How Nitric Oxide Supports Vascular Health and Healthy Aging | The Deep Six | Episode 36

On this episode of The Deep Six, Dr. James Lewerenz sits down with Cathy Eason, MS, BCHN, FNTP, Chief Science Officer at Berkeley Life, to unpack why nitric oxide is so central to vascular health, aging, and daily performance. Cathy explains how nitric oxide works in the body, why levels decline with age, and why endothelial health must be a lifelong priority, not just a concern after symptoms show up.
They explore the difference between amino acid-based approaches like arginine and clinically studied dietary nitrates, the role of the oral microbiome and saliva in nitric oxide production, and how support can impact blood pressure, energy, recovery, cognition, sexual wellness, and more. Cathy also previews upcoming research in peri- and post-menopausal women and shares practical reasons nitric oxide support belongs in every long-term prevention strategy.
