Low Vitamin D

Normal Vitamin D is >50 but optimal is >75

Vitamin D is required for the maintenance of healthy bones and teeth. It has also been shown to support the function of the immune system, maintenance of normal muscle function and Vitamin D has been in the news recently because of possible links in reducing the incidence of other serious conditions. Vitamin D deficiency is very common, with more than half of the adult population in the UK having insufficient levels of Vitamin D. Most affected people either don’t have symptoms, or have vague aches and pains, and are unaware of the problem.


Vitamin D is also found in a small number of foods.

Sources include:

  • oily fish – such as salmon, sardines, herring, mackerel and fresh tuna
  • red meat
  • liver
  • egg yolks
  • fortified foods – such as most fat spreads and some breakfast cereals


Depending on your Vitamin D level (with the new reference ranges), you will fall into one of 3 categories.

Vitamin D Deficient is less than 25nmol/L  (used to be <10ng/ml)

Vitamin D insufficient is 25-50nmol/L  (used to be 10-20)

Normal Vitamin D is more than 50nmol/L but optimal is >75
