Vitamin D3 for Fending off the Flu
By Jennifer Morganti, ND, Director of Education for NEEDS

Vitamin D3 may turn out to be one of the must-haves in your medicine chest as the cold and flu season approaches. A four-month study done in Japan on 167 school children found that kids who took 1,200 IU of vitamin D had a 42% reduced risk of contracting the seasonal influenza A infection as compared to the kids who took placebo. Some of the kids in the study had asthma, and it appeared that vitamin D supplementation significantly reduced their risk of having an asthma attack.
