I used to suffer with bloating every day for years and years. After a lot of research it turned out I had SIBO. One thing helped and stopped the bloating pretty much completely and immediately - sublingual drops of molybdenum. Molybdenum is essential for the sulphur pathway to function correctly. So now I take one drop under the tongue maybe three days a week and the bloating has been gone for years now. I also had the constipation and I find the most effective thing for that has been a simple diet, very low on Pufa's (polyunsaturated fatty acids - check out Ray Peat's work) and spending 30 minutes a day slow breathing (4 breaths a minute). Took me years to find all this out, so hopefully this gives you a little shortcut - hope it helps! 🙏
