Vitamin D is known to be an important nutrient for immune system function. Good vitamin D levels decrease allergy, protect against chest infection, and can even improve constipation. From May to September, in Melbourne, we cannot make vitamin D from sun exposure because of the changes in the angle of the sun during the winter months.

The main dietary sources of vitamin D include oily fish, mushrooms, liver, and eggs. If these are not part of your diet, a supplement may be useful. Vitamin D supplements are readily available and asking your GP to measure your vitamin D levels when you next have an appointment is a great idea. Stay warm and healthy over Winter time!
