What deficiency causes itchy hands?

Itchy hands are a common problem that many people face. There are several reasons why your hands may itch, including dry skin, allergies, or skin conditions like eczema. However, did you know that a deficiency in a certain vitamin can also cause itchy hands? In this blog post, we’ll explore the relationship between itchy hands and vitamin deficiency.

The Link Between Itchy Hands and Vitamin Deficiency

One of the main vitamins that can cause itchy hands is vitamin D. This essential nutrient is responsible for helping the body absorb calcium and maintain bone health, but it also plays a crucial role in the health of our skin. In fact, vitamin D is created through skin exposure to the sun and cholesterol in the skin. That’s why, during summer months, people with low vitamin D levels are usually advised to spend time in sun, but with proper precautions to avoid skin damage. Conversely, in the winter months when there is less sun exposure, people are more likely to experience dry, itchy skin and such skin troubles are often attributed to the cold weather.

Studies show that individuals who have a vitamin D deficiency may experience dehydrated skin, patches of discoloured skin, and itchy, dry skin on their hands. The absence of this vitamin can cause a condition known as Dermatitis, which causes the skin to become dry and itchy, and it aggravates already existing skin conditions such as eczema, psoriasis, and rosacea.

Symptoms of Vitamin D Deficiency

It is necessary to be cautious with any form of skin disease and to get appropriate treatment early. Following are some other symptoms that indicate one may have a vitamin D deficiency:

  • Muscle weakness and chronic fatigue
  • Bone fractures, osteoporosis, and osteopenia
  • Depression and mood swings
  • Difficulty thinking clearly
  • Elevated blood pressure
  • Weakened immune system and sicknesses such as flu

How to Treat Vitamin D Deficiency and Itchy Hands

If you suspect you have a vitamin D deficiency, have a blood test to check your levels. Ensure you speak to a healthcare practitioner regarding the right dosage, since over-supplementation may cause other health issues such as hypercalcemia. Even a healthy meal diet should include vitamin D containing food and sufficient sun exposure. You can also address the symptoms of itchy hands through several home remedies, including:

  • Moisturizing with a gentle, fragrance-free lotion or cream that is suitable for your skin type. Avoid using harsh soaps or detergents that can dry out your skin further.
  • Lukewarm baths with oatmeal soothes itchy skin – it is proven to reduce inflammation and irritation
  • Avoiding prolonged exposure to hot water – it may worsen itchy and dry skin
  • Minimizing alcohol intake – it is another trigger that causes itchy skin
  • Wearing protective gloves to avoid skin exposure to detergents, very hot or very cold temperatures, plants, etc.
  • Using a humidifier to add moisture to the air


Itchy hands can be a frustrating and uncomfortable condition to deal with, but often, it is possible to address the issue with relatively simple solutions. If you are experiencing itchy hands, it may be worth looking at your vitamin D levels and ensuring that you are getting the right amount daily. Engage in outdoor activities as much as possible, but ensure proper precautions to protect the skin. Maintaining adequate levels of vitamin D in your body can help support healthy skin and avoid skin-related issues that make an already existing problem even worse.


Why are my hands itchy but no rash?

Itching sensations are a common problem that affects people of all ages. If your hands are itchy but there is no evidence of a rash, the list of possible causes is not limited to a few. While having an itchy skin is not life-threatening, it can make you uncomfortable, disrupt your sleep, affect your quality of life, and in some cases, indicate a health problem.

The causes of skin itching, or pruritis, are usually harmless. They are often temporary issues such as insect bites, dry skin, or exposure to chemicals, which can dry and irritate the skin. In addition, stress, heat, and sweating can cause the hands to itch intermittently and temporarily. Frequent hand washing and use of soaps and hand sanitizers can also cause the hands to itch as these products strip the natural oils from the skin, leaving it dry and dehydrated.

If you have itchy hands, another possible cause could be nerve damage. Some diseases, such as diabetes, can damage the nerves leading to the hands, causing them to itch without visible signs of a rash. Similarly, liver or kidney issues can cause severe itching as these organs play a vital role in filtering the blood and eliminating toxins. When they malfunction, waste substances can accumulate in the body and cause the skin to itch.

Hormonal imbalances, including thyroid problems, can also lead to itching sensations without a rash. The thyroid gland plays a crucial role in regulating metabolic activity, and when it malfunctions, it can lead to changes in the skin, such as dryness, flakiness, and itching.

