@ddon true-get our needs from foods, easier for body to process than supplements ! With CKD we do have to take care with everything we ingest…some foods, drinks (especially alcohol) and meds (NSAIDS) can be very hard on kidneys….supplements (they are not tightly regulated) often have things in them that are hard on kidneys…and CT contrast is hard on them as well—techs can give a better contrast and/or give you IV hydration after the CT. There are quite a few things we can do ourselves, including hydrating well.
