Usually taking anything that boosts dopamine substantially is a bad idea considering most AP’s work to block dopamine. If you were to try something for more dopamine I would go with curcumin/turmeric which is a mild agonist of dopamine.
i have not tried tyrosine and i agree with Mr_Hope that increasing dopamine will worsen psychosis. try talking with your pdoc about changing your antipsychotic to lurasidone it works great for me and gives me good motivation and stable mood. if this didnt work you can drink coffee it increases dopamine if this didnt work you can take Bupropion or Sertraline they both increase dopamine but there is possibility you worsen your psychosis and you better discuss this issue with your psychiatric doctor before taking them.
