Anyone from this old thread still interested? Have you done any experimenting with Vit D since then? It's certainly in the media these days as it appears the medical establishment has woken up to what alt med knew years before.
I've been upping my intake as the years go by and may up it even more this year. I went from 2000 to 4000 IU to 7200 last winter. I don't get that much sun in the summer either, so I think I will start taking 4 of the 2400 IU capsules I have, possibly more and then have it tested myself.
Through Life Extension, for nonmembers, it's $68. Still pricey as far as I'm concerned but much less than going to a doc.
There is also a home blood spot test available through ZRT labs and some alt med websites. That would be better yet, but costs $130.

Last winter when I took the extra Vit D and also Vit C (Emergen-C) was the first time in years I have not gotten sick.
From the Vit D Council,
"Heaney's recent research indicates that healthy humans utilize about 4,000 units of vitamin D a day (from all sources). Heaney R, Davies K, Chen T, Holick M, Barger-Lux MJHuman serum 25 hydroxycholecalciferol response to extended oral dosing with cholecalciferol.Am J Clin Nutr. 2003;77:20410 However, 40,000 units a day will hurt them (over several years). Vieth RVitamin D supplementation, 25-hydroxyvitamin D concentration, and safety.Am J Clin Nutr. 1999;69:84256 Therefore, vitamin D has a therapeutic index of 10 (40,000/4,000), twice as safe as water. Although we are not saying it is as safe as water, we are saying vitamin D is safe when used in the doses nature uses." http://www.vitamindcouncil.org/vitaminDToxicity.shtml
