LONGEVITY with Nathalie Niddam #425: Broccoli Power: The Secret Longevity Molecule (Fighting Toxins, Microplastics & Aging) | Sulforaphane Exposed With David Roberts & Dr. John Gildea
16 snips
Mar 31, 2026 Dr. John Gildea, a clinician‑researcher in detox pathways and NRF2 signaling, and David Roberts, researcher and co‑founder who developed a stabilized sulforaphane supplement after personal toxicity experience. They discuss stabilizing sulforaphane, how it influences inflammation and NRF2, microplastics and pollutant mobilization, differences between sulforaphane and glucoraphanin, and practical detox strategies.

Episode notes
Microplastics Distract Immune Cells And Spread Inflammation
- Microplastics concentrate in phagocytic cells (macrophages, microglia), filling lysosomes and altering pH, which impairs protein degradation and immune surveillance.
- Blocked lysosomes shift misfolded proteins into exosomes, spreading inflammatory signals to neighboring cells.
Poop Daily To Help Clear Microplastics
- Prioritize regular bowel movements because feces is the dominant route for microplastic elimination.
- John Gildea: most microplastics appear in feces; ensuring daily clearance helps remove the bulk that isn't absorbed.
N‑of‑1 Saw Microplastic Spike Then Rapid Drop After Sulforaphane
- An independent N-of-1 reported a spike in blood microplastics the day after taking Mara's stabilized sulforaphane, then a rapid drop the following day.
- The researcher observed lysosome dissolution and mobilization, suggesting sulforaphane may mobilize stored microplastics for excretion.
