Toxicity and vitamins
I think we talked about this? Some labs use a 50-150 range for the D, 25 hydroxy test. 150 is not too high.
For water soluble dry vitamin D, a high level doesn't mean toxic. It means high. You would have to reach 750 (!) for any signs of problems arise.
D2 is a different matter., Pretend we could absorb more than a fraction of an IU, if you chugged a bottle a day, you could go toxic. If you were intact. Since we don't absorb the oil form, or the D2 form, that's kind of a moot question. Who could afford to eat enough of them to reach any kind of danger zone.
Although I'm kinda late here, you may end up with 1/day and an extra 2-3 per week. I find that bulky, so if me, i'd probably do a week of 1/day, next week 2/day, and so forth. My endo wants me at 50, his lab uses 20-50 range, which takes in the "Way Back Machine" to the late 90's. Not happening. He's never heard of the Vitamin D Council, so he's using his past textbook info, not any current data.
Let us say I was speaking to family members, people I love lots, and their medicals told them to STOP their D supps? NO WAY. Then it plunges back down into single digits and it may NEVER come back again. Take fewer to humor those who run your labs, but don't do anything crazy.
And be sure the test run was D, 25 hydroxy. The D, 1, 25 dihydroxy is not a good indicator of resident vit D. It is more like taking a snap shot of what your wore to the lab that day. It could be drastically high or low in a 72 hour period.

P.S. My year + long absence has NOTHING to do with my WLS, or my type of WLS. See my profile.
