes, salmon, eggs, organ meats, dairy products, yeast, avocado, sweet potato, nuts, and seeds. Zinc is essential for the healthy growth and replication of cells, and a steady supply is needed for nail growth. Oysters, beef, crab, and lobster are good sources of zinc, while vegetarians can obtain zinc from beans and seeds or consider taking a supplement.
While supplements can help improve nail health, it is also important to take care of your nails externally. Keeping nails trimmed, avoiding using them as tools, and using a moisturizing hand lotion can help maintain their strength and prevent breakage. Additionally, staying adequately hydrated and maintaining a proper diet are crucial for nail health. If you are experiencing persistent issues with your nails, it is recommended to consult a doctor or dermatologist for personalized advice and treatment options.

Iron supplements
While consuming a variety of vitamins, minerals, and nutrients through food is the best way to improve and maintain nail health, supplements can be beneficial in certain circumstances. However, it is important to note that scientific research on the effectiveness of supplements is limited.
To ensure your nail beds are receiving adequate oxygen for healthy growth, maintaining optimal iron levels is essential. Iron is a crucial component of red blood cells, and its deficiency can affect the proper transport of oxygen to the nail beds. The recommended daily allowance of iron for adults aged 19-50 is 18mg for women and 8mg for men. After 50, women's iron requirements decrease to 8mg as well.
Food sources high in iron include iron-fortified breakfast cereals, oysters, white beans, dark chocolate, and beef liver. It is recommended to focus on improving your diet by including iron-rich foods before resorting to supplements. This is because whole foods provide additional benefits, such as phytochemicals, antioxidants, and fiber, which promote optimal nail health.
Additionally, it is important to consult a doctor or healthcare professional before taking iron supplements. Taking high doses of iron supplements without proper medical advice can be dangerous if your iron levels are already within a healthy range. It is also crucial to allow sufficient time for any supplements to take effect. On average, it takes 4-6 months for a nail to grow from the matrix to the free edge, so changes in nail health due to supplements may take several months to become apparent.

Hydration
Drinking enough water helps nails retain moisture and stay strong. The recommended daily water intake is 6 to 8 cups, and this can include tea and coffee. Proper hydration supports the health of vital organs, and when the body is dehydrated, water is directed to these organs, leaving the outermost layers of the body, including the nails, without sufficient water.
The effects of dehydration on nail health can be exacerbated by external factors and certain medical conditions. For example, exposure to water when washing dishes or taking a bath can contribute to nail dehydration, so it is advisable to wear gloves during such activities. Additionally, certain shampoos and cleaning products can contain chemicals that dry out the nails, leading to weakness and brittleness.
To maintain nail hydration, it is important to complement water intake with other moisturizing practices. This includes moisturizing the hands and nails with lotion after each hand washing and before bed. Polishing nails can also provide some protection, and when removing nail polish, it is recommended to use an acetate polish remover instead of an acetone-based one.
While hydration is crucial for nail health, it is worth noting that excessive water exposure can also negatively impact nails. Soaking nails in water for extended periods can cause them to become weak and brittle. Therefore, it is essential to strike a balance and ensure proper hydration without overdoing it.

Diet
Firstly, it is important to eat enough. If you don’t eat enough, your body will be forced to make tough decisions and direct essential nutrients to where it’s needed most, and that may not be your nails.
Secondly, a diet rich in vitamins, minerals, and micronutrients is important for nail health. Dry, cracked, and brittle nails can be a sign that you're not getting enough nutrients, while strong, shiny nails can point to a great diet and healthy lifestyle.
To improve nail health, it is recommended to eat a diet packed with vegetables, fruit, and complex carbohydrates, as well as enough protein and healthy fats.
Protein is essential as nails are made of the protein keratin. Lean meats like chicken, turkey, and fish are good sources of protein and iron, which is essential to carry oxygen to cells throughout the body, including nails. An iron deficiency can lead to concave, “spoon-shaped” nails or ridges on the surface.
Biotin is also important for nail health, improving nail thickness and reducing nail splitting. Egg yolks are an excellent source of biotin, providing approximately 33% of the recommended daily value. Other sources of biotin include organ meats, dairy products, yeast, salmon, avocado, sweet potato, nuts, seeds, and cauliflower.
Vitamin C is another essential nutrient for nail health, as it is required for collagen production, which helps provide strength and integrity to nails. While citrus fruits such as oranges, strawberries, and kiwis are thought to be the best sources of vitamin C, bell peppers, green vegetables, and tomatoes are also very high in this nutrient.
In addition, omega-3 fatty acids help lubricate nails, giving them a shiny appearance. Salmon is one of the best sources of omega-3 fatty acids, and consuming the healthy fats found in salmon and other fatty fish will help you grow shiny, strong nails.
Finally, a magnesium deficiency can lead to vertical ridges in your nails, so it is important to ensure you are meeting your daily magnesium requirements. Whole grains, nuts, and seeds are good sources of magnesium.
In summary, a well-balanced diet with a variety of vitamins, minerals, and nutrients is the best way to achieve strong, shiny, and healthy nails.
