Calcium is an important nutrient that plays a role in several bodily functions, including supporting nail and bone health. Calcium-deprived nails tend to grow slowly and become brittle. However, there is no evidence that consuming calcium supplements or calcium-rich foods will improve nail growth. While calcium is necessary for healthy nails, it is unclear whether increasing calcium intake will have any effect. Several other factors, such as frequent wetting and drying of nails, are more likely to cause brittle nails.

Calcium deficiency may cause slow nail growth, but it is not the only cause
Calcium is an important nutrient that plays a role in several bodily functions, including supporting nail and bone health. It is the most abundant mineral in the human body, with 1% of the body's calcium supporting bodily functions like nerve signalling and muscle functioning, and the remaining 99% stored in the teeth and bones.
While calcium is essential for nail health, taking calcium supplements may not directly strengthen your nails. A study published in the New England Journal of Medicine found no significant difference in self-reported nail quality between healthy postmenopausal women taking calcium supplements and those taking a placebo. The study assessed subjective changes in nail quality, including texture and brittleness, over a 12-month period.
Several other factors can influence nail growth and health. Vitamin deficiencies can cause changes in nail texture, strength, and appearance. B vitamins, in particular, are essential for optimal nail health, and a deficiency can cause pigment changes or ridges in the nails. Vitamin A, a form of retinol, is also beneficial for nail health, as it hydrates and regenerates growth in thin and brittle nails. Omega-3 fatty acids are important for lubricating and moisturising the nail beds, promoting healthy growth and preventing dryness and brittleness.
Overall, while calcium deficiency may contribute to slow nail growth, it is important to consider other potential causes, such as nutritional deficiencies, frequent wetting and drying of the nails, and underlying health concerns.

Calcium-rich foods may help nail growth, but supplements may not
Calcium is an important nutrient that supports nail and bone health. Calcium-deprived nails tend to grow very slowly and become weak and brittle. However, almost all nutrient deficiencies can slow down nail growth, so calcium deficiency is not necessarily the cause of these issues.
There is a widespread belief that dietary calcium intake improves nail quality. People taking calcium supplements often claim that their nails grow faster and are less brittle or smoother. However, there is no scientific evidence to support these claims. A study published in the New England Journal of Medicine assessed subjective changes in nail quality in 683 healthy postmenopausal women taking part in a randomized, placebo-controlled trial of calcium supplementation. The majority of women in both the calcium and placebo groups noted no change in their nails. Among those who did note a change, more women in both groups reported improvement than deterioration, with no significant differences in the scores between the two groups.
While oral ingestion of calcium may not have any positive effects on nails, calcium deficiency can indeed lead to nail problems. People with severe calcium deficiencies may first notice symptoms affecting their nails. In addition to slow nail growth, calcium deficiency can cause nails to become dry, brittle, and weak. Therefore, ensuring adequate calcium intake through diet or supplements may help prevent or improve nail problems caused by calcium deficiency.
Calcium-rich foods that can help improve nail health include dairy products such as milk, yogurt, and cheese. If dairy is not an option, one can increase their calcium intake through fortified juices and plant milks, as well as tofu, kale, and bok choy. In addition to calcium, other nutrients essential for nail health include biotin, folate, B vitamins, vitamin A, omega-3s, and magnesium. These nutrients can be obtained from a variety of foods, including liver, egg yolk, salmon, avocado, sweet potato, nuts, seeds, leafy greens, citrus fruits, beans, and lentils.

