“In view of our findings and the existing literature of adverse effects of vitamin D deficiency, there exists now an urgent need for effective strategies to improve vitamin D status in older institutionalized patients.”
These are not my words, but I would add a more urgent need exists for non-institutionalized people, especially young people.
The quote above are the words of Dr. Sefan Pitz and nine colleagues from Austria and Germany who studied 95 nursing homes in Austria, obtaining vitamin D levels on 961 participants. Their average age was 83 and their average vitamin D level was a remarkable 7 ng/ml, although 7% had levels above 20 ng/ml. They drew the blood in 2002, so the authors could go back through the charts and see who later died and compare that to their 2002 vitamin D levels.
