Coughing, sore throat, runny nose, body aches, fatigue. The classic collection of symptoms synonymous with an acute respiratory tract infection. From the common cold right through to the flu, it is something most people are faced with many times over in their life.

In this podcast, I’ll look at the current state of play for the role of supplemental vitamin C, vitamin D and zinc in tackling acute respiratory tract infections.
