Episode notes

ADVICE

Use At-Home Saliva Tests Frequently

Test hormones at home with frequent, easy saliva checks to get near-real-time results instead of waiting days for lab results.
Use the app's interpretation to track variation over time rather than relying on a single absolute value.

INSIGHT

Diurnal Rhythm Beats Single Readings

Cortisol follows a diurnal rhythm that should be high in the morning and low at night, and the rhythm matters more than a single reading.
Serial measurements reveal dysregulation of the HPA axis that one-off tests miss and guide targeted interventions.

ADVICE

Fix Hormones With Tailored Lifestyle Changes

Prioritize lifestyle changes (sleep, exercise timing, hydration, light exposure) as first-line steps to rebalance cortisol and progesterone.
Adjust exercise type, timing, and intensity based on your cortisol pattern to avoid worsening dysregulation.

We’ve always believed that data drives better health, but even we were surprised by how powerful hormone data can be. Hormones influence everything from how we age to how our skin repairs itself, yet most people only test them once a year, if at all.

In this episode, we sit down with Fady and Marina from Eli Health to explore how real-time hormone testing is changing the way we understand health optimization. Their saliva-based technology tracks cortisol and progesterone with over 90 percent lab-comparable accuracy, while their AI-powered app translates results into actionable lifestyle insights.

We also unpack how cortisol rhythm shapes energy, mood, and skin health, why “cortisol face” is real, and how frequent hormone tracking can help prevent stress-related aging before it appears on the skin. Fady and Marina, founders of Eli Health, are redefining hormone care with a science-driven, ethically designed platform that keeps data and decisions in your hands.
