I have never had my vit D checked so I can't say anything about that, but I have been taking vit D during the winter months for the past 3 years and I am happy to say i haven't gotten a cold at least in the last 3 years. Typically I get 1 -2 colds that last 3-4 weeks every single year. So if it isn't helping the UC, which I think it helps me a little bit especially when the sun disappears for a few months, I think it really helps in the cold/virus arena.
