Bipolar presents with episodic mood shifts—depression and mania/hypomania marked by reduced need for sleep, elevated or irritable mood, rapid speech, and risk-taking—separate from day-to-day triggers. Alongside standard care (mood stabilizers, atypical antipsychotics, circadian and stress routines, CBT/IPSRT), we review Walsh-style biotypes and nutrient factors that can shape resilience: methylation status (whole-blood histamine, homocysteine or SAM/SAH), copper/zinc balance (Zn/Cu with ceruloplasmin), glutathione/redox tone, vitamin D, and RBC magnesium. Nutrition emphasizes protein-first meals, low-fructose whole foods, magnesium- and potassium-rich plants, sulfur-supportive vegetables (as tolerated), and strict sleep regularity (light timing). Posts compile practical routines, lab literacy, and clinician videos to help patients and families navigate episodes and maintenance.
