Many listeners feel wired but tired, foggy, or stuck on low energy despite healthy habits. This episode decodes the methylation pathway — the biochemical highway that uses B-vitamins to make neurotransmitters, clear hormones, and detoxify the body — so you can stop guessing and start tailoring nutrition, supplements, and routines to your genes. Elena frames the clinical, naturopathic implications in plain language; Jax breaks down common variants (MTHFR, COMT, BHMT, MTRR), what they mean for folate and B12 needs, caffeine sensitivity, and homocysteine risk. Our guest is a clinician-scientist who treats methylation-driven fatigue and mood disorders; together we translate genotype into safe, doable swaps: the right folate form, timing caffeine around COMT status, measured SAMe or methyl-donor strategies, and simple lifestyle support for methylation resilience. Listeners walk away with a clear action plan and an invitation to submit de-identified snippets for future genome breakdowns.
