So when I suggested the 5000iu a day, I did not know what your present level is. The VDC usually recommends maintaining a level of 50ng/ml. At levels below 40ng/ml your risk for cancer and autoimmune illness increases dramatically. So your present level is acceptable. Here are several things to think about. If your level of 44ng/ml is a mix of “sunshine” and the 2000iu but if you live somewhere (latitude) that you cannot make much if any in the winter, then you may have to increase how much supplement you take in the winter. You could probably take 3000iu and that should put you just a little over 50ng/ml. Now if that 44ng/ml contains no “sunshine” and is just with the 2000iu, then you are probably someone that gets a higher level on a smaller amount of Vitamin D. If that is the case, then you may want to stay with the 2000iu a day.
As for the multi with no calcium, I doubt it exists. I would think the amount in a regular multi isn’t too high and therefore would not be an issue to take. You will have to decide though, what you want to do.
