As per ray2502, with TMAU, people have reported a fishy odour however no above symptoms were reported such as the clearing of
throats and difficulty breathing etc. It is more of
an odor problem.
those with PATM and an odour, that odor could be from the sulfur component in our body which has a pungent odorous smell.
Anyways to continue on…with my research so far, I keep coming back to disorders of digestion as the cause.
