Episode Synopsis

Your body processes acetaminophen via two distinct pathways:Phase 2 metabolism (the safe route): ​Your liver adds molecules through glucuronidation and sulfation - making it water-soluble so you can pee it out safely.​Phase 1 metabolism (the toxic route): ​Your body tries to "burn" the acetaminophen through cytochrome P450 oxidation... creating NAPQI - a highly reactive molecule that depletes glutathione (your master antioxidant) and damages mitochondria.PMID links Cord blood study: Mothers divided into 3 groups by acetaminophen levels at birth. They found a 4x increased risk of Autism with higher exposure. (PMID: 31664451)​Animal study (2014): Two doses before day 10 caused permanent brain changes; males more affected. (PMID: 24361869)​Neuronal death: Even non-lethal doses kill brain cells in developing animals. (PMID: 21170329)​Systematic review (2025): 46 studies - the stronger the study design, the stronger the association. (PMID: 40804730) What about the studies "DEBUNKING" it?!”​​Those studies are incredibly misleading….Let’s consider the biggest one, which followed 2.5 million Swedish births. ​They compared siblings - one exposed in utero, one not. When they did this, the autism association disappeared. (PMID: 38592388)​
