HPHPA and dopamine/norepinephrine imbalance

[dishealthful]

I recently did and Organic Acids Test (OAT) which showed high levels of HPHPA (3-(3-hydroxyphenyl)-3-hydroxypropionic acid), which is a metabolite that blocks the activity of DBH and subsequently reduces the conversion of dopamine to norepinephrine. I also have direct markers of a high dopamine:norepinephrine ratio

I'm not sure how legitimate the OAT is, but many of my neurological symptoms could be explained by such a neurotransmitter imbalance.

I'm wondering if anyone has experience with OAT results, or if anyone has any ideas on what I could take to break down HPHPA in my gut
