Vitamin B12 is a water-soluble vitamin that is routinely required in our daily diet. It is involved in the synthesis of DNA, red blood cells, and energy production. A deficiency in vitamin B12 can lead to various health issues, including nail problems. While B12 is important for nail health, there is no evidence that it directly increases nail growth beyond what is considered normal for an individual. However, correcting a B12 deficiency through supplementation or dietary adjustments may improve overall nail health, making nails stronger and less prone to breakage.

What You'll Learn
B12 deficiency can cause nail discolouration
Vitamin B12 is essential for nail health and plays a crucial role in cell division and growth, including the cells responsible for nail development. A lack of B12 can lead to changes in nail structure, making nails more susceptible to splitting, cracking, and peeling. It can also cause nails to become dry, brittle, and unnaturally dark, with some sources stating that it can result in rounded and curved nails.
Nails can act as a window to overall health, and discolouration can indicate a lack of oxygen reaching the nails. B12 deficiency is easily treatable with supplemental support, and improvements in nail pigmentation can be expected over several months. However, poor absorption is a common issue, and oral supplements may not be as effective as liquid sprays absorbed in the mouth, bypassing the digestive tract.
It is important to note that while B12 is crucial for nail health, it is just one of many factors influencing nail growth and texture. Genetics, age, hormonal factors, and overall health also play significant roles in nail growth and strength.
Vegan and vegetarian diets are most at risk of B12 deficiency due to the lack of plant-based sources. Animal sources of B12 include meat, poultry, fish, eggs, dairy, and beef liver, while fortified cereals and breads are also options for those not consuming animal products.

B12 helps nail growth by aiding cell division
Vitamin B12 is an essential nutrient that plays a crucial role in maintaining overall health and wellness. While it is known for its benefits for skin, hair, and nails, its impact on nail growth is particularly noteworthy. B12 helps nail growth by aiding cell division, a fundamental process in the development of strong and healthy nails.
Nails are primarily composed of a fibrous structural protein called keratin, which gives them their strength and resilience. This keratin is produced by cells, and B12, as an essential nutrient, plays a vital role in cell division and growth. Every cell in the body requires a constant supply of B12, and when it is deficient, it can lead to abnormalities in cell growth and development.
In the context of nail health, a deficiency in vitamin B12 can result in nail deformation, making them rounded and curved. The nails tend to become dry, brittle, and unnaturally dark in colour. These changes in nail structure make them more susceptible to splitting, cracking, and peeling. Therefore, by aiding in cell division and supporting overall cell health, B12 helps promote nail growth and strengthens nails, making them less prone to breakage.
Vitamin B12 is involved in the synthesis of DNA, which is essential for cell growth and repair. It also plays a role in the metabolism of fat and protein, contributing to the overall health of the body, including nails. B12 helps regulate homocysteine levels in the blood, which is important for maintaining heart health. Additionally, adequate levels of B12 have been linked to better bone mineral density, preventing osteoporosis and maintaining strong bones.
To ensure optimal nail health and promote growth, it is essential to include vitamin B12 in your daily diet. B12-rich foods include animal products such as meat, poultry, fish, eggs, and dairy. For those following a vegan or vegetarian diet, B12 supplements or fortified foods are recommended to meet their B12 needs.

B12-rich foods include meat, fish, and dairy
While there is no direct evidence that vitamin B12 directly contributes to nail growth, it is an essential nutrient for overall wellness and healthy nails. Vitamin B12 is required for proper brain function and is involved in several chemical reactions in the body. Nails can act as a window to your overall health, and their appearance can indicate a vitamin B12 deficiency. For example, blue nails could mean that your nails are not getting enough oxygen, which could be due to low vitamin B12 levels.
Vitamin B12 is primarily found in animal products, especially meat and dairy. Organ meats, such as liver and kidneys, are very high in vitamin B12. Other good sources include fish, such as clams, rainbow trout, and tuna. Dairy products like milk, cheese, and eggs are also rich in vitamin B12. For those who follow a vegan diet, fortified foods like breakfast cereals and nutritional yeast are good sources of vitamin B12.
In addition to vitamin B12, several other nutrients are essential for nail health and growth. Nails are primarily made of a fibrous structural protein called keratin, and eating enough protein is crucial for boosting keratin production and creating strong nails. Whole grains, specifically whole wheat, are a good source of magnesium, another essential mineral for nail growth. Vitamin C is also necessary for nail health as it is involved in the production of collagen, which gives shape and strength to nails. While citrus fruits are the best sources of vitamin C, bell peppers, green vegetables, and tomatoes are also excellent sources.
Overall, while vitamin B12 may not directly influence nail growth, it is crucial for overall nail health and can help prevent nail-related issues. A well-rounded diet that includes B12-rich foods like meat, fish, and dairy, along with other essential nutrients, will contribute to strong and healthy nails.

B12 supplements can improve nail health
Vitamin B12 is essential for cell division and growth, including the cells responsible for nail development. A lack of B12 can lead to changes in nail structure, making them more susceptible to splitting, cracking, and peeling. B12 deficiency is a common root cause of nail conditions and is easily treatable with supplemental support. However, B12 requires many steps for absorption, and poor absorption is a common issue. To bypass this issue, a liquid vitamin B12 spray can be absorbed in the mouth.
Vitamin B12 is naturally found in animal products, such as meat, poultry, fish, eggs, and dairy. Vegans and vegetarians are most at risk of becoming deficient because there are no plant foods that are rich sources of B12. However, B12 can be fortified into other foods and beverages. For example, vegans and vegetarians can get B12 from fortified cereals and breads. Organ meats, like beef liver and kidneys, are very high in B12. If you don't like organ meats, clams are another good source of B12.
In addition to B12, other nutrients are important for nail health. Nails are made from a protein called keratin, so including protein-rich foods in your diet can help strengthen your nails and promote growth. Vitamin C is also essential for nail health, as it is necessary for the production of collagen, which gives shape, strength, and integrity to many tissues, including fingernails, hair, and teeth. Deficiency in vitamin C can result in brittle nails and slowed nail growth.

B12 deficiency can cause brittle nails
B12 deficiency can cause nail discolouration, making them appear brown-grey, bluish, or dark. Nails may also become dry, brittle, and weak, and their structure may change, making them more prone to splitting, cracking, and peeling. This is because B12 is involved in the synthesis of DNA, which is necessary for cell growth, development, and repair.
Vitamin B12 is a water-soluble vitamin that is routinely required in our daily diet. It is involved in the synthesis of red blood cells, DNA, methylation, and energy production. Every cell in the body needs a constant supply of B12. Low B12 levels can lead to red blood cell abnormalities, anaemia, and various health issues.
B12 deficiency is a common root cause of nail conditions and is easily treatable with supplemental support. The best treatment for vitamin B12 deficiency is supplementation, and high oral doses of vitamin B12 (1000–2000 mcg) are as effective as vitamin B12 injections to optimise blood levels of B12. However, B12 requires many steps for absorption, and poor absorption is a common issue. A liquid vitamin B12 spray absorbed in the mouth may be a solution to this problem, as it bypasses the digestive tract.
B12 deficiency is associated with hair loss, but there is insufficient evidence to show that taking B12 supplements will help hair grow back. Similarly, while B12 deficiency can cause nail issues, there is no evidence that supplementation will lead to a significant increase in nail growth beyond what is considered normal for an individual.
