Hi David,Just be mindful of some of the vegetables and the absorption of oxalates. As we want to maintain the oxalate levels low.When you are in stage 2, all we can do with some supplement is try to maintain the health of the kidneys. But if I was in your shoes, I would not settle for maintenance, I would want to explorer and test other options to fix the issue and revive the damages. So, That said, your possible best option, is either stem cells or peptides. I would try to peptides first, and find out if this is something you can get you in your country or not. Look for Atrial Natriuretic Peptide.If you are going to try this peptide, make sure the doctor does know how it works and how much intake is required, as it does increase urine to restore pressure back of the kidneys.
