The notion that popping vitamin C supplements will automatically ward off the common cold has been debunked by experts. According to Daniel M Davis, head of life sciences at Imperial College London, this idea has persisted for over 50 years largely due to the advocacy of Linus Pauling, a double Nobel prize winner and influential chemist.
Pauling's 1970 book Vitamin C and the Common Cold made waves, sparking high demand that led to the production of supplements on an industrial scale. However, Davis notes that research has shown no correlation between vitamin C supplementation and reduced cold-catching rates. In fact, studies indicate that individuals taking vitamin C supplements are just as susceptible to catching a cold as those who don't take any.
The modest benefits reported in some studies – about an 8% reduction in symptom duration for adults – are also tempered by the realization that individuals regularly taking high doses of vitamin C tend to be more health-conscious overall. Therefore, Davis suggests focusing on vitamin D if one wants to bolster their immune system.
Unlike its cousin, vitamin D is better established as crucial for immunity and can be readily obtained through sun exposure between March and October or taken as a supplement during the winter months, according to NHS guidelines.
