This is kind of a silly thing to be worried about with Vitamin D. Yes it's fat soluble. But the amount you would need to take in supplements to cause a problem is enormous. (Every vitamin is different) You could probably take an entire bottle and you'd be fine. The patients in this study were being given 10x the RDA, about 20k IU/day. You can very very easily get 25k IU out in the sun and your body has no issues. It's safe to take 2000IU/day and make sure to get sun if possible.
