If you’ve got a cupboard full of supplements you bought with good intentions but never used, this episode is for you. Cathy Eason, Chief Science Officer at Berkeley Life, talks about nitric oxide, a molecule that affects almost every body system, including blood flow, blood pressure, digestion, energy production, and sexual arousal.
She explains why nitric oxide production declines in your 30s and how it’s linked to perimenopause. Eason also discusses the research behind using dietary nitrates (like beets and leafy greens) to support nitric oxide production and when supplementation might be necessary.
This episode covers practical aspects like testing nitric oxide status at home, the connection between oral health and nitric oxide, and how the protocol differs for daily energy needs versus intense training. Eason also advises caution with nitric oxide supplementation, especially for those on blood pressure medication, and why she moved away from arginine/citrulline supplements.

![HRT Can’t Fix Your Ligaments: The Diabolical Role of Estrogen on Connective Tissue
⚡️ Watch Dr. Stephanie on the Diary of a CEO podcast at https://www.youtube.com/watch?v=HwVn3WMv5oI
Youve been training consistently for years. You know your way around a gym. And then, out of nowhere, a shoulder gives out on a weight youve pressed a thousand times. Or your knees start complaining on the stairs. Or your hips talk back on leg day — and nobody can find anything wrong on imaging.
This isnt aging. This isnt bad form. This is what happens when one system gets all the attention, and another one runs out of runway.
In this solo episode, Dr. Stephanie introduces the JTL — joints, tendons, and ligaments — the connective tissue system that holds your entire muscular strength together, operates on a completely different adaptation timeline than muscle, and has been systematically ignored by decades of fitness programming aimed at women.
