Vitamin D and Flu Prevention - Does It Work?

Vitamin D and Flu Prevention

April 29, 2010

In a recent study, done on Japanese shool-aged children, it was shown that taking 1,200 IU daily of vitamin D reduces the chance of catching the flu by 58%. Moreover, a surprising finding made by the researchers was that vitamin D reduced the number of children getting an asthma attack related caused by having the flu.

This study was prompted because in an earlier study, researchers found by accident that people taking vitamin D reported less symptoms from the common cold and flu.

Keep in mind that vitamin D only prevented catching influenza A and not influenza B virus. (Influenza B virus happens in the later part of the flu season.)

Bottom Line

Giving 1,200 IU daily of vitamin D to children attending school, especially in those with asthma, can cut down the chances of getting the flu!
