sans why did you think you had low stomach acid in the first place (I forget if you told me) was it acid reflux or something else? bitters have not worked for me for some reason I use to use them when I wasn't having acid reflux and they were fine to take but now that I'm having bad acid reflux there not doing a darn thing..neithers anything but ACV is helping get through one meal, still very painful but better than without... the problem with ACV is that its not a solution, so hopefully when I kill off more candida the acid reflux will go away.
