Dr. Nathan Bryan, Ph.D. is an international leader in molecular medicine and a pioneer in nitric oxide research. He’s the founder of Bryan Therapeutics, Nitric Oxide Innovations LLC, Pneuma Nitric Oxide (now N1o1.com), and Bryan Nitriceuticals (No2u.com). Dr. Bryan was the first to describe nitrite and nitrate as indispensable nutrients for optimal cardiovascular health, and the first to demonstrate an endocrine function of nitric oxide via S-nitrosoglutathione and inorganic nitrite. His nitric oxide technology is validated in six published clinical trials, and he has authored or edited six books alongside publishing highly cited scientific papers.
In this episode of The Dr. K Show, Dr. Bryan explains why nitric oxide—an ultra-short-lived gas—became so important it reshaped modern cell signaling and vascular biology. You’ll learn how nitric oxide supports blood vessel dilation, oxygen delivery, mitochondrial function, inflammation control, immune regulation, and even stem-cell mobilization for repair. He also breaks down a practical “symptom hierarchy” that can signal declining nitric oxide production: sexual dysfunction, rising blood pressure, insulin resistance, exercise intolerance, and cognitive decline—framing Alzheimer’s as a vascular-metabolic condition tied to chronic low nitric oxide.
You’ll also hear a compelling discussion on why modern lifestyle factors can sabotage nitric oxide pathways—high-sugar diets, antiseptic mouthwash, fluoride exposure, and acid-blocking medications—and what to do instead (nutrition, movement, fasting/autophagy, and sunlight). For those who want to go deeper, Dr. Bryan shares where to find his work and technology at N1o1.com, No2u.com, and on Amazon, along with his book The Secret of Nitric Oxide: Bringing the Science to Life.
