    What is vitamin D?

    Vitamin D helps to keep the calcium and phosphate in your body in check. Calcium and phosphate play an important role in keeping your bones, muscles and teeth healthy.

    A lack of vitamin D can lead to low bone density, where brittle bones and deformities may occur. So you’re less likely to experience these complications if you get the right amount.

    Often referred to as the sunshine vitamin, you’ll get most of it from the sun, although that isn’t always easy because we aren’t able to get that much exposure to the sun. That’s why it’s recommended that you take supplements in order to keep your levels healthy. Buying vitamin D online is the simplest way of preventing and treating deficiencies.

    Who needs vitamin D?

    Everyone. Vitamin D not only affects your bones, teeth and muscles, but your mood and your immune system too. Vitamin D deficiencies have been linked to depression, muscle cramps and, in the most severe cases, osteoporosis, which is where your bones are so brittle they break easily or become deformed.

    How common is vitamin D deficiency?

    It’s estimated that over a billion people worldwide suffer from some form of vitamin D deficiency. It can be easily avoided though. Supplements and treatments are usually very affordable, even if you need a high strength treatment.

    Sourcing guidelines:

    When we present you with stats, data, opinion or a consensus, we’ll tell you where this came from. And we’ll only present data as clinically reliable if it’s come from a reputable source, such as a state or government-funded health body, a peer-reviewed medical journal, or a recognised analytics or data body. Read more in our editorial policy.

    What causes vitamin D deficiency?

    There are a range of factors that can cause vitamin D deficiency, but it’s usually due to a lack of sunlight. As your body gets most of its vitamin D from the sun (or at least it should) this can be due to the lifestyle we lead today wherein we spend most of our time indoors. This isn’t to say that the sun is the only source of vitamin D; you also get a small amount from food, as well as fortified food (where vitamin D has been added) such as cereals and margarines.

    What are the symptoms of vitamin D deficiency?

    It’s not only serious vitamin D deficiencies that can cause health problems. Less severe vitamin D symptoms include depression, general aches and pains and low energy.[4] If you notice these symptoms or if you spend much of your time indoors, there’s a good chance that you’re suffering from a lack of Vitamin D. Taking a daily supplement is one of the most efficient ways of avoiding or treating these symptoms.

    The vitamin D supplement dose is much lower than those given for treatments, but you should still not exceed the recommended daily dose. Daily maintenance doses are the best way to keep your vitamin D levels healthy and stop more serious issues from happening.

    Can vitamin D deficiency lead to other problems?

    A severe lack of vitamin D can lead to a bone condition called osteoporosis. This is where a lack of calcium leads to brittle bones that are easily broken, or even serious deformities.

    Severe vitamin D deficiency symptoms can be caught early if you notice muscle cramps, joint pain, delayed wound healing and general fatigue. These can be early warning signs that a severe vitamin D deficiency is developing.

    High levels of vitamin D over a number of weeks can treat this condition, although they’ll not completely reverse its effects. All treatments for severe vitamin D deficiencies will need a prescription, as well as careful monitoring by our doctor. Vitamin D deficiency treatment doses usually depend on the severity of your condition.

    What medications are there for vitamin D deficiency?

    There are three main reasons why you might want to take vitamin D: as a supplement to avoid your levels becoming too low; as a treatment for severe deficiencies; or as a maintenance dose, which you’ll likely need after treatment (and should continue taking regularly).

    Supplements are the lowest doses of vitamin D. They’re effective for prevention and treating milder deficiencies. These products can be bought over the counter from your local pharmacist.

    Treatment doses are more varied than those used as a supplement. They’re generally taken over a specific period of time to tackle severe deficiencies as quickly and safely as possible. After this, it’s likely that you’ll need to keep taking a maintenance dose.

    Is there a ‘best’ treatment for vitamin D deficiency?

    ‘Best’ will depend on what you’re taking it to help with. If you’re just looking to prevent any vitamin D deficiencies from setting in, then you’ll only have to take a low dose, whereas you’ll need a higher dose to treat any symptoms of a deficiency that’s already happened.

    Vitamin D can come in a range of forms as well, from tablets to granules . As well as this, they can contain different ingredients, so some vitamin D supplements and treatments can be more suitable for vegetarians or vegans, as well as being kosher or halal friendly.

    So what’s best for you might not be best for someone else. If you’re unsure of which vitamin D could be best for you, speak with our doctor. They can advise you on what can be the most suitable form of vitamin D for your needs and lifestyle.

    Does vitamin D deficiency always need treatment?

    Many people can become a bit deficient in vitamin D throughout the winter, and it won’t always lead to more severe deficiencies. However you will be healthier during this period if you’re making sure that you’re getting enough vitamin D to keep your body and mind working properly.

    More severe vitamin D deficiencies, though, should be treated. This is because having low levels of vitamin D for long periods of time can easily lead to osteoporosis.

    FAQ: Vitamin D deficiency

    Have something specific you want to know about Vitamin D deficiency? Search our info below, or ask our experts a question if you can’t find what you’re looking for.

    How is vitamin D deficiency diagnosed?

    You’ll usually be able to diagnose a growing deficiency in vitamin D through a blood test. Your doctor will also check with you about common symptoms of vitamin D deficiency, such as fatigue, cramps and pain in your joints, especially if you’re noticing these issues in the autumn or winter months.

    Are there different types of vitamin D?

    Vitamin D2 and vitamin D3 are different forms of vitamin D that come from different sources (vitamin D2 comes from vegetable sources, while vitamin D3 comes from animal sources).

    You can get vitamin D2 and D3 supplements, but vitamin D3 is better processed in the body, as well as more easily stored. Supplements are synthetic versions of these vitamins. Vitamin D3, for example, comes in a form called colecalciferol, while vitamin D2 supplements are called ergocalciferol. Essentially, both vitamin D forms work in the same way (by regulating calcium levels) but vitamin D3 is generally considered to be a better option than D2. Because of this, it’s the form of vitamin D that you’ll most commonly see.

    Are there tests for vitamin D deficiency?

    Yes. There are blood tests that can check to see if you’re suffering from a vitamin D deficiency. Your doctor will advise you on the medication that you need to take to bring your vitamin D levels within the normal range. The dosage and duration will depend on the severity as well as our overall health condition.

    Vitamin D supplements and treatments are usually available over the counter. But you should always consult a doctor to know which one’s suitable for you to take. The doctor will also be able to tell you about the right dose and how long you need to take it for.

    Can you get side effects from vitamin D supplements?

    For the most part, it’s very unlikely you’ll experience any problems or side effects with vitamin D. Even the most common issues present in less than 1 in 100 people, and in many of these cases it occurs when the recommended dose has been exceeded.

    The most common side effects are hypercalciuria (too much calcium in the urine) and hypercalcemia (too much calcium in the blood).

    Hypercalcemia is a dangerous condition that needs immediate medical attention. Symptoms are constipation, loss of appetite, headaches, confusion, depression, excessive thirst, abdominal pain, tiredness and muscle pain.

    Allergic reactions are rare, but it’s important that you know what to look for in case they do happen. Seek immediate medical attention if you notice any of the following: swollen lips, mouth, throat, face, severe itching, hives and difficulty breathing.

    Do vitamin D supplements always work?

    Yes. You might not always notice that it’s working, but taking the right amount of vitamin D, especially during winter, will help to keep you healthy until you can get a good amount of vitamin D from sunlight again.
