A common myth is that we can 'boost’ our immune systems. As scientists, we know that is not technically true but what we can do is support and reinforce a good, healthy immune function through the intake of the right amount of vitamins and minerals. For example, a Vitamin C deficiency may make us more susceptible to respiratory infections so while we should ensure not to become deficient, taking in extra Vitamin C will not necessarily “boost” our immune system as the body will get rid of excess anyway.
