A quote which touches upon what I was talking about with probiotics.
" Probiotics are actually a mixed bag with SIBO because SIBO often involves an overgrowth of D-lactate-producing probiotic species, and that causes a buildup of D-lactate in the gut, and a lot of the symptoms associated with SIBO are caused by that. So, you want to avoid in many cases taking any probiotics that have D-lactate-forming species like Lactobacillus acidophilus, which is, of course, one of the most common probiotics that people take. There’s a D-lactate-free product sold by Custom Probiotics that’s helpful. ".
