 The dark leafy greens, your body has an issue with oxalic acid, and that's one of those things. The other thing is check your vitamin D levels. It sounds like your body's not utilizing calcium very well, and when that happens, it means your vitamin D levels are a little bit low. So I would get that checked by blood test, easy to check. And then if you start taking vitamin D at any supplemental level, make sure you're taking vitamin K2 with it because the vitamin K2 makes sure that the D utilizes the calcium in the right way and doesn't create an over-calcification.
