I have been dealing with IBS for over 25 years - severe constipation, bloating, gas and general overall tiredness. I tried a number of things, multiple endoscopies and colonoscopies, eventually I found out that I had SIBO with methane predominance. That’s when I started looking into ways to kill the methanogens in my small intestine. After trying a number of products I finally found some relief with FixBiome. My symptoms improved drastically (although they have not completely disappeared even after 8 months of using the product, but I have been suffering for over 25 years). I would never have a well formed stool, now my stool is well formed and I have much more energy and much less brain fog. Highly recommend this product.
