Episode notes
Sulforaphane Hits Multiple Inflammatory Hubs
- Sulforaphane also directly modulates NF-kappa B and other inflammatory hubs, producing synergistic anti-inflammatory effects.
- John explains covalent modification of regulatory molecules gives sulforaphane broader reach than compounds like curcumin alone.
Choose Stabilized Sulforaphane Not Precursors
- Use stabilized sulforaphane rather than glucoraphanin precursors because conversion in the gut is unreliable.
- David warns most market products list glucoraphanin; Mara Labs and one other actually deliver stable sulforaphane per capsule.
Microplastics Jam Lysosomes And Spread Damage
- Microplastics accumulate in phagocytic cells (macrophages, microglia) and lymphoid tissues, filling lysosomes and disrupting cellular clearance.
- John explains blocked lysosomes change pH, impair protein degradation, redirect cargo into exosomes, and spread dysfunction to neighboring cells.
