Why is Vitamin D important for the body?
Vitamin D is often said to be used for healthy bones and healthy teeth. This is true, however vitamin
D is used by many other processes in the body. Having adequate levels of Vitamin D will increase
muscle strength, improve the immune system, reduce falls risks and improve mood and energy
levels.
Where do I get vitamin D from?
There are two main sources of vitamin D – food and sunlight. Foods that contain vitamin D include
sardines, tuna, salmon, egg yolks, red meat and liver.
How common is Vitamin D deficiency?
The UK National Diet and Nutrition Survey from 2008-2012 showed 23% of adults aged 19–64 years
and 21% of adults aged 65 years and over suffered from vitamin D deficiency. Another survey which
concluded in 2019 showed that from a population of nearly 6.5 million people, 1/3rd of people were
deficient in Vitamin D.
What symptoms might I feel if I am deficient in vitamin D?
A lot of people with vitamin D deficiency will not have any symptoms.
Sometimes the symptoms might be very vague. Below are some of the symptoms of vitamin D
deficiency:
∙Tiredness
∙Feeling generally unwell
∙Bone pain
∙Muscle aches
∙Joint pain
∙Low mood
Who is at risk of being vitamin D deficient.
The National Institute of Clinical Excellence puts the following people in the high-risk category of
being vitamin D deficient:

∙Those with low exposure to the sun. This may be due to due to cultural reasons, those who
are housebound, or those who are confined to the indoors for long periods
∙Those with darker skin pigmentation
∙Those who have had certain types of abdominal surgery which makes them less able to
absorb vitamin D.
∙Those with severe liver or kidney disease
∙Women who are pregnant or breastfeeding
∙Those who have a body mass index (BMI) greater than 30 kg/m2
How can I get more Vitamin D?
It’s very difficult to get enough Vitamin D from sunlight in the UK. That’s why the UK government
recommends people in the UK take vitamin D supplements during the winter months.
