On this episode of The Dhru Purohit Show, Dhru sits down with Dr. Nathan S. Bryan to explore why nitric oxide may be the most overlooked molecule in modern health. With nearly 700,000 people losing their lives to cardiovascular disease each year—and half showing no prior symptoms—Dr. Bryan explains how low nitric oxide levels silently set the stage for heart attacks, strokes, metabolic issues, and declining resilience long before a crisis appears.
As one of the world’s leading experts in nitric oxide biochemistry, Dr. Bryan brings more than 20 years of research, dozens of patents, and multiple clinical breakthroughs to this conversation. He breaks down what nitric oxide is, how it’s produced, and what happens when the body can’t make enough of it. Listeners of The Dhru Purohit Show learn how nitric oxide controls vasodilation, blood flow, oxygen delivery, and cellular energy—making it a key factor in both immediate performance and long-term disease prevention.
The discussion covers how nitric oxide is made through two pathways, why oral microbiome health matters, and how everyday habits—like mouthwash, poor breathing patterns, proton pump inhibitors, lack of sunlight, and certain foods—shut down nitric oxide production. Dhru and Dr. Bryan also walk through the early warning signs of low nitric oxide, why high blood pressure often signals a deeper deficiency, and how simple approaches such as nasal breathing, morning sunlight, leafy greens, and targeted supplements can restore nitric oxide naturally.
Listeners also gain insight into new testing tools, future nitric-oxide-based therapies, and the innovation happening inside Dr. Bryan’s company, Nitric Oxide Innovations, which is developing prescription technologies aimed at restoring nitric oxide in clinical settings. The result is a clear, practical, and science-driven conversation that shows why nitric oxide may be the key to better cardiovascular health, stronger daily performance, and long-lasting vitality.
