Vitamin D: Adequate Levels Are A Matter of Life And Death
Vitamin D may be the most important single nutrient for longevity. Vitamin D deficiency is linked to the development of numerous diseases that can kill you, including diabetes, cancer, and osteoporosis. There is abundant evidence that vitamin D deficiency is widespread across most demographics, and that a low vitamin D level may affect as much as 90 percent of the world’s population.

A new analysis in the American Journal of Clinical Nutrition looked at death rates in over 62,000 individuals and related them to vitamin D levels. Researchers created a “highest compared to lowest” analysis and found that people with the lowest vitamin D levels had the greatest risk of mortality, whereas those with the highest had much greater longevity. Optimal vitamin D levels for a longer life span were above 50 ng/ml.

Other studies report similar findings and not only is vitamin D deficiency linked to greater death and disease risk, but once you have a disease, low D can accelerate mortality. A recent study in the journal Critical Care found that in people who were admitted to the hospital due to disease complications, over 75 percent were deficient in vitamin D. Those people then had a much greater risk of mortality in the hospital. Of survivors who were admitted to the hospital, the average vitamin D level was 28 ng/ml, whereas for non-survivors it was 9.7 ng/ml, which is abysmally low.

An easy way to begin to increase your vitamin D level is to take a high-quality vitamin D supplement of at least 5,000 IUs a day. The Vitamin D Council and most alternative medical practitioners suggest a level of at least 50 ng/ml for optimal health and longevity.
