I'm going to add another voice to the negative views on supplemental enzymes. I recently began taking a potent enzyme formulation and ever since then I've been having a lot of gurgling in my gut, along with flatulence and a bit of diarrhea. I don't know why i bought them in the first place, other than "compulsive supplement shopping syndrome," and the reason I am still taking them is "fear of letting something I bought go to waste." But now that I've seen the comments above, I think I'll stop taking them.
As for probiotics, they're awesome. You might want to do some reading on prebiotics, which are foods that help nurture a healthy intestinal biome, as well as maybe looking into some of the cool recent research showing how certain microbes affect everything from mental health to obesity. We are self-contained ecosystems. Nobody here but me and a few hundred microbial species. Maybe one of them is controlling what I write, and wants to convince you to make life better for its species.
