Host Morgan of the Primal Kitchen Podcast welcomes Dr. Nathan S. Bryan—biochemist, entrepreneur, and nitric-oxide (NO) researcher—for a fast primer on why NO is a foundational signaling molecule for vascular function, metabolism, immunity, cognition, and sexual performance. Dr. Bryan explains the two main NO pathways (endothelial NOS enzyme and the oral-microbiome nitrate→nitrite route) and why production declines with age. He argues that restoring NO can normalize blood pressure, support insulin signaling and glucose uptake, enhance exercise tolerance and sexual function, and improve tissue oxygenation.
He outlines his product ecosystem: a once-daily NO lozenge (orally disintegrating tablet that releases NO gas), a fermented beet powder (designed to avoid oxalates and typical beet taste), and topical NO skincare (with clinical trials showing improved hydration, collagen, and fine lines). He also discusses ongoing drug programs targeting ischemic heart disease, Alzheimer’s/vascular cognitive impairment, and diabetic ulcers.
Practical takeaways: stop habits that may blunt NO production (antiseptic mouthwash, fluoride products/water, and PPIs/acid suppressors), then stack positives—balanced diet, micronutrient repletion (vitamin D3/K2, magnesium, selenium, chromium), daily movement/strength work, sunlight, infrared sauna, intermittent fasting, and (for some) hyperbaric oxygen. Dr. Bryan shares personal notes (decades illness-free, vascular age metrics) and directs listeners to drnathansbryan.com and n1o1.com for education and solutions.
