What You'll Learn
Zinc deficiency
White spots on the nails can be caused by a zinc deficiency. Zinc is a mineral that is required to produce testosterone. A zinc deficiency can lead to reduced circulating testosterone, which could lead to sexual immaturity, hypogonadism, and delayed puberty. It can also cause skin changes that look like eczema, hair loss, more frequent infections, wounds that take a long time to heal, and diarrhoea. It may also manifest as acne, xerosis (dry, scaling skin), seborrheic dermatitis, or alopecia (thin and sparse hair).
Zinc supplements are used to treat a zinc deficiency and cause a rapid improvement in skin symptoms.

Calcium deficiency
White spots on your nails can be caused by a calcium deficiency. While white spots on nails are often the result of a nail injury called leukonychia, they can also be caused by allergies, fungal infections, mineral deficiencies, or heavy metal poisoning.
Calcium is an essential mineral for maintaining healthy bones and teeth. It is also necessary for proper nerve and muscle function, including the heart. A calcium deficiency can lead to weak and brittle nails, as well as other symptoms such as muscle cramps, numbness or tingling in the hands and feet, and seizures.
The recommended daily intake of calcium for adults is 1000-1200 mg. Good sources of calcium include dairy products such as milk, yoghurt, and cheese, as well as dark leafy greens like spinach and kale. Calcium can also be found in tofu, broccoli, and calcium-fortified foods like orange juice and breakfast cereals.
If you suspect you have a calcium deficiency, it is important to consult a doctor or healthcare professional. They can perform a blood test to check your calcium levels and recommend appropriate treatment or dietary changes.
In addition to dietary sources, calcium supplements are also available to help meet your daily requirements. However, it is always best to prioritise getting calcium from natural food sources whenever possible.

Iron deficiency
White spots on the nails can be caused by a deficiency in certain vitamins or minerals. While zinc and calcium deficiencies are the most common causes, iron deficiency is also a possible cause.
Iron is an essential mineral that plays a vital role in transporting oxygen throughout the body. It is a key component of haemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body. Iron is also important for energy production, immune function, and cognitive development.
The recommended daily intake of iron varies depending on age, gender, and health status. For adult men and postmenopausal women, the recommended daily intake is 8 mg, while premenopausal women need 18 mg due to iron loss during menstruation. Pregnant women require even more iron, with a recommended daily intake of 27 mg to support the increased blood volume and nutrient demands of the growing fetus.
There are two types of dietary iron: heme and non-heme. Heme iron is found in animal-based foods such as red meat, poultry, and seafood, and is more easily absorbed by the body. Non-heme iron is present in plant-based sources, including beans, lentils, spinach, and fortified cereals. While non-heme iron is not as readily absorbed as heme iron, pairing it with vitamin C-rich foods can enhance absorption.

It is important to note that white spots on the nails can also be caused by other factors, such as trauma-related leukonychia, which will usually grow out with the nail plate over time.

If you are concerned about white spots on your nails, it is recommended to consult a doctor or healthcare provider for proper diagnosis and treatment.

Albumin protein deficiency
White spots on the nails can be caused by a deficiency in albumin protein. Albumin is a protein made by the liver and is important for maintaining fluid balance in the body. It also helps transport other molecules, such as hormones, vitamins and minerals, through the blood.
A deficiency in albumin can be caused by a variety of factors, including liver disease, malnutrition, and inflammatory bowel disease. In some cases, it may also be a sign of a more serious underlying medical condition, such as kidney disease or cancer.
The symptoms of albumin deficiency can include swelling in the legs and abdomen, fatigue, and an increased risk of infection. In some cases, people with albumin deficiency may also experience nausea, vomiting, and diarrhoea.
Treatment for albumin deficiency typically involves addressing the underlying cause. For example, if the deficiency is due to liver disease, treatment may involve medications or lifestyle changes to improve liver function. In cases of malnutrition, increasing protein intake and taking albumin supplements may be recommended.
It is important to note that white spots on the nails can also be caused by other factors, such as nail injuries, allergies, fungal infections, or heavy metal poisoning. Therefore, it is always advisable to consult a doctor to determine the underlying cause and receive appropriate treatment.
