I’ve written before that I am taking Betaine HCL with Pepsin as a digestive support supplement to address low stomach acid. This was recommended to me by my functional medicine doctor, as well as suggested in Aglaee Jacob’s book Digestive Health with Real Food. I believe this supplement is making a real difference in my IBS-D symptoms. I started taking it shortly after starting the elimination diet, and have noticed real improvement over the last couple of weeks.
I want to talk more about the problem that this supplement is meant to address — low stomach acid — and refer you to some good resources to help you decide if trying this supplement is right for you.
