Vitamin D is a fat soluble vitamin the body naturally makes when exposed to sunshine or certain foods.

Sunshines helps the body to absorb Vitamin D. It has been suggested that we sit in the sunshine for 5-30 minutes per day. 90% of Vitamin D comes from exposure to sun. 

Vitamin D regulates the levels of calcium and phosphate in the body and keeps bones, teeth and muscles fit and healthy.

Symptoms of low Vitamin D

Lack of Vitamin D can lead to deformities such as Rickets in children and bone pain caused by Osteomalacia in adults.

How do we get Vitamin D?

  • Dairy products

  • Oily fish, Salmon, Sardines, Herring & Mackerel

  • Egg Yolks

  • Mushrooms (some have more Vitamin D than others)

  • Red Meat

  • Liver

  • Fortified foods such as some fat spreads and breakfast cereals

Very little Vitamin D comes from diet, it comes mainly from being exposed to the sun. The body does the rest.

What affects Vitamin D levels?

  • Lifestyle - if we do less outdoor activities, busy indoor lives, working from home

  • Clothing - if we are more covered up at certain times of the year

  • Diet - are we eating enough food and variety of foods

  • Obesity - better Vitamin D levels can help lose weight

Who is more at risk from Vitamin D deficiency?

  • Pregnant people and those who are breastfeeding

  • If you have darker skin, for example African, African-Caribbean or South Asian backgrounds

  • Wearing whole body coverings

  • Skin cancer patients who need to avoid the sun

  • Elderly

  • Those who spend a lot of time indoors and get little sun exposure

How do we give Vitamin D supplements

Boosters are given intramuscularly usually in the upper arm and be done twice yearly, dependent on an individuals needs and levels. It is always best to discuss this option with a healthcare professional.

How do I get my Vitamin D levels?

You can find out your Vitamin D levels with a simple blood test from either your GP or by a simple test at home kit. If they are on the low side you can have a Vitamin D booster twice a year to boost your levels. If you are deficient in Vitamin D it is best to be followed up with a yearly blood test.

The NHS has suggested that we should be taking supplements of Vitamin D of 10  micrograms (400IU) daily between October and Early March to keep bones, teeth, muscles etc healthy.

Vitamin D may help you boost your white blood cells which enable you to fight infections better. 

Is Oral Vitamin D enough?

It is easily accessible and inexpensive BUT has to be taken every day or you will not get the relevant dose.
