Viome does a similar analysis of what your microbiome constituents can do, and it provides recommendations of supplements and dietary changes to modify the composition of one's microbiome. I've done it twice and found it quite helpful.
I look through the sample report for the Microba test And I see it does a nice job of saying what your microbiome constituents can do, As well as helpfully giving percentages of how many of what or found in your sample, but I don't see anything in the report, maybe I missed it, that tells you what to do about it. And the devil's in the details on that one.
Ive done GI Effects, GI Map and CDSA, I might each have their pluses and minuses, just as Microba and Viome do. I think They are helpful if you want to know if you have anti-gliadin antibodies, malabsorption of fat, or parasites or fungi, and they're pretty good with point solutions to address the bad things it finds, but I don't find them very good at suggesting what to do to improve the overall composition of the microbiome like Viome did.
Viome suggested lactobacillus plantarum, which I had not heard of before, which got rid of my gas within a week. Another time it suggested Iberogast, a herbal preparation from Germany, again which vastly improved my gas and bloating symptoms pretty quickly. It gave suggestions of certain products each time, but invariably I had allergies to some ingredient in them, but I was pretty easily able to find other versions with the same ingredients that I wasn't allergic to, and I was able to take them.
Your last find leads you to cfsremission.com and related sites. The guy behind it's premise that all ME/CFS can be cured by fixing the microbiome is a little less than honest, and he knows it, and his algorithm suggested that I eat Roundup and high maize starch when I'm allergic to corn, So I found it utterly useless, and I really didn't find knowing every single species that I had living inside me to be useful either. It totally missed my oxalate problem which Viome and Microba would flag.
The goal is to improve one's microbiome to function better and improve one's health. None of these tests are perfect, And it seems to me that once you Get rid of any parasites or fungi and biofilms, the game is to improve microbiome composition, which is best done by manipulating foods, and avoiding drugs and toxins that kill off various species. And, since none of the tests provide adequate information to solve all of your problems, it makes sense to do different tests over time, with a hope of having a better overall outcome. But, nobody knows what a perfect microbiome composition is, so it's all guessing at this point.
@junkcrap50 do you know if Microba can be ordered from the US, if it needs a doctor to order it, and the cost?
