What if one simple molecule could improve your energy, brain clarity, hormone balance, and heart health? Functional nutritionist Dr. Cathy Eason joins us on The AGEIST Podcast to share why nitric oxide (NO) is an often-overlooked key to healthy aging, and how most people over 35 are deficient. She breaks down how testing your levels is a quick, simple way to know your NO levels (it only takes 15 seconds), as well as how to increase your NO through diet, lifestyle, and a clinically tested supplement. Plus, Dr. Eason also reveals why common habits like mouthwash and over-exercising may be silently sabotaging your health goals. Tune in to learn how it all connects.

Say hi to the AGEIST team!

This week, we welcome Dr. Chris Renna back to The AGEIST Podcast to break down one of the most hyped but least understood subjects in modern health: stem cells. Along with providing a clear explanation of how different types of stem cells function, he talks about how they interact with our immune systems and why most “stem cell therapies” people hear about are missing the point. Tune in to learn what actually works, the difference between redeploying vs. reloading stem cells, and the critical importance of starting any anti-aging protocol by age 30. For those of us interested in real longevity—not just the buzzwords—this episode delivers grounded, usable knowledge.
