395 — Dr. Nathan Bryan: Hormones, Heart & Skin—Surprising Roles for Nitric Oxide

Author: Doctor Podcast Network October 2, 2025 Duration: 1:14:00

Molecular-medicine expert Dr. Nathan Bryan explains how nitric oxide (NO) protects the endothelium, drives vasodilation, and influences energy, immunity, hormones, and longevity. He links stubborn hypertension and poor exercise tolerance to the microbiome–NO axis and outlines common NO killers—antiseptic mouthwashes and fluoride overuse, chronic PPIs, ultra-processed diets, and inactivity. We cover practical restores (movement, nutrient-dense food, targeted micronutrients, careful PPI weaning, ditching antiseptic rinses) and preview clinical work on NO-releasing lozenges for ischemic heart disease, approaches to improve cerebral blood flow and insulin signaling in cognitive decline, and topical NO for chronic wounds. Bryan also touches on food quality (glyphosate, soil health), hormone synergy with NO, and NO-based skincare that supports perfusion and collagen. Bottom line: rebuild NO, and the body’s own repair systems can finally do their job.
