To reduce the incidence of type 1 diabetes, we should give 2000 IU of vitamin D3 to our newborns until age 1. A study in the Netherlands of more than 100,000 children and 31 years of follow-up showed that vitamin D3 at 2000 IU reduced the incidence of type 1 diabetes by 88%. No untoward side effects were found. I tell this to all parents of newborns. Vitamin D is an important immunoregulator that reduces inflammatory cytokines and obviously antibodies. It also reduced influenza A by 42% in a study in Japan for preschool children.—PAUL BATTLE, PA-C, Denver (217-5)