Itchy hands without a rash have a wide range of causes, both temporary and chronic. Luckily, most of them are not severe nor life-threatening. If the itching persists or is severe, it is advisable to seek medical attention. During a physical exam, a doctor may examine the skin and ask questions to determine the cause of the itching. Depending on the cause, a doctor may recommend certain treatments, such as antihistamines, moisturizing creams, or prescription medication, to help relieve the itch.

Can low magnesium cause itching?

Magnesium is an essential mineral required by the body for various functions, including muscle and nerve function, protein synthesis, blood glucose control, and maintaining normal heart rate and blood pressure. Low levels of magnesium in the body can cause several health problems, including weakness, muscle cramps, and irregular heartbeat.

However, the link between low magnesium levels and itching is not straightforward. While it’s true that a magnesium deficiency can cause some skin-related symptoms, such as dry skin or skin rashes, there isn’t enough scientific evidence to support the claim that magnesium deficiency causes itching specifically.

There are several possible causes of itching, including dry skin, allergies, infections, and medication side effects, among others. It is essential to understand that while magnesium is an important mineral for maintaining healthy skin, it is not a cure for itching. However, magnesium can help reduce inflammation in the body caused by certain conditions, such as eczema, that lead to dry and itchy skin.

Low magnesium levels alone may not cause itching, but it can lead to several other health problems. Itching can have various underlying causes, and while magnesium is vital for maintaining healthy skin, it is not a definitive solution for itching. If you are experiencing persistent and severe itching, it’s essential to consult a healthcare professional to determine the underlying cause and appropriate course of treatment.

Can low B12 cause itchy hands?

Vitamin B12 is an essential nutrient for the proper functioning of the nervous system and the production of red blood cells. It is found mainly in animal-based foods such as meat, fish, and dairy products. However, some people may experience a deficiency of this vitamin due to various reasons, including poor absorption or inadequate intake. One of the symptoms of a B12 deficiency that is less commonly known is itchy skin.

Itchy skin is a common problem that can be associated with a number of factors, such as allergies, insect bites, dry skin, and infections. However, it may also be a sign of nutrient deficiencies, including vitamin B12. When the body lacks sufficient amounts of this vitamin, it can cause a range of skin problems from dry, scaly skin to itchiness and rashes.

One possible explanation for this is that B12 plays a role in the development and maintenance of healthy skin cells. It also helps regulate the production of oil in the skin, which can help prevent dryness and itching. A deficiency of B12 can disrupt these processes, leading to skin irritation and inflammation.

Another explanation for the link between B12 deficiency and itchy skin is that B12 is involved in the production of histamine, a chemical that is released by the immune system in response to certain triggers, such as allergens or irritants. Histamine can cause a range of symptoms, including itching, swelling, and redness. When there is not enough B12 in the body, histamine levels can become imbalanced, leading to skin problems.

Although more research is needed to establish a clear link between B12 deficiency and itchy skin, there is some evidence to suggest that getting enough B12 can help improve skin health. In addition to reducing itchiness, B12 can also help reduce the risk of other skin problems, such as acne, eczema, and psoriasis.

If you are experiencing chronically itchy skin, getting your level of B12 tested can be helpful. This testing will help determine whether a deficiency of B12 is at the root of your skin sensitivities and itchiness. If a B12 deficiency is diagnosed, your doctor may recommend increasing your intake of B12-rich foods or taking supplements to help correct the deficiency and relieve your skin symptoms.

Can magnesium make your hands itch?

Magnesium is an essential mineral that plays an important role in many body functions, including muscle and nerve function, energy production, and bone development. Generally, magnesium supplements are safe and well-tolerated, but there may be some side effects to taking too much of it.

One such side effect is skin irritation, which may lead to itching, especially on the hands. This may be due to an allergic reaction to the magnesium supplement or an increase in magnesium levels in the body. If you experience skin irritation or itching while taking a magnesium supplement, it is essential to discontinue use and seek medical advice.

It is also worth noting that an overdose of magnesium can lead to a host of other symptoms, including confusion, dizziness, muscle weakness, irregular heartbeat, and even breathing problems. However, an overdose of magnesium is relatively rare, especially if you are taking it as a dietary supplement.

While magnesium is an essential mineral that can provide many health benefits, it is crucial to be aware of the potential side effects that may come with taking magnesium supplements. Skin irritation, including itching on the hands, is one such side effect, and if you experience this symptom, it is vital to seek medical advice.
