If you are pre-op, you can also absorb the cheaper vitamin d that is in oil. If you have any of that around, use it up and save the dry stuff as it's more expensive. There is high dose vitamin D (50k) available in prescription but it's in oil, meaning it could be covered by insurance because it RX (every little bit helps) and would work for you till surgery.
I don't really pay attention to my calcium level, but instead watch PTH, and don't let that get too high, since that can mean I'm taking calcium out of my bones to keep my calcium level stable.
