There are many possible symptoms of vitamin D deficiency, although it is also possible to have no symptoms at all. Here in this article, Healthwords will walk you through both what Vitamin D does, why it is so important and what the symptoms of vitamin D deficiency are so that you can be on the lookout.
Vitamin D is a fat-soluble vitamin that plays a crucial role in various physiological processes in the body. There are two primary forms of vitamin D: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D2 is derived from plant sources, while vitamin D3 is synthesised in the skin in response to exposure to ultraviolet B (UVB) radiation from the sun and is also found in some animal-based foods.
One of the key roles of vitamin D is to facilitate the absorption of calcium and phosphorus in the intestines. This is essential for maintaining strong and healthy bones and teeth.
Vitamin D is critical for bone health, as it helps regulate calcium levels in the blood and promotes the mineralisation of bone tissue. Deficiency can lead to conditions like rickets in children and osteomalacia in adults.
Vitamin D is involved in the regulation of the immune system. It plays a role in modulating immune responses and may help in reducing the risk of certain autoimmune diseases.
Vitamin D is implicated in cell growth, proliferation, and differentiation. It has been studied for its potential role in preventing certain types of cancers, although the evidence is still being explored.
There is evidence suggesting a link between vitamin D levels and mood regulation. Some studies have explored its potential role in reducing the risk of mood disorders, although more research is needed in this area.
Vitamin D deficiency can manifest through a range of symptoms, affecting various aspects of health. One prominent sign is musculoskeletal issues, including bone pain and muscle weakness.
In children, a deficiency can lead to a condition called rickets, characterised by softened and weakened bones, delayed growth, and skeletal deformities.
In adults, a deficiency may contribute to osteomalacia, where bones become fragile and prone to fractures. Fatigue and generalised weakness are common, as vitamin D plays a crucial role in muscle function. Individuals with low levels of vitamin D may also experience mood changes, including depression and irritability, highlighting the vitamin's role in neurological wellbeing. Impaired immune function is another symptom, making individuals more susceptible to infections. Additionally, hair loss and impaired wound healing have been associated with vitamin D deficiency. Recognising these symptoms is vital for prompt intervention through dietary changes, sunlight exposure, and, when necessary, supplementation to address the deficiency and prevent long-term health complications. If someone suspects they have vitamin D deficiency, consulting a healthcare professional for appropriate testing and guidance is recommended.
Vitamin D supplements are available at the pharmacy or health food stores, and they usually comes in a version called vitamin D3 or cholecalciferol. You can buy this on its own or combined with other vitamins such as calcium, or in multivitamins. If you are in a high-risk group or for anyone living in the UK in winter, you do not need to check vitamin D levels, you can just start taking supplements. If you are worried, you can get your levels checked in a blood test from a private clinic or lab.
Vitamin D comes as tablets, capsules, oral sprays or oral liquids. You can take it daily or at a higher dose weekly. It comes in a variety of strengths, depending on your personal preference.
Vitamin D is a fat-soluble vitamin, which means that you maximise absorption by taking it with healthy fats such as avocados, nuts, seeds, eggs, or a dressing made with olive oil.
Vitamin D is considered safe for most people to take. If you take certain medications, you may need to check with your doctor before starting vitamin D. These include digoxin or so-called water tablets (diuretics) such as bendroflumethiazide, budesonide, indapamide and spironolactone.
You can speak to your local pharmacist or book a routine visit with your doctor if you are concerned you have vitamin D deficiency or have any symptoms.
Your doctor will ask you about your past medical history, any current symptoms and any risk factors for vitamin D deficiency. They may do a general examination and give you advice. You are recommended to eat a broad balanced diet, and if you are at higher risk of vitamin D deficiency then you may not need to do a blood test but just take vitamin D supplementation.
If you do test and your vitamin D level is slightly lower than normal (‘vitamin D insufficiency’), or it is the winter months, or you are in a group that is higher risk (any heritage other than white caucasian, or live in a country with low sunshine exposure such as the UK), your doctor will suggest you buy supplements yourself. If your doctor advises a test, and it shows a severe vitamin D deficiency then your doctor will prescribe you vitamin D supplementation, this will be a higher amount than people who are taking vitamin D for maintenance in the winter months.
