I was not on dialysis when I started taking Kidney Stuff, but had Creatinine numbers around 3.7. In a few months I had numbers of 1.3 to 1.8 range and it has remained there for going on two years. My family doctor suggested it. My kidney doc said (when I asked permission to try it)it wouldn't hurt me "but it won't help". But it did. I don't know if you can take it, or if it would help you (being on dialysis) but it might be worth an ask. (It is basically purified, cold milled flaxseed) Wishing you the best.
