Vitamin D Status Predicts Physical Performance and Its Decline in Older Persons
First, before I go on, these are 4 articles from 4 entirely separate journals published in the same month. If the average doctor is NOT concerned about vit D status in his or her patients, they have to be going out of their way to avoid current medical literature.That being said, we again see that, in this population of patients 65 years of age and older, that serum levels < 20 ng / ml were present in more than half the patients
in this study (ideally, we want to be above 100 nmol / L or 40 ng / ml).The bottom line is that the higher the serum levels, the better the patients performed on physical performance tests.
