Vitamin D Once Again for Flu

I do not need to add anything to this.

THE Number One Way to Conquer a Cold or Flu: Vitamin D

Vitamin D is an amazingly effective antimicrobial agent, producing 200 to 300 different antimicrobial peptides in your body that kill bacteria, viruses and fungi.

In the United States, the late winter average vitamin D level is only about 15-18 ng/ml, which is considered a very serious deficiency state. It’s estimated that over 95 percent of U.S. senior citizens may be deficient, along with 85 percent of the American public.

In 2009, a team of researcher’s from Children’s Hospital Boston analyzed blood samples taken from 5,000 children under age 12 and found that nearly one out of five children in the U.S. have low blood levels of less than 50 nanomoles per liter, the level recommended by the American Academy of Pediatrics. They also found that two out of three children have a level below 75 nmol/L--which is still insufficient, based on most of the research coming out today.

No wonder colds and flu run rampant each year.

The best source for vitamin D is direct sun exposure. But for many of us, this just isn’t practical during the winter. The next best thing to sunlight is the use of a safe indoor tanning device. If neither natural nor artificial sunlight is an option, then using oral supplements is your best bet.

Remarkably, researchers have found that 2,000 IU of vitamin D per day abolished seasonal influenza. This is somewhat surprising, as it is half the dose of what most adults need to achieve ideal levels of vitamin D
