Vitamin D Boosts Immunity, Prevents Colds, Swine Flu

Vitamin D may be an important way to arm the immune system against disorders like the common cold, report investigators from the University of Colorado Denver (UC Denver) School of Medicine, Massachusetts General Hospital (MGH) and Children's Hospital Boston.
Another study in Europe concluded that Vitamin D is better than the swine flu vaccine at halting H1N1 infections. In fact, without vitamin D, chances are that a vaccine won't generate much of an immune response in the first place and the best thing about Vitamin D is this : it's affordable.. You can even get it for free (from sunlight).

In the largest and most nationally representative study of the association between vitamin D and respiratory infections, people with the lowest blood vitamin D levels reported having significantly more recent colds or cases of the flu. The risks were even higher for those with chronic respiratory disorders, such as asthma and emphysema.So skip the vaccine. Get more Vitamin D!
