Cold-fX prevents the common cold

Many news reports reference a new Canadian gov't approved study suggesting that Cold-fX prevents the common cold.

It's true that the study is good and scientifically valid...but the actual benefits shown are very modest.

Cold-fX seems to reduce the number of colds by half. But this benefit is only in people who usually get two or more colds per season...and it may not help prevent the FIRST cold of the season.
