More about Vitamin D and the Flu

Finally, SOMEBODY is talking about the vitamin D—influenza connection.   Researchers see link between vitamin D, flu immunity:

–In February, researchers reported a link between vitamin D levels in the blood and upper respiratory infections in a group of nearly 19,000 people ages 12 and older.
–A 2006 review article in the journal Epidemiology of Infection laid out a detailed case for vitamin D and its protective effect against the flu.

Best thing you can do for you and your families to protect them from the flu, swine, avian, or otherwise, is to take 1,000 IU vitamin D per 30 pounds body weight (if you’re not getting summer sun exposure without sunscreen—if you are, start supplementing when the time of year comes that your shadow is taller than you are—a rule of thumb for whether or not the sun is strong enough to produce vitamin D in your skin. I predict that once studies are done, they will show that having a 25-OH vitamin D level between 50 and 100 ng/ml is better at preventing flu than any vaccine—not to mention reducing the risk of many common and deadly forms of cancer.

Vitamin D and Flu

With all the media coverage of the “swine flu” (H1N1) non-epidemic, I haven’t heard a single expert mention what could well be the most effective public health measure in preventing a pandemic—the recommendation for everyone to take enough vitamin D3 (or get enough un-blocked summer sun exposure) to get their 25-hydroxy vitamin D blood level above 50 ng/ml (but not more than 100 ng/ml). A good rule of thumb for supplementation is 1,000 IU for every 30 pounds of body weight. If your health insurance won’t cover the cost of a vitamin D test, the least expensive way ($65) to check your level is a home test kit available through the vitamin D council’s website, unless you live in NY, in which case you’ll have to get your doctor to order a blood test for you.
