If you care about longevity, brain optimization, sexual performance, or metabolism, this molecule changes everything. Host Dave Asprey sits down with nitric oxide pioneer Dr. Nathan Bryan to reveal why this overlooked molecule controls your blood flow, mitochondrial energy, neuroplasticity, insulin response, and even your libido. You’ll learn how nitric oxide acts as a master switch for human performance and why the medical system has ignored it for decades.

Dr. Nathan Bryan is a world-renowned expert in nitric oxide biochemistry with over 20 years of clinical research, multiple patents, and collaborations with Nobel Prize-winning scientists. His groundbreaking work forms the foundation for modern functional medicine protocols targeting blood flow, metabolism, cognitive enhancement, and mitochondrial upgrades.
You’ll learn:
• How nitric oxide drives mitochondria, metabolism, and human performance
• Why most nitric oxide supplements fail and how to spot real ones
• The critical role nitric oxide plays in brain optimization, libido, and insulin signaling
• How poor oral health, statins, and PPIs can kill nitric oxide production
• What nitric oxide has to do with sleep optimization, aging, and disease prevention
• How to stack nitric oxide with fasting, ketosis, nootropics, red light, and supplements
• Why “Smarter Not Harder” starts with nitric oxide fueled upgrades
This episode is essential listening for anyone into biohacking, cold therapy, functional medicine, or RFK-style medical freedom. You’ll walk away with practical tools to boost nitric oxide naturally, prevent dysfunction, and optimize your biology whether you’re on a carnivore diet or just looking for an edge.
Dave Asprey is a four-time New York Times bestselling author, founder of Bulletproof Coffee, and the father of biohacking.
