Hey guys,
I've spent countless hours on this forum and learned a ton of invaluable information, but this is my first post. The gut microbiome is an area that is more in my wheelhouse than anything else, as I have been dealing with severe dysbiosis for several years, and it wasn't until a protracted course of abx a couple months ago that I started to experience serious CFS symptoms for the first time. Lots of subsequent research led me to the conclusion that it is an imbalance in the lactate-producing/lactate-utilizing bacteria that is largely responsible for these symptoms. Butyrate plays a role in all of this, so I felt like this thread was a good outlet to share some of what I've learned.
First off, I should say that I have taken CB, and have found it to be incredibly helpful for relieving my brain fog related issues. For my situation, though, I have reason to believe this may be more related to Butyrate's inhibitory effect on the lipopolysaccharide signaling pathways than anything else. Nevertheless, Butyrate does seem to possess an incredible array of beneficial properties with relevance to CFS.
However, CB is not, in my opinion, the best option for boosting Butyrate. The problem is that CB, rather than lowering lactate as has been claimed on this thread, actually
produces lactate, along with acetate and tons of H2 (
see here). This is not necessarily problematic, but I believe what we really want are bacteria that convert lactate (especially D-Lactate) to Butyrate. Such bacteria are normally present in the colon, and most of them belong to Clostridia Cluster XIVa (see
here and
here). Butyrate-producing species from Cluster XIVa far outnumber those from other clusters, meaning that if you are deficient in Butyrate, it is likely these species that you are missing. CB is a member of Cluster I, not Cluster XIVa.
There are some other general metabolic differences between CB and other BPB (CB, for example, is amylolytic, and, interestingly, is a glutton for pectin), but the bottom line is that it seems it's the Cluster XIVa bacteria that we really want. There don't seem to be any commercial options for this at the moment (short of an FMT, which I'm tentatively pursuing), but I'm gonna keep my eyes peeled.
