Optimum Vitamin D Blood Level For Reducing Major Medical Risks In Older Adults

They would not know "optimum" if it bit them in the face.

In testing older patients' blood vitamin D levels, there's uncertainty about where the dividing line falls between enough and not enough. The threshold amount has become controversial as several scientific societies set different targets.

To help resolve this debate, University of Washington researchers conducted an observational study. They wanted to learn how much vitamin D must be circulating in the blood to lower the risk of a major medical event. This category included heart attack, hip fracture, diagnosis of cancer, or death.

Optimum is a lagging indicator.

It is always after the fact.

This article, like so many about the cure du jour, is bulls**t.

And so is the research upon which it claims to be based.
