Sulphur intolerance could be related to molybdenum defciency , i would try taking it, slowly first and then up the dose .

This could be also related to Glyphosate in foods , it acts with molybdenum in a bad way . Glyphosate is not the only poison they use , so eating only organic would be good.

Body needs suplhur. I think something is wrong in our current enviroment, that so many seems to get Sulphur intolerance, i suspect toxins,heavy metals , and those can antagonise molybdenum which is needed for proper sulphur metabolism .
For gut inflammation, curcumine can help ( Solgar Full Spectrum Curcumin ) and if the reason for inflammation is caused by heavy metals , high dosage zinc, selenium and alpha lipoic acid help flush /bind heavy metals down . For herbicide toxins like Glyphosate need activated charcoal, clay or glutathione supplement which is sulphur based , so maybe use that later if get the sulphur issue solveld. Is the inflammation is caused by bacterias, wrong kind of bacteria in wrong place as if in SIBO i might suggest taking lots of natural antimicrobials and aftef that alot good probiotics, the anxiety might be becouse of gut microbiome issues which also would require a lot probiotics. Magnesium, zinc ,vitamin b 12 , all B-vitamins are important and could help with anxiety ; anxiety can be also just becouse gut dysbiosis produces toxins that effect the gut-brain connetion, and also directly by entering blood if have leaky gut, by taking activated charcoal 2-3 times a day might give some clue , i mean if you feel better taking it , it means you have toxins in your gut that have direct effect to your mood.
There seems to be general problem of not having bitters, which our intestines need . Bitters have changed to sweet taste which is bad. I think people should use Swedish Bitters , it`s wonderfull for body and specially for digestive system . Sugar is bad and dangerous to body.
