概要
We’ve joked about “poop toothpaste” for years—today we bring data. This episode dives into a new human study using a heat-killed Enterococcus faecalis (EF-2001) toothpaste/paste approach in 137 people with tough oral conditions. About 65% reported better oral symptoms—often within 2–4 weeks—and, notably, ~65% with gut complaints also improved over 4–8 weeks. Those oral gains significantly tracked with GI improvements, hinting at the oral–gut axis in real life. We unpack why non-live, postbiotic strategies (plus gentle prebiotics and contact time) may shift biofilms, cool inflammation, and offer a safer, ecosystem-friendly path than scorched-earth antimicrobials—while acknowledging the study’s open-label limits and the need for blinded RCTs.
