Get Yer Vitamins! 

I know a number of people who, at the beginning of cold season or even just all the time, take mega doses of vitamin C in the hopes that it will make them less prone to catching a cold. I know many more (myself included) who start pounding the vitamin C as soon as we get sick.

It turns out that we may all be wasting our money and unduly increasing our risk of kidney stones (an effect of vitamin C overdose): a new meta-study suggests that vitamin c supplementation does not reduce the likelihood of catching cold, and only reduces the duration of a caught one by a half a day. The study did indicate that taking vitamin C was beneficial to those regularly exposed to high physical stress, such as skiers or runners. They don't seem to have addressed other types of stress.
