I am low in BH4 which limits my ability to metabolize amino acids down the common pathway and thinks like phenylalanine get metabolized dow the alternative pathways creating PEA and Tyramine. But also I have the mental illness associated changes in TAAR1 and VMAT1 and VMAT2. (I have schizoaffective Bipolar Disorder.)
this is an amazing amount of self knowledge about these topics - i'm sure some came from introspection, but for the rest - how did you find these things out or are you in the field?
seems like useful knowledge for people to have, aside from problems with over self diagnosis of course
