I purchased CBD with curcumin. Curcumin can contain oxylates which can form kidney stones. I've recently had two of them. I inquired to see if the product I bought contained oxylates and Zatural sent me a chemical breakdown of the product which did not answer my question.
This is a serious health concern and they should know what is in their product. Now I'm stuck with something I purchased that I can't use or return. Not happy.
