Methylation, MTHFR & Why Your Body Can't Detox, Balance Hormones or Make Serotonin Without It

takeaways

1. Dr Jean-Marc Sobczyk explains that methylation involves a 'methyl group' acting like a stamp needed for biochemical reactions including detoxification, hormone metabolism and balancing neurotransmitters like dopamine and serotonin.

2. Having an MTHFR or other methylation variant is described as a state of metabolism rather than a disease, and many people with variants function very well, though it may matter more during pregnancy, high stress, growth or intense training.

3. Gut health is framed as foundational, with the discussion noting around 70% of serotonin and dopamine is produced in the gut, and that treating the gut can coincide with improved mental health.

4. Leaky gut (increased intestinal permeability) and SIBO are discussed, including testing via stool tests, zonulin markers, endoscopy and breath tests, and why probiotics may not be the first step.

5. Longevity tools discussed include wearables, HRV, sleep and glucose trackers, and biological age tests such as GrimAge and Dunedin Pace of Aging, which relate back to DNA methylation.

6. The foundational habits highlighted were sleep (7-8 hours with deep sleep), regular exercise mixing weights and endurance, a Mediterranean-style whole-food diet, and real-life social connection.
