Vitamin D Status Prevents Infections

Hospital-acquired infections are a nasty public health problem and also serve as a living laboratory to help determine nutritional variables that boost immunity. New research shows that a person with low vitamin D has greater than double the chance of contracting a nasty infection during a hospital stay. The study has broad public health implications. Quite possibly our society should focus on vitamin D status instead of flu vaccines.

It is obvious that vitamin D is required for the proper function of front line immunity (innate immunity) as well as launching a more advanced immune response (adaptive immunity). It is also obvious that societal paranoia about sun exposure and the lack of sun in most of the U.S. during the winter leaves a majority of Americans vitamin D compromised. If vitamin D status can prevent getting even the nastiest infections hospitals have to offer, then imagine what it can do for the general immune function of those walking about in social settings wherein various germs permeate the air during the cold and flu season.

I have previously explained the important role of vitamin D and other nutrients in preventing and combating the flu. I have also reported on a clinical study showing that only 1200 IU of vitamin D per day in children can cut the risk of getting the flu by 50 percent.

In fact, scientists have convincingly argued that it is well people who lack vitamin D that are as much to blame for flu transmission as anyone else. 

The fact that public health officials are obsessed with vaccines for all, even though they consistently produce feeble results, and fail to make any effort to ensure vitamin D adequacy in our society speaks volumes about their actual agenda and the money that sponsors their gibberish.

Ensuring you and your family members are adequate in vitamin D is one of the most important nutrition basics for healthy immunity, not only for the flu season but for immune function in general. When there is a lack of sun then I suggest 2000 IU of vitamin D. Experts have pointed out that many people will need far higher doses to get their vitamin D levels adequate for optimal immunity.  Most people can easily take doses of 4,000 IU – 10,000 IU units all winter. Since it is possible to get too much vitamin D a simple blood test can ensure all is well, which I also recommend especially if a person is using higher amounts over an extended period of time. 

The bottom line is fairly simple:  Ensure you are adequate in vitamin D and you are much less likely to get or transmit the flu.
