What if the fatigue, brain fog, low energy, and other symptoms we associate with getting older actually begin much deeper—at the level of our cells?

I've followed Dr. Will Cole's work for years, and his approach to gut health and functional medicine played an important role in my own health journey. Now he's taking that conversation one step further with his new book, Heal Your Cells, exploring what's happening inside our cells as we age—and what we can do to support them.

In this conversation, we break down the emerging science of cellular health and longevity, including why different organs may age at different rates, how mitochondrial dysfunction affects energy, and the everyday factors that can accelerate cellular aging.

In this episode, you'll learn:

Why cellular health may be the next frontier of longevity
How your biological and organ age can differ from your chronological age
How toxins and nutrient deficiencies can affect cellular function
Why mitochondrial health is critical for energy, metabolism, and healthy aging
How food, polyphenols, movement, and other lifestyle factors support your cells
What peptides are and why they're becoming a major part of the longevity conversation
What to know about emerging regenerative therapies like stem cells
Why emotional health, stress, relationships, and spirituality also belong in the longevity conversation

We also discuss oxidative stress, cellular signaling, food sensitivities, environmental exposures, and the growing number of tools designed to measure and influence how we age.

The biggest takeaway is that improving cellular health doesn't require doing everything at once. Start with one change. Support the foundations. Then build from there.

Because when we talk about longevity, we're ultimately talking about the health of the trillions of cells that make up who we are.
