Descripción del Episodio

Fluoride is in 99% of children’s toothpaste… and some studies suggest it may lower IQ by up to 7 points. Parents were never told this. In this episode of Digital Social Hour, Sean sits down with nitric oxide researcher Dr. Nathan Bryan to talk about fluoride, oral microbiome health, brain development, and what this means for children. Dr. Bryan explains: • Why fluoride is classified as a neurotoxin • The study linking fluoride exposure to IQ reduction • How the oral microbiome impacts brain health • Why mouthwash may disrupt nitric oxide production • The difference between topical vs ingested fluoride • What parents should consider when choosing toothpaste This conversation dives into the science behind fluoride exposure and why protecting children’s microbiome health may be more important than we think. If you’re a parent — or plan to be — this episode may completely change how you look at oral care. ⏱️ Timestamps 0:00 – Fluoride & children’s IQ 1:12 – “Fluoride is a neurotoxin” 2:30 – The 7-point IQ discussion 4:05 – Oral microbiome & nitric oxide 6:10 – Mouthwash concerns 8:45 – Fluoride in water vs toothpaste 11:20 – What parents can do 🎙️ APPLY OR CONNECT 👉 Interested in being a guest?
