Tim, I know you know since we talked about in email (check out the study I sent you), but some people do worse with supplemental D. Some suppose that the body cannot metabolize supplemental D in excess, especially if there exists an endocrine disorder of some kind. Perhaps with sunlight, this is not an issue.
You're right, though, D is a hormone and a secosteroid. Maybe because of these reasons, it can help some, but not all people with spine problems. I am just glad to see that some spine docs are screening patients for parathyroid and D metabolites as part of the screening process. Better to find any bone growth issues BEFORE surgery, eh?!
OK, sorry for the hijacking.
