• Vitamin D: mainly sunlight, but is also found in some foods such as eggs, fish, while some milks and margarine brands may be fortified with it.

These micronutrients play important roles in both the innate and adaptive immune systems in the production of different types of cells.

In addition to this, vitamin A and zinc helps to maintain the integrity of the skin and lining of vital organs and the respiratory system (which are part of the innate immune system).

Vitamin B12 and iron are also essential for the production of haemoglobin which carries oxygen in the blood.

Vitamin C, E and selenium help to control inflammation by mopping up the impact of oxidative stress produced by free radicals that pierce cell walls causing the contents to leak.
