High doses of Vitamin D prevent fractures in oldsters

I know, I know, it's getting boring.  Here's a study, summarized by Medline Plus (Natl Library of Medicine), showing that in older people, doses above 800 IU are necessary to get a reduction in hip fractures.  So, all that conservatism in the IOM study is missing out on the fact that oldsters such as us may need a whole lot more vitamin D than they suggest.
