Influenza and Vitamin D
Influenza kill around 35,000 Americans every year and similar viruses cause additional mortality and untold morbidity.
Dr. John Cannell, who heads the nearly broke non-profit educational organization, the Vitamin D Council, now says most of those deaths could be prevented if Americans, and their doctors, understood some simple facts:
· Vitamin D is not a vitamin, but a steroid hormone precursor, which has profound effects on innate immunity.
· The amount of vitamin D in most food and nearly all multivitamins is literally inconsequential.
· The correct daily dose of vitamin D for adults is approximately 5,000 IU/day, not the 200-600 IU recommended by the Institute of Medicine, the National Institutes of Medicine and the FDA.
· The only blood test to determine vitamin D adequacy is a 25-hydroxy-vitamin D, not the 1,25-di-hydroxy-vitamin D test many physicians now order.
· Healthy vitamin D blood levels are between 50-80 ng/ml, levels obtained by fewer than 5% of Americans.

Dear Dr. Cannell:
RE the emerging spring-2009 swine flu pandemic: Despite the Vitamin D Council's current financial woes, you have a moral responsibility here.
My bet is the CDC may "go out on a limb", any day now, and start recommending that all adults (and most children), begin taking vitamin D supplements (at or above the levels you have been recommending for a while).
If I'm right, and vitamin D supplements suddenly disappear from grocery & drug store shelves, almost overnight, it will be especially critical for the Vitamin D Council to post information about "sun-bathing" for vitamin D.
My best,
Diane
