In this week's episode with Tom Benson, founder and CEO of Mitrix, you’ll explore why damaged mitochondrial DNA may be one of the true drivers of aging and why simply supporting mitochondrial function may not be enough. Tom explains how Mitrix grows healthy mitochondria in bioreactors using banked stem cells, what mitochondrial transplantation looks like in human studies already underway, and the remarkable mouse experiments in which aged mice became dramatically more active after receiving repeated mitochondrial injections. We also discuss why the body's natural mitochondrial quality control eventually breaks down, the connection between insulin, stress, and mitochondrial health, why current mitochondrial health tests may miss what's really happening inside your tissues, and much more!

The Mounting Science Behind C15:0 (& How to Save 15% Off) 🧬
Most people think about healthy aging in terms of wrinkles, aches, or lifespan.
But the real story begins much deeper, inside your cells. Every second of every day, your cells are repairing, adapting, and responding to the world around you. Supporting that process may be one of the smartest longevity strategies there is.

That's why one nutrient has been getting a tremendous amount of attention lately: C15:0, the first essential fatty acid discovered in more than 90 years.
The science behind C15:0 continues to grow. Two large prospective meta-analyses found that even small increases in circulating C15:0 levels were associated with better long-term cardiovascular and metabolic health.Clinical trials have also shown that supplementing with C15:0 raises blood levels of this unique fatty acid, with higher levels linked to healthier red blood cells, liver function, cholesterol metabolism, gut microbiome balance, and blood vessel health.
Developed by physicians and originally funded by the U.S. Navy, fatty15 is a patented, award-winning C15:0 supplement designed to support healthy aging at the cellular level.
Research suggests it supports more than 36 cellular pathways, and in a survey of 6,243 fatty15 customers, 70% reported noticeable improvements within 16 weeks, including better sleep, mood, and energy.
Fatty15 has become a regular part of my healthy aging stack because I believe the strongest longevity strategies begin at the cellular level.
