blood test for vitamin D question

[Lida]

Hi Vickie and her2 friends,
My vit d. level was at 24, though I was taking over 1000 of d3 supplements per day. My prim. doc recommended taking weekly 50,000 iu d2 for 8 wks and then rechecking. I am on a pretty tough regimen now of Herceptin/Taxatere/Carboplatin and am concerned about additional side effects from the large dose of vitd. An onc I had in the past said this combo (with the vid d) could increase my side effects such as nausea. My nutritional onc. dr. suggested taking 4000 iu per day of d-3 instead. Vickie and any of you on chemo and high dose vit d, do you find increased side effects from the vit d? Any other friends had any side effects from high dose vit d? Thank you so much. Lida
