A review of 30 studies involving more than 11,000 people who took at least 200 mg of vitamin C daily found that it offered little protection in reducing the length or severity of common colds for most people. It did work for some people, such as marathon runners and skiers, who undergo periods of high stress, but the study’s authors say the rest of us shouldn’t bother taking it.
That was the problem right there. I didn;t read the whole thing but that caught my eye.
