With all the news in the press about the benefits of having good levels of vitamin D, e.g. prevention of cancer, especially breast cancer, heart disease, Type 2 diabetes and osteoporosis, it is important that you know whether or not you are lacking in this vital vitamin by taking a simple blood test.

What is Vitamin D?

There are two types of vitamin D: 25-hydroxyvitamin D (25-OHT) and 1,25-dihydroxy vitamin D (1,25-D).

Both types of Vitamin D play many roles in your body, such as helping you absorb calcium, regulate blood sugar levels and maintain healthy bones.

It is essential for bone growth and development, muscle function and normal cell division.

However, most people don't produce enough vitamin D because they spend less time outside under the sun and use sunscreen regularly.

Vitamin D is essential for the absorption of calcium and phosphorus, which help build strong bones.

In addition, vitamin D helps regulate blood levels of parathyroid hormone, which regulates how much calcium is absorbed in your body.

Vitamin D also plays a role in cell growth regulation, immune function, muscle contraction, insulin production, and many other functions

There is growing evidence that vitamin D deficiency may increase the risk of several chronic diseases, including cardiovascular disease, type 2 diabetes, multiple sclerosis, rheumatoid arthritis and some forms of cancer.

Some studies suggest that vitamin D supplementation may reduce the risk of developing these conditions.

What does your diet have to do with getting enough vitamin D?

Vitamin D is one of the most important nutrients you need every day.

It helps your body absorb calcium and phosphorus, both of which help build strong bones.

A healthy adult needs about 400 ius micrograms of vitamin D per day.

Natural food sources of vitamin D are few. It is found in oily fish and eggs. A 100g of grilled salmon contains 284ius of vitamin D and a 100g of tinned pilchards contains 560ius of vitamin D, the yolk of one egg contains about 20ius of vitamin D. And other sources would include fortified foods such as margarines and breakfast cereals.

You can also get vitamin D from sunlight exposure.

But you won’t make up for what you miss during winter.

Most people should consider taking a supplement of vitamin D especially during the winter as you are not going to get enough from food.

The Government advice is that everyone should consider taking a daily vitamin D supplement during the autumn and winter.

Symptoms and Causes of Vitamin D deficiency

Vitamin D deficiency is one of the most common nutritional deficiencies worldwide.

In fact, according to the World Health Organization, it affects nearly 2 billion people globally.

Vitamin D deficiency can be caused by multiple reasons. Some people are born without enough vitamin D receptors in their skin.

Others may not absorb enough vitamin D such as Coeliacs because of fat malabsorption.

Weight loss surgery can affect how much vitamin D you absorb from food.

Vitamin D deficiency is common among older adults.

A recent study found that nearly half of those over age 65 had low levels of vitamin D.

This is especially true for people living in areas where there is little sun exposure during the winter months.

As we age, our bodies produce less vitamin D in our skin. If you spend most of your day indoors, it’s easy to become deficient.

How much vitamin D should you have in your blood?

You want an optimal level of vitamin D in your blood and a simple finger prick test with the sample collected at home can tell if you have enough vitamin D in your system.

At home, vitamin D tests

At home finger prick blood tests are easy to use and can help assess whether you need to take a vitamin D3 supplement and how much you should take.

The test result shows you how much vitamin D you have in your blood.

You'll want to check your levels every 3 months, depending on your age, skin tone, and lifestyle.

Who should test for vitamin D deficiency?

It is important to have optimal levels of vitamin D and because a lack of vitamin D is connected to so many health issues, it is crucial that you know whether you are deficient or not, in this essential nutrient.

It is especially important to test if you spend most of your day indoors because your body will not produce enough vitamin D in response to limited exposure to sunlight.

If you have an auto-immune condition like rheumatoid, arthritis, multiple sclerosis and Coeliac disease it is important to test for vitamin D deficiency as this nutrient D helps to balance your immune function.

Other people with certain conditions such as cancer, diabetes, and kidney failure can also benefit from testing.

Gastric bypass patients are less capable of absorbing fat-soluble vitamins like A, E, K, and D. This makes it harder for them to meet their daily needs.

Vegans and vegetarians are restricted in what foods contain vitamin D

A vitamin D deficiency can lead to serious health issues including osteoporosis, kidney stones, high blood pressure, diabetes, heart disease, depression and certain types of cancers.

Symptoms include fatigue, weight loss, nausea, vomiting, constipation, abdominal pain, joint pain and headaches.

Who does vitamin D deficiency affect?

A vitamin D deficiency can affect everyone. But it’s easy to overlook symptoms such as fatigue, muscle weakness, depression, anxiety, poor sleep and pain.

Vitamin D deficiency symptoms in children

A study published in Paediatrics found that vitamin D deficiency could affect babies' growth and teeth development.

Researchers analysed data from over 3,400 infants born in California between 2011 and 2013.

They discovered that low levels of vitamin D during pregnancy and early childhood are linked to lower birth weight and shorter length.

Babies born with rickets had smaller heads and longer legs compared to those without it.

We also have rickets back in the UK in children, which we thought was eliminated over 40 years ago.

Vitamin D deficiency symptoms in adults

Vitamin D deficiency is very common due to lack of sunshine.

In fact, it is estimated that up to 90% of Americans and Europeans suffer from low levels of vitamin D.

Most people don't realise that they should start taking a supplement of vitamin D until they have had a blood test and realise they are deficient.

You might not connect you are suffering from a lack of vitamin D.

Signs include muscle weakness, fatigue, depression, chronic pain, insomnia and poor immune function.

Symptoms of vitamin D deficiency can occur over a period of months or years.

People who are taking medications that prevent the body from absorbing vitamin D may require additional supplementation to achieve optimal levels.

Some examples of drugs that interfere with vitamin D absorption include antacids, proton pump inhibitors (PPIs), H2 blockers, and iron supplements.

Who should take vitamin D supplements?

As well as all of these benefits, it is now thought that having good levels of vitamin D can help slow down the ageing process and when taken in pregnancy and childhood could wipe out 80% of multiple sclerosis cases.

Vitamin D deficiencies have also been implicated in other autoimmune diseases such as rheumatoid arthritis, lupus and inflammatory bowel disease.

If you suffer from joint pains, it is important that you are checked for vitamin D deficiency because research has shown that people with musculoskeletal pain, e.g. low back pain, are often deficient in vitamin D and when the vitamin D deficiency is corrected by vitamin D supplement, the pain is eliminated.

If you have been told that you have high cholesterol, make sure you change your diet and get your vitamin D level checked.

Cholesterol is used to make vitamin D so if you are deficient in vitamin D, your liver can be producing more cholesterol to try and produce more vitamin D.

By correcting the vitamin D deficiency, your body does not have to produce so much cholesterol.

And if you are trying to get pregnant or having recurrent miscarriages then it is important that your vitamin D level is checked because it is known that having good levels of vitamin D helps the body maintain a pregnancy by effectively switching off the part of the immune system that could reject a baby as only half the DNA is the mothers.

How accurate are vitamin D tests? Do home vitamin D blood tests work?

The most accurate way is to take a blood sample and this can be collected at home using a finger prick kit supplied by the lab.
