blood test for vitamin D question

[Linda]

My onc has been testing Vit D levels for some time. She believes that women who've had bc should be on the high end of normal, and most of us are low. I took supplements for a while and ended up having to take 7000 units a day to get my levels where she wanted them (last level was 66.) We continue to test because she believes that too high a level can be damaging. I think the top level would be in the 80's or so (I'm sure someone else will know.)
I'm happy to keep taking the supplements. They're (d3) easy to take, cheap and I have no adverse effects. I actually think I'm not getting colds and flus when everybody around me is sick.

Got my result today from last weeks blood test for Vit. D level. This is AFTER the 8 week megadose of 1 50,000iu cap per week.

Number is up to 50 - wow, the BIG 5-0.

Up from 30 pre-megadose.

So now Shadowpilot has me wondering if I need to really do more than the 4,000 iu/day I was planning???
(Since we share the same climate and can't always drop whatever we are doing and run outside when the sun does decide to shine!)

I was figuring on trying to hold around the level of 50.

Will see my med onc in a couple of weeks so will decide with her, since my general doc is only recommending the standard 1,500 iu supplement per day.
