From the Vitamin D council website:-
"When researchers went to an Italian nursing home, they found that 99 of 104 residents had no detectable vitamin D in their blood,"

Bad news for these people ?

All of the 104 resident were over 98 years old!

I hate to think what would have happened if they'd been keeping their vitamin D levels 'normal'.

"High vitamin D intake is associated with brain lesions in elderly subjects, possibly as a result of vascular calcification (Payne et al., 2007). Genetically modified mice with high vitamin D levels show signs of premature aging: retarded growth, osteoporosis, atherosclerosis, ectopic calcification, immunological deficiency, skin and general organ atrophy, hypogonadism, and short lifespan (Tuohimaa, 2009). Vitamin D supplementation during infancy is associated with asthma and allergic conditions in adulthood (Hyppönen et al., 2004)"
