As readers from 3 years ago remember, this newsletter first published

evidence vitamin D would prevent influenza and many varieties of the

common cold in 2005:


I then published the theory in:                                                     


Cannell JJ, et al. Epidemic influenza and vitamin D. Epidemiology and Infection. 2006 Dec;134(6):1129-40.


As Science News reported, I realized this after observing an influenza epidemic at Atascadero State Hospital.


The antibiotic vitamin: deficiency in vitamin D may predispose people to infection.  Science News, November 11, 2006


Last year, we used vitamin D to explain virtually all of the many unsolved mysteries of influenza.

Our second influenza paper is by far the most accessed paper in the journal this year.

Today, researchers from Harvard and the University of Colorado, writing in the Archives of Internal Medicine, published convincing evidence my observations at Atascadero State Hospital were correct.

Influenza kill around 35,000 Americans every year and similar viruses cause additional mortality and untold morbidity. As I have said, It appears Linus Pauling was right about everything he said about vitamin C, but he was off by one letter. The Vitamin D Council, the nearly broke non-profit educational organization, now believes most influenza deaths and many other respiratory infections, like the common cold, 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.

·         Medicare’s new proposed rule change, which forbids Medicare carriers for paying for virtually all vitamin D blood tests (Draft LCD for Vitamin D Assay Testing (DL29510), will kill tens of thousands of Americans yearly.

·         The mechanism of action of vitamin D in infection, dramatically increasing the body’s production of broad-spectrum natural antibiotics (anti-microbial peptides or AMP) suggests pharmaceutical doses of vitamin D (1,000 IU per pound of body weight per day for several days) will effectively treat not only influenza and the common cold, but help treat a host of other seasonal infections, including meningitis, septicemia, and pneumonia, in both children and adults.

·         In 1997, when the Food and Nutrition Board (FNB) set the current guidelines for vitamin D intake, they forgot to correct for the widespread sun avoidance that began in the late 1980’s when the AMA’s Council of Scientific Affairs warned against sun-exposure, and recommended that all Americans should make every effort to never let a photon of sunlight strike their skin.  The failure of the 1997 FNB to compensate for sun-avoidance, has led to millions of deaths around the world.

·         Physicians who ignore vitamin D deficiency will eventually suffer medical-legal consequences.

·         While many think the influenza virus causes influenza, Cannell notes it was George Bernard Shaw who first understood: “The characteristic microbe of a disease might be a symptom instead of a cause.” George Bernard Shaw, (Preface on Doctors, The Doctor’s Dilemma, 1911).

Jim, Thanks for doing what I was considering doing with the above newsletter, all the links from it work so that is great. 

My target blood level has been set at 100mg/mL, of course I do have this history of chronic, persistent bacterial infections for decades by history.  My daily dose is VitD3 10,000IU for the past 4 months and my level elevated to 68ng/mL.  

When I look at the types of chronic diseases in my family lines it is my personal opinion that I am working on prevention of the activation of same by the ingestion of a pharmacetical-level of Vit D3supplementation.  And I also see it as a strong adjunct to support my progression through CAP.

I would value some discussion of the articles cited in this newletter by those who read them.  Always good to get various reads on a topic.
