HCL supplements

For those of you who take HCL supplements, does it help with your UC? Obviously it helps to give the stomach more HCL to break things down, but I am wondering if it helps UC at all? I could imagine that maybe if the stomach destroys pathogens with optimal HCL, it can help downstream with UC but not sure.

ok the reason i ask is that I have above 90 MCV and some people in the medical community believe that this, combined with the fact that I have UC, is an indication that I have low HCL.
