Cold & Flu Prevention: Vitamin D3 (with K2)

Remember: Having a strong, healthy immune system is the absolute best way to prevent the flu (and all other diseases as well.)

Vitamin D is produced in the body by sunlight and regulates the expression of over 2,000 genes, including those of the immune system. Unfortunately, up to 90 percent of us are deficient in vitamin D.

Recent research shows that low vitamin D levels are linked to higher rates of cold, flu and respiratory infections.

Many functional medicine physicians believe that current recommended daily amounts of vitamin D are far too low, and that 2,000 units a day is the correct dosage for those who are deficient. 

The 25-hydroxy vitamin D test is the most accurate way to measure how much vitamin D is in your body.

In blood tests, the accepted normal range for vitamin D levels runs from 20 to 50 nanograms per milliliter however, MY PERSONAL PHYSICIAN RECOMMENDS A LEVEL OF 50 as a minimum.

Please check with your doctor and ask about this blood test and supplementation if you are low.
