Calcium is an important nutrient that supports nail and bone health. While there is a widespread belief that calcium supplements can improve nail quality, there is no current evidence supporting this claim. In fact, a randomized, placebo-controlled trial found no significant difference in nail quality between postmenopausal women who took calcium supplements and those who did not. While calcium deficiencies can lead to brittle nails, other factors such as environmental conditions, underlying health issues, and iron deficiencies are more common causes. Proper nail care, nutrition, and hydration are key to maintaining nail health, and while calcium supplements may not directly strengthen nails, ensuring adequate calcium intake can support overall nail integrity and reduce fragility.

What You'll Learn
Calcium deficiency can cause brittle nails
Calcium is an important nutrient that plays a role in several bodily functions, including nerve signalling and heart and muscle functioning. It is the most abundant mineral in the human body, with 99% of it stored in the teeth and bones.
Calcium deficiency, also called hypocalcemia, occurs when calcium levels in the blood are low. While calcium deficiency is not dangerous in and of itself, if left untreated for a long period, it can become life-threatening. Deficiency symptoms can be subtle and may overlap with other deficiencies, making them difficult to pinpoint. Some people with calcium deficiencies may experience dry, brittle nails that break easily. Nails can become weak and grow more slowly than usual. However, it is important to note that nutritional deficiencies are usually not the cause of brittle nails. Frequent wetting and drying of the nails is a more common cause of nail brittleness. Additionally, iron deficiencies are more likely to cause brittle nails than calcium deficiencies.
While there is a widespread belief that dietary calcium intake improves nail quality, there is limited scientific evidence to support this claim. 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 nail quality. Among those who did note a change, more women in both groups reported improvement than deterioration, with no significant differences in scores between the two groups.
If you suspect you have a calcium deficiency, it is important to consult a healthcare professional for proper diagnosis and treatment.

Calcium supplements may not strengthen nails
There is a widespread belief among the general public that dietary calcium intake improves the quality of fingernails and toenails. People taking calcium supplements sometimes report that their nails are less brittle, smoother, or that they grow faster. This presumption may have arisen because nails do contain calcium, albeit at a much lower concentration (0.03%) than the skeleton (20-25%).
However, there is currently no evidence to support an association between calcium deficits and brittle nails or increased nail strength with calcium supplementation. A randomized, placebo-controlled trial found no support for the idea that dietary calcium intake alters nail quality in healthy postmenopausal women. 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 scores between the two groups.
It is important to note that nail problems can be a symptom of calcium deficiencies, so they should be monitored. People with severe calcium deficiencies may first experience symptoms that affect their nails, such as weakness, brittleness, and slower nail growth. However, nearly all nutritional deficiencies can slow nail growth, so it cannot be assumed that calcium deficiency is the cause of brittle nails. Iron deficiencies, for example, are more likely to cause brittle nails than calcium deficiencies.
To strengthen nails, it is recommended to practice proper nutrition, drink plenty of water, and avoid certain nail products. Ensuring adequate calcium intake can help maintain nail integrity and reduce fragility, but this does not necessarily require taking supplements, as calcium can be obtained through a balanced diet.

Nutritional deficiencies can slow nail growth
While calcium is important for nail health, taking supplements will not strengthen your nails. Calcium deficiencies can cause dry and brittle nails, but they do not necessarily slow nail growth. In fact, there is no evidence to support the idea that calcium intake affects nail growth at all.
However, it is true that nutritional deficiencies can slow nail growth. A 2010 paper found that nearly all nutritional deficiencies can have this effect. For example, a deficiency in vitamin C can cause brittle nails and slowed nail growth. This is because vitamin C is essential for the production of collagen, which is a protein that gives shape and strength to many tissues, including nails. Zinc is another important nutrient for nail growth, as it is required for the growth and division of cells, which nails are made up of. A lack of zinc can cause degeneration of the nail plate, leading to white spots on the nails.
Iron deficiencies can also affect nail health, causing vertical ridges, concave nails, or "spooned" nails. Magnesium deficiencies may also lead to vertical ridges in the nails. In children, severe protein malnutrition can cause soft and thin nails, while prolonged starvation can result in a 40-50% reduction in body weight and fissured nails.
Biotin, also known as vitamin B7, is another important nutrient for nail growth. It promotes healthy cell growth and aids in the metabolism of protein-building amino acids. A 1993 study found that 2.5 mg of biotin per day for six weeks to seven months improved symptoms of brittle nails in 63% of participants.

Calcium-rich foods for nail health
Calcium is an important nutrient that supports nail and bone health. While calcium supplements are not known to strengthen nails, calcium deficiencies may lead to dry and brittle nails.
Eggs
Eggs are a good source of vitamin D, which helps regulate calcium levels in the body. This, in turn, promotes nail and bone growth. Egg yolks also contain biotin and healthy fats, which are beneficial for nail health.
Meat
Meat, especially lean meats like chicken and turkey, provide collagen and protein, both crucial for nail health.
Fatty Fish
Consuming fatty fish like salmon provides healthy fats and omega-3s, which contribute to shiny and strong nails.
Dairy
Dairy products are a good source of calcium. Including milk, yogurt, and cheese in your diet can help ensure adequate calcium intake, supporting nail and bone health.
Dark Leafy Greens
While the body absorbs iron better from animal sources, dark leafy greens like spinach are plant-based sources of iron. Adequate iron intake can help prevent vertical ridges, concavity, or "spooned" nails associated with iron deficiency.
While focusing on calcium-rich foods, it is also important to maintain overall nutritional balance. Include a variety of fruits, vegetables, nuts, and seeds in your diet, ensuring adequate intake of vitamins, minerals, and nutrients that support nail health.

Calcium supplements and nail quality studies
Calcium supplements and nail quality have been the subject of several studies, with varying results. While some people believe that calcium supplements improve nail quality, the scientific evidence is inconclusive.
One study, published in the New England Journal of Medicine, assessed changes in nail quality in 683 healthy postmenopausal women taking part in a randomized, placebo-controlled trial of calcium supplementation. The women were asked to score the changes in their nail quality, including texture and brittleness, after taking the supplement for 12 months. The majority of women in both the calcium and placebo groups noted no change in their nail quality. Among those who did experience a change, more women in both groups reported improvement than deterioration. However, there were no significant differences in the scores between the two groups, indicating that calcium intake may not alter self-reported nail quality.
Another study, a randomized, placebo-controlled trial, found no support for the idea that dietary calcium intake alters nail quality in healthy postmenopausal women. This study suggested that nail quality is related to the arrangement of cellular and protein components rather than calcium content.
While calcium deficiencies can cause nail problems, such as brittle nails, it is important to note that nutritional deficiencies are usually not the primary cause of brittle nails. Other factors, such as frequent wetting and drying of the nails, are more common causes of nail brittleness. Additionally, iron deficiencies are more likely to cause brittle nails than calcium deficiencies.
Overall, while some individuals taking calcium supplements may anecdotally report improvements in their nail quality, the existing studies do not provide strong evidence to support a direct link between calcium intake and improved nail health. Further research is needed to fully understand the relationship between calcium supplementation and nail quality.
