What is vitamin D?
Vitamin D is a fat-soluble vitamin, meaning it’s absorbed by the body through fatty tissue and then stored in these tissues or the liver
It is made in the body from cholesterol when the skin is exposed to natural sunlight (without sunscreen)
Unlike most vitamins, vitamin D functions more like a hormone: every cell in your body has a receptor that allows it to absorb the mineral
What does vitamin D do?
activates cells that fight infection and reduce inflammation
maintains and builds bone strength by aiding the absorption of calcium from your gut and kidneys
What foods contain vitamin D?
Vitamin D is found mainly in animal products such as:
Fish such as salmon, mackerel, sardines and tuna
Milk, butter and cheese
If you are vegetarian or vegan, it’s likely that you’ll need to supplement to get the right level of vitamin D.
Other vitamins linked to Vitamin D
Magnesium assists in the activation of vitamin D in the body
Vitamin D stimulates the absorption of calcium, which is important for bone health
Vitamin D deficiency - who is at greatest risk?
Anyone who lives in the northern hemisphere - that includes the UK
If you spend most of your time indoors
Those who eat very little fish or dairy
The link between vitamin D and overall health:
Some studies have shown that low levels of vitamin D have been linked to a number of medical conditions including:
Type 2 diabetes
Dementia and Alzheimer’s
It is not possible to say that vitamin D deficiency causes any of the list above, but there is a scientific rationale to keeping your vitamin D levels optimised.
What are the UK guidelines?
The NHS recommends that from October to March, everyone should consider supplementing with Vitamin D and there is special advice for babies, infants, children and breastfeeding women. Read the current guidelines here: https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-d/
How do I get tested?
Your GP can arrange a blood test for vitamin D or it can be arranged privately via a Registered Nutritional Therapist as part of a consultation. It’s important to know your current level of vitamin D to determine the level of supplementation required; levels may be considered “normal” or “adequate”, but Nutritional Therapists aim for optimal levels of nutrients for the best possible health.
