Some evidence vitamin D might fight colds
A daily vitamin D supplement may help young men enjoy more sick-free days during cold and flu season, a small study suggests.
Vitamin D has been the subject of much research of late, with studies linking low vitamin D levels in the blood to higher risks of type 1 diabetes and severe asthma attacks in children and, in adults, heart disease, certain cancers and depression.
But whether vitamin D is the reason for the excess risks — and whether taking supplements can curb those risks — has yet to be shown.
The body naturally synthesizes vitamin D when the skin is exposed to sunlight.
