Picky Eating and Brain Chemistry: Amino Acids, Serotonin and Dopamine in Autism
Why can a short list of safe foods matter for mood, sleep and focus? The hosts follow protein from the plate to the brain: how tryptophan and tyrosine become serotonin and dopamine, why vitamin B6 (P5P) sits at the finishing step, what the tryptophan depletion studies show, and a measure-first approach that starts with a fasting plasma amino acid test.
Correction: at 19:35 the hosts describe lithium orotate as slowing the enzymes that break down dopamine and serotonin. That isn't an established mechanism for low-dose lithium, and human research on lithium orotate is limited. Products named in this episode: MITOboost, SPECTRUM Neurotransmitter Support and Lithium Orotate (ASDHelp sells all three).
