In brief: Prevent? not treat
Vitamin c may help *prevent* the common cold [studies disagree].
But, alas, vitamin c doesn't shake loose the common cold once it's grabbed a hold of you.

In brief: No
While vitamin c is an antioxidant.
It is not the cure for the common cold. It may decrease your chances of acquiring viruses, but it does not reduce the chances to zero.

In brief: Yes
Linus pauling studied the effects of vitamin c on colds and reported that it can be effective.
Some people find it effective for themselves while others do not.

In brief: No
High doses of vitamin c were popularized by linus pauling, a respected scientist with no medical training.
So far studies on the topic have not demonstrated any benefit to high doses (or low doses) in either preventing or reducing the length or intensity of the common cold.

Research shows in most situations, taking vitamin c does not prevent colds, but in those who do extreme physical exertion or are exposed to cold temperatures it's a useful preventive- see http://www.
Ncbi.Nlm.Nih.Gov/pubmed/15495002?Dopt=abstrct . Studies show vit c reduces duration of cold symptoms. High doses at onset may be especially helpful- see http://www.Vitamincfoundation.Org/surefire.Shtml.

In brief: Yes
And no..........As you can see, the jury is still out.
My recommendation to patients is that "normal" doses can't hurt in preventing or treating colds, but that high doses (megadoses as advocated by linus pauling) can be harmful to the body. Moderation.

Vitamin c has been proved effective against the common cold, but it must be taken regularly as a preventive tool.
Taking it when your sick is too late.
