Have you turned light stool to dark?

Looking for help on how to fix what I assume are some problems relating to bile.

Stool is never normal brown. Always light brown, cardboard, yellow, etc.

Sometimes ox bile doesn’t even help. I had an ultrasound and it didn’t show any stones or anything, so I don’t think flow of bile is being blocked…

I just don’t know what to try. Have tried TUDCA, ox bile, taurine, glycine, etc. and no success at fixing this…

If there is no stones preventing bile from flowing, what else could be the issue? Lazy gallbladder? Some sort of nerve dysfunction? Microbial imbalance?

My history is salmonella to ulcerative colitis diagnosis… and Lyme long before that. But ever since the antibiotics for salmonella (cipro and others) things have never been the same.

I’m afraid it caused some sort of microbial imbalance or mitochondrial damage.

Ox bile and TUDCA should turn my stool brown (they have before) but not always.

Maybe there’s sludge or the quality of the bile is not ideal. I’m not sure.

What else should I try or have a doctor look for because basic tests never find anything majorly wrong… other than high calprotectin and CRP.
