Can vitamin C really help with chills and sneezes this winter?
Vitamin C is an effective water-soluble antioxidant, able to trap reactive oxygen species (ROS). It forms part of the antioxidant defense system of phagocytes. A comprehensive meta-analysis in 2013 concluded that a dose of 200 mg per day of vitamin C reduces the duration of colds. A recent study suggests that this effect is due to the improved migration of virus-killing neutrophils through chemotaxis.
