I am wondering if anyone might understand the relationship, or assumed relationship, between a very low Vit. D blood serum reading (13) and the development of kidney stones? I have had 6 calcium stones in the past three years (2 passed, 2 litho'd, two still in place) I know that Vit D is crucial for calcium absorption, could it be that with the low D the calcium was not being absorbed but rather deposited in the kidney? I also just found out I am allergic to cows milk and have suspended all dairy. My doc now has me on 3000 IU of Vit D a day now...
I am just confused about how all this might affect the dev. of stones..or not? Any clues???

Calcium in and of itself actually stops stones from forming. It is the antioxidants (or oxolate) that binds with calcium to form stones. Vitamin D comes mostly from dairy products so if you decreased your calcium intake, your D would be depleted.

I also have a low vit D level, and was put on 50,000 IU of vit D a week (take it at the beginning of each week). I also make kidney stones (calcium oxalate) like it is my job. I don't really know of any relationship between the two. My doctor at Mayo didn't mention a relationship. Hope you can get to the bottom of it!!
