I've been taking Spring Valley brand taurine supplements (1000mg). I'm not sure how good they are, since my pain is still just as severe as always (newly diagnosed; my pain started during Nov '19). I also take 250mg magnesium and 200mg turmeric (because I misread the label and thought it was taurine, but I don't like to waste things...) to try to help manage the pain, with no benefit.
