For a few years now I've always taken Vitamin D during the winter and felt it helped reduce the incidence and severity of colds I would get. Now a just published shows that giving vitamin D to school children reduced the incidence of influenza. We should all be having our Vitamin D levels checked, especially if we are one to get a lot of colds each year. Taking 1000-2000IU/day through the winter may be your best bet if you cannot get your blood tested. There is almost no risk of developing any toxicity at 2000IU/day, unless you already had high levels of D in your blood.
