Yes indeed, that&#x27;s who I used. I didn&#x27;t notice any change after just a month, it took a year; I&#x27;m taking a break at the moment to see if any symptoms resurface. The original article for this thread mentioned that the mouse model the researchers are building indicates that successive generations of mice with weaker biomes did not improve after starting on a heavier-fiber diet (though long-term, who knows if it might start improving). Might there be a possibility that biome damage has a similar pathology, and reconstitution via probiotics takes an especially long time? Nobody knows at this point.<p>GB is not exactly cheap if you are on a student budget, so in the interest of full disclosure and crufty, messy, crowd sourcing pseudo-science, I&#x27;ll offer some caveats of what else I was trying at the same time that might have also yielded my results. I tried two other brands of probiotic before settling on GB: Dr. Ohhira&#x27;s and Bio-K+. Six months on Bio-K+ followed by two months on Dr. Ohhira&#x27;s. At the same time, I went to a 20 mg &#x2F; day maximum net carbohydrate, high-fat, moderate protein diet. I used testing strips to verify that I actually went into ketosis, and cycled to a 100 mg net carbohydrate day once 1-2 months to break weight loss plateaus. So before you &quot;follow in my footsteps&quot; and commit to a year of GB, be aware I had confounding factors that might also explain what happened to me (the ketogenic diet is the next candidate for a cause, but I&#x27;ve never heard of anyone being able to eat spicy foods again by starting that diet).<p>If I had the time and access, I&#x27;d pay to try bacteriotherapy using donor material from an athletic donor who likes spicy food. I suspect bacteriotherapy is good for more than just CDI.<p>The GB guys are super helpful and friendly, and you go month-to-month. I found suspending or cancelling super easy and hassle-free. So if you are curious to partake in your own N=1 experiment on gut microbiome reconstitution for just a month (though they themselves say don&#x27;t count on any changes before within months), I encourage you to try it out and share your results.
