This supplement works amazingly. Somewhat expensive though. Still worth it for sanity!
As for diet though, I’d say a high carb / low fat / low protein diet would stop tryptophan from being converted to kynurenic acid, the main culprit behind schizophrenic symptoms.
It barely matters for me at this point though, since even if I cheat and eat high fat / high protein foods, I don’t get psychotic flareups anymore, thanks to Amyloban 3399.