Calcium is important for nail health, but nails don't need much
Calcium is an important nutrient that plays a role in several bodily functions, including nerve signalling, heart and muscle functioning, and blood clotting. While calcium is indeed beneficial for nail health, it is important to note that nails do not require a significant amount of calcium to be healthy.
The human body is very efficient at regulating calcium levels, and it only takes 1% of the body's calcium supply to perform all the essential functions that calcium supports. The remaining 99% of the body's calcium is stored in the bones and teeth, where it is kept in reserve and released as needed. This means that even if an individual is not consuming enough calcium through their diet, the body can draw from these reserves to maintain healthy calcium levels in the places that need it most.
While calcium is important for overall health, including nail health, there is limited evidence to suggest that increasing calcium intake through supplements or diet will directly lead to stronger or healthier nails. In fact, a study published in the New England Journal of Medicine found no significant difference in nail quality between a group of healthy postmenopausal women who took calcium supplements and a placebo group. The majority of women in both groups reported no change in their nails, and among those who did note a change, there was no significant difference in the proportion of women who experienced improvement or deterioration.
It is worth noting that calcium deficiencies can sometimes manifest as nail problems, such as brittle or slow-growing nails. However, these issues are more commonly caused by frequent wetting and drying of the nails or deficiencies in other nutrients, such as iron or B vitamins. Additionally, nail problems can be a symptom of other underlying health concerns, so it is always a good idea to consult a doctor if you are experiencing persistent nail issues.
In conclusion, while calcium is indeed important for nail health, it is not necessary to focus solely on increasing calcium intake to promote healthier nails. A well-rounded diet that includes a variety of nutrients, such as omega-3s, zinc, and B vitamins, is more likely to result in strong and healthy nails.

Other nutrients like biotin, folate, and B vitamins also support nail growth
While calcium is essential for keeping the body strong and functional, and deficiencies can cause nails to grow slowly, almost all nutrient deficiencies can have this effect. Therefore, calcium deficiency is not necessarily the cause of slow nail growth.
Biotin, a B-complex vitamin, also known as vitamin B7, coenzyme R, and vitamin H, is often marketed as a supplement for hair and nail growth. However, there is little scientific evidence to support these claims. Nevertheless, biotin deficiency can cause brittle nails and hair loss, so taking biotin supplements may help if you have a deficiency. Studies show that taking 2.5 mg of biotin daily may improve nail firmness, hardness, and thickness. Biotin-rich foods include organ meats, egg yolk, dairy products, yeast, salmon, avocado, sweet potato, nuts, seeds, and cauliflower.
Folate, or vitamin B9, is another important nutrient for nail growth and health. It contributes to red blood cell formation and the development of new cells. A folate deficiency can cause nail discolouration and make nails rigid and brittle. Adults require 400 mcg of folate per day, while pregnant women have an increased need. Folate can be found in dark green vegetables, citrus fruits, beans, peas, lentils, nuts, seeds, and avocados.
Vitamin B12 is also necessary for nail health, as it plays a role in iron absorption and red blood cell development. A deficiency can cause nail discolouration, and in some cases, bluish-black pigments with wavy longitudinal dark streaks and brownish pigmentation. Adults require 2.4 mcg of vitamin B12 per day, although pregnant women may need more. Vitamin B12 is found primarily in animal foods such as meat, poultry, fish, eggs, and dairy, although it can be fortified into other foods and beverages.

Vitamin deficiencies often show up as changes in nail texture, strength, and appearance
While calcium is an important nutrient for several bodily functions, including supporting nail and bone health, there is no evidence that consuming calcium supplements or food sources rich in calcium will help nails grow. Nails do contain calcium, but at a much lower concentration of 0.03%.
A deficiency in B vitamins will cause pigment changes or ridges in your nails. To increase your B vitamin intake, eat green leafy vegetables, citrus fruits, beans, lentils, avocado, nuts, and seeds. Animal products such as meat, poultry, fish, dairy, and eggs are a good source of B-12.
If you see white spots on your nails, you may need more zinc in your diet. Zinc is necessary for cell growth, which promotes healthy nail growth. Animal products like poultry, beef, fish, and eggs are great sources of zinc. Alternatively, you can get your daily zinc intake from chickpeas, black beans, almonds, and cashews.
If your nails are brittle and weak, you may need more calcium in your diet. Dairy products like milk, yogurt, and cheese are the best sources of calcium. If dairy is not an option, you can increase your calcium intake from fortified juices and plant milks, as well as foods like tofu, kale, and bok choy.
