Vitamin C and the common winter cold
Canadian winters are known to be brutally cold and are often accompanied by a brutal cold. The lovely symptoms include cough, fever, and sore throat to name a few. Colds can stick around up to 10 days, and may make your life miserable. I’m sure you’ve all heard someone at some point mention vitamin C in the context of prevention/treatment. The theory is that since vitamin C is an antioxidant it would reduce oxidative stress when you encounter an infection – but does science offer any proof to this?
I came across a great review paper published by Hemilä and Chalker (2010), and their objective was to determine if vitamin C intake reduced the length, severity (symptom scoring/days kept indoors), or the number of colds when used before or after cold symptoms
To summarize, the results are as follows:
There was no effect on the number of colds. The duration of the cold was reduced, with a greater effect in children, only when taken prior to symptoms. The severity of the cold was not affected by vitamin C
Will vitamin C help you with your cold? Probably not. Should you continuously take vitamin C to reduce potential duration? I say if it’s vitamin C from food, why not- there are a lot of other benefits from doing this. Unfortunately these studies did not have vitamin C administered from food, which is the best way to get your vitamins.
Put a lemon in your water occasionally, won’t get rid of your cold but it will make drinking water a lot tastier!

Hey There,Thanks for the information.
I was wondering if any research was done in relation to probiotics and cold prevention.
Also as a dental healthcare professional , many of my patients love to drink water with lemon and mint during the summer months. I always remind them to have a drink of water right after they are done (with the water and lemon) …. so they can rinse off the acidity from the lemon. If consumes on a daily basis for some people that have gum recessions and /or sensitive teeth: drinking water with lemon may contribute to increase in sensitivity. Personally In the hot summer months (that hopefully will be coming soon:)…) I find water and lemon very refreshing.

Thanks for your input, Rita! A great example of why healthcare should be a multidisciplinary approach. That’s interesting you mention that, I recently read a paper on the effect of fruit smoothies and sensitivity. I’m trying to keep that in mind! I will get to probiotics very soon :) Thanks for your comment!
