White spots on your nails, also known as leukonychia, are often thought to be a sign of calcium deficiency. However, this is a common misconception. While calcium deficiency can cause more significant changes to your nails, such as brittleness or alterations in shape, white spots are usually caused by minor trauma or damage to the nail bed.

Calcium spots on nails are not indicative of calcium deficiency
White spots on nails, known as leukonychia, are usually not a sign of calcium deficiency. Instead, they are often the result of minor trauma or damage to the nail matrix, the tissue under the nail responsible for cell production that forms the nail plate. Nails grow slowly, so this damage can take time to appear and even longer to fade.
While white spots on nails can be caused by a deficiency in certain minerals and/or vitamins, these tend to be rare. Dr Rekha Tailor explains that the deficiencies most commonly linked to white spots are zinc and calcium. However, severe calcium deficiency tends to manifest differently in nails, often leading to more significant changes like brittleness or alterations in nail shape.
In some cases, white spots on nails can indicate allergic reactions to nail polish, hardeners, or other products used in nail care. Less commonly, they can be a sign of fungal infections, which usually come with additional symptoms like nail thickening or discolouration.
Frequent manicures and pedicures can also damage the nail beds, leading to white spots.

White spots on nails can be caused by a fungal infection
White spots on nails are not caused by a calcium deficiency. Instead, they are usually the result of an earlier injury to the nail matrix, which is called leukonychia. However, they can also be caused by a fungal infection.
Nail fungus is a fungal infection of the fingernails or toenails. It often starts as a yellow or white spot under the tip of the nail. If untreated, the infection can spread deeper into the nail, causing it to thicken, crumble, or become discoloured. Nail fungus can lead to pain and, in rare cases, it can be a sign of severe malnutrition in children or people with low blood protein.
The main cause of nail fungus is the dermatophyte, Trichophyton mentagrophytes. This fungus develops on the top layers of the nail and eventually spreads across the entire nail plate. As the fungus spreads, the nails may dry out and the surface of the nails may flake and crumble. The fungus feeds on the nail protein, keratin, to obtain its nutrients, which further weakens the nail plate and makes it distorted.
Nail fungus is spread like any other fungus – through unsanitary tools and files, but also in places like locker rooms and other places where people go barefoot.

White spots on nails can be caused by an allergy to a particular food item or nail paint
White spots on nails, known as "punctate leukonychia", are usually not a problem and will go away in time. They typically result from injury to the nail, such as biting your nails or jamming your fingertips, which can cause air to get trapped within the nail, giving it a white appearance. However, in some cases, they may indicate other health conditions, such as vitamin deficiencies, fungal infections, or more serious illnesses like diabetes, liver disease, or kidney disease.
While it is uncommon, white spots on nails can occasionally be caused by an allergy to a particular food item or nail paint. If you suspect that an allergy is the cause of your white spots, it is important to consult a healthcare professional, who can help identify the allergen and recommend appropriate treatment. They may recommend an elimination diet, where certain foods are temporarily removed from your diet, or suggest that you switch to hypoallergenic nail products.
It is important to be mindful of any other symptoms you may be experiencing alongside the white spots, as this can help your healthcare provider make an accurate diagnosis. For example, if you are also experiencing fatigue, increased thirst, or weight loss, it could indicate an underlying condition such as diabetes.
If you have frequent or widespread leukonychia or lines running through your nails, it is recommended that you speak with a healthcare provider. They can help determine the underlying cause and provide appropriate treatment or management strategies.

They are usually caused by an earlier injury to the nail matrix or bed, which can take time to appear as nails grow slowly. In rare cases, white spots can point towards a deficiency, but this is not necessarily related to calcium and could be due to a lack of any mineral, such as zinc or biotin.
