Thanks to commenter Dave, who alerted me to a great vitamin D study and service at GrassrootsHealth.
It's called D Action, and for $30 you can get a your vitamin D levels checked. You can do it once, participate for a year for two tests, or every six months for five years.
So did I and my level is 67 on 5,000iu per day. Yay!!!
I'm tempted to nudge the dose up a bit as I've had a continuing bout with a bug for a month now. What do you think?
Hi Richard –
I got my kit in the other day. I posted some pics if you are interested:

Thanks for your blogging on this topic – you certainly opened my eyes to the importance of vitamin d.
I'd say that's your personal choice. You might up it to 6K (mine and my wife's daily dose), or stay the same and see where you are in six months. If this is your first test, then you don't know what you were at before you began supplementation, and you may still be on the way up to some sustained level.
In any case, getting all the way up to 80 is probably a good target.
Very cool. Even though the test would probably be covered by my health plan (my wife's was tested as a matter of routine a few months back — 30ish — and now she on the sups too), it's highly worth $30 to not have to leave the house to do it, and plus, it seems to be partially funding a good cause, i.e., the data and epidemiology that can be learned.
