Calcium is an important nutrient that plays a role in several bodily functions, including blood clotting, blood vessel contraction and dilation, nerve signaling, heart and muscle functioning, and organ hormone secretion. It is the most abundant mineral in the human body, and while most of it is stored in the bones and teeth, a small amount is found in the nails. There is a widespread belief that dietary calcium intake improves nail quality, and some people with calcium deficiencies experience brittle nails. However, research suggests that nail health is related to the arrangement of its cellular and protein components rather than calcium content.
| Characteristics | Values |
|---|---|
| Calcium in finger nails | Nails contain calcium, albeit at a much lower concentration (0.03%) than the skeleton (20-25%) |
| Calcium deficiency | Can lead to hypocalcemia, a calcium disorder that can weaken bones, lead to osteoporosis and bone fractures, and cause nerve and muscle problems. |
| Calcium supplements | Some people taking calcium supplements have reported that their nails are less brittle, smoother, or that they grow faster. |
| Calcium and nail health | Research does not support the notion that calcium supplements help build strong nails. |
| Calcium deficiency and nails | Weakened, brittle, or slow-growing nails tend not to be the result of a calcium deficiency. |
| Calcium and diet | Calcium is an important nutrient that plays a role in supporting nail and bone health. |
| Calcium and nail problems | Nail problems can be a symptom of calcium deficiency, but the underlying cause may be a different nutritional deficiency or health concern. |

Nail problems can be a symptom of calcium deficiency, but it is important to note that they could also be caused by other nutritional deficiencies or health concerns. Weak, brittle, or slow-growing nails are more likely to be caused by frequently wetting and drying the nails than by a calcium deficiency. However, severe calcium deficiencies may first affect the nails, causing them to become weak, brittle, and slow-growing.
There is a widespread belief that dietary calcium intake improves nail quality. People taking calcium supplements sometimes report that their nails are less brittle, smoother, and grow faster. This could be because nails contain calcium, although at a much lower concentration (0.03%) than the skeleton (20-25%). However, a study of 683 healthy postmenopausal women taking calcium supplements found no significant difference in reported nail quality between the calcium and placebo groups.
If you are concerned about calcium deficiency or want to improve your nail health, it is recommended to focus on getting calcium through your diet. Calcium-rich foods include dairy, nuts, leafy greens, and fish. Calcium supplements are also an option, but it may require some trial and error to find the right one for you. Calcium is best absorbed when taken in amounts of 500-600mg or less, and it is preferable to take it with a meal.

Calcium deficiencies can cause brittle nails, but this is not always the case
Calcium is the most abundant mineral in the human body. It helps our blood clot, our blood vessels contract and dilate, our nerves transmit signals, our muscles flex and relax, and our organs secrete hormones.
Nails contain calcium, albeit at a much lower concentration (0.03%) than the skeleton (20-25%). Calcium is important for nail and bone health, and a deficiency can lead to brittle nails. However, nail problems can be indicative of other nutritional deficiencies or health concerns. For instance, white bands on nails are associated with severe malnutrition or low blood protein, but are unrelated to calcium.
There is a widespread belief that dietary calcium intake improves nail quality, and people taking calcium supplements often report that their nails are less brittle. However, research does not support the idea that calcium intake alters nail quality. A 2000 study published in the New England Journal of Medicine found no significant difference in self-reported nail quality between a group of healthy postmenopausal women taking calcium supplements and a placebo group. Similarly, a 2010 paper concluded that nearly all nutritional deficiencies can slow nail growth, not just a lack of calcium.
While calcium deficiencies can cause brittle nails, it is not always the case. Other factors, such as frequently wetting and drying the nails, can also contribute to nail problems.

Calcium is important for nail health, but it is not the only nutrient that matters
Calcium is an important mineral 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 such as nerve signalling, heart health, and muscle functioning. The other 99% is stored in the teeth and bones.
Nail problems such as brittle, thin, or weak nails can be a symptom of calcium deficiency. However, it is important to note that almost all nutrient deficiencies can slow down nail growth, so it is not always a calcium deficiency that is the culprit. Additionally, nail problems could be a result of frequently wetting and drying the nails, which is the most common cause of nail issues.
While calcium is important for nail health, it is not the only nutrient that matters. Nails are made mainly of the hardened protein keratin, so consuming foods that create beautiful hair can also help nails stay strong. For example, protein is necessary for nail growth and strength, zinc keeps nails from weakening, and iron keeps nails from distorting into spoon shapes. Consuming a well-balanced diet rich in nutrient-dense foods like colourful produce, whole grains, lean proteins, and low-fat dairy products is the best way to support nail health.
Research has also shown that nail health could be an indicator of general bone health. A 2018 review found that poor nail health could be an indirect way of assessing the risk of bone conditions. Additionally, a 2008 study found a positive correlation between fingernail calcium concentration and lumbar bone mineral density in a group of women in their sixties. This suggests that nail mineral content may be used as an indicator of bone mineral metabolism.

Calcium deficiencies can be hard to detect as they may cause no immediate symptoms
Calcium is the most abundant mineral in the human body and plays a role in several bodily functions, including supporting nail and bone health. However, despite its importance, calcium deficiencies can be hard to detect as they may cause no immediate symptoms.
When the body does not absorb enough calcium, it uses its stored supply in the bones. This can lead to a gradual weakening of the bones over time, increasing the risk of fractures and other injuries. While this depletion can be detected by routine blood tests, it often goes unnoticed until the bones break or are tested.
Some people with calcium deficiencies may experience dry, brittle nails, but this is not always the case. Other nail problems, such as slow nail growth, can also be a sign of calcium deficiency. However, it is important to note that nail issues can also be caused by other nutritional deficiencies or health concerns.
In addition to nail problems, calcium deficiencies can cause various symptoms, including muscle aches, fatigue, constipation, insomnia, and difficulty concentrating. More severe deficiencies can lead to serious health complications, such as osteoporosis, dental changes, cataracts, alterations in the brain, and an increased risk of heart disease, hypertension, stroke, and certain cancers.
To prevent or treat calcium deficiency, it is important to ensure adequate calcium intake through diet or supplements. Doctors may recommend consuming more calcium-rich foods or taking calcium and vitamin D supplements to boost calcium levels and prevent potential health complications.

Calcium-deprived nails tend to grow slowly, but other deficiencies can also slow nail growth
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 such as nerve signalling and heart or muscle functioning. The other 99% is stored in the teeth and bones.
Nail problems can be a symptom of calcium deficiency, and people taking calcium supplements often report improvements in their nail quality. However, it is important to note that weakened, brittle, or slow-growing nails are usually not the result of a calcium deficiency. While calcium-deprived nails tend to grow slowly, almost all nutrient deficiencies can slow down nail growth, so it is essential to consider other possible deficiencies or health concerns.
The body can live with a calcium deficiency for a long time without realising it, as it draws from the reserve in the bones to get the calcium it needs. Over time, this can weaken the bones and increase the risk of fractures and other injuries. People with severe calcium deficiencies may first notice symptoms affecting their nails, such as weakness, brittleness, and slow growth.
While the link between calcium intake and nail health is not conclusive, some research suggests that nail health could be an indicator of general bone health. For example, a study found a significant positive correlation between fingernail calcium concentration and lumbar bone mineral density in a group of women in their sixties.
To maintain strong and healthy nails, it is essential to eat a well-balanced diet rich in nutrient-dense foods, including colourful produce, whole grains, lean proteins, and low-fat dairy products.
