I have same problem but I am trying out Cal/Magnesium/Zn combo right now. I have clean vegan diet monstly raw, no gluten, and have used all types of supplements as well. Tried probiotics all forms, Chinese herbs/Mushrooms from this board years back, HCL tabs, chlorophyllin, juicing, fasting, enemas, cleanses, etc etc etc.
I am SO sick of not finding the answer. The diet I have now helps to a small degree as well as other parts of a regime. I stay away from choline because I may have TMAU as well. Anyone want to try his suggestion? I will report back on the Cal/Magnesium/Zn combo.
