Vitamin D

Vitamin D

Vitamin D helps us absorb calcium and phosphorus and therefore plays an important role in the health of our bones. The main source of vitamin D is from exposure of our skin to sunlight. However, many Australians don’t have adequate levels of vitamin D, especially in the winter months or if they spend little time outside.

Sources include

  • Egg yolk
  • Exposure of our skin to sunlight
  • Liver
  • Oily fish such as salmon, tuna, mackerel and herring
  • Some food are fortified with vitamin D, e.g. milk products
