I was put on 5000IU D2 and I got kidney stones, twice. The doctor wouldn't believe that the D2 was the cause, but I stopped taking it and the stones have not recurred.

I would like to bring my D levels up, but not at the expense of kidney stones.

I was put on it because I have stones and my parathyroid hormone level is 2.5x normals. The understanding is that low vitamin D causes higher PTH which can influence stones even though my blood calcium is normal. We didn't get to a root cause on the palpitations but my vitamin D has dropped back to 9 so I am going to have to supplement.

Why D2?
