Vitamin D Test

Vitamin D, also know as cholecalciferol, is a nutrient that is needed for healthy bones and muscles. If you lack Vitamin D, this could lead to bone deformities such as Rickets and Osteomalacia in children and adults respectively. You may need a Vitamin D Blood Test in order to find out if you are Vitamin D deficient.

Most people will get all the Vitamin D they need from sunlight; however, Vitamin D can also be found in food such as:

  • Fish (Mackerel, Salmon, Sardines, etc.)
  • Egg yolks
  • Red meat
  • Liver
  • And different types of fortified foods (Cereal)

How much Vitamin D you need?

For an Adult, 10mcg’s of Vitamin D is needed a Day.

During Autumn and Winter some people are not exposed to enough through just sunlight which can lead to a Vitamin D Deficiency. This is because the sun is usually not strong enough to make your body start producing Vitamin D.

Some people get enough Vitamin D through their diets, however, it is recommended that you take supplements if you do not go outside often or if your diet does not contain the mentioned foods, otherwise you may suffer from a Vitamin D Deficiency.

Taking too much Vitamin D could also be detrimental to you and your health, and if you take too many Vitamin D Supplements over a prolonged period of time this can cause too much calcium to build up in the body causing a condition called hypercalcaemia. So if you take vitamin supplements, for most cases 10mcg per day will be enough. 

If you would like to check if you do have Vitamin D deficiency, come see us at any one of our 18 clinics or book a home test. We can evaluate your Vitamin D levels as a stand alone or as part of a broader vitamin and nutrition profile or health screening
