Nitric Oxide: Supporting Vascular Health, Performance, and the Oral Microbiome with Dr. Nathan Bryan: Dr. Ronald Hoffman interviews nitric oxide researcher and entrepreneur Dr. Nathan Bryan about nitric oxide (NO) as a short-lived signaling gas that dilates blood vessels, reduces inflammation, mobilizes stem cells, supports mitochondria, and is linked to longevity. Bryan explains two NO production pathways: nitric oxide synthase from L-arginine and an entero-salivary nitrate pathway requiring dietary nitrate, specific oral bacteria, and stomach acid; he says sugar-heavy diets, fluoride toothpaste, antiseptic mouthwash, and proton pump inhibitors inhibit NO. Symptoms of deficiency include erectile dysfunction, rising blood pressure, metabolic disease/diabetes, exercise intolerance, and dementia/Alzheimer’s. They discuss limitations of many beet products, Bryan’s N-101 lozenges and NOBeats powder that generate NO, topical NO for wound healing and skincare, a fluoride-free prebiotic toothpaste, an upcoming mouth rinse, potential benefits for resistant hypertension, insulin resistance, cognition, and eye conditions like glaucoma, and access/discount details via hoffmannno.com.
