I think low stomach acid could be a big factor in the viscous cycles we get into. HPA axis issues results in poor metabolic rate and poor HCL secretion which allows pathogens etc to grow over. I have gotton some betaine HCL powder and i plan to put it into capsules. But i have just read that its useless without pepsin. Is this true? I am not going to buy pepsin bulk powder too and weigh that crap out lol.
