Our best winter vitamins

Winter is a time when we can all experience an increase in coughs and colds – for some it might feel like the winter season brings a series of infections, one after the other. Modern day life can be detrimental to normal immune function - stress, pollution, nutritional deficiencies, poor digestive health, among others, can all put a strain on the immune system, leaving it more vulnerable to attack. Specific nutrients which contribute to immune system function include vitamins A, B6, folate, vitamin B12, vitamin C, vitamin D, selenium, zinc and iron.
