In this episode with Tom Benson, founder and CEO of Mitrix, you'll hear why mitochondrial decline may be the actual root cause of aging rather than just a downstream symptom of it, and why most of the drugs developed so far to address it don't touch the real problem: damaged mitochondrial DNA. We discuss how Tom's company grows new, healthy mitochondria inside a bioreactor using banked stem cells, what mitochondrial transplantation actually looks like in real human cases already happening today, and the mouse study that gives this episode its name, in which severely aged mice receiving repeated mitochondrial injections were, according to the technicians running the experiment, climbing the walls of their cages by the very next day. Tom also touches on his original theory on the mitochondrial cycle of the body, how mitlets differ from naked mitochondria, and what his own MitoClock test reveals using nothing more than a urine sample.
Tom Benson is the CEO and founder of Mitrix. He is a serial entrepreneur and scientist who has founded four successful software, hardware, and science startups. He has published dozens of articles and video lectures on mitochondrial science and cellular energetics, and developed original theories on the systemic transfer and distribution of mitochondria within higher organisms and how that affects health and lifespan.

Mindsip insights from this episode:
Address energy depletion to enhance gene therapy effectiveness
Gene therapy to repair mitochondrial DNA inside the body may fail because an old, energy-depleted cell lacks the energy to perform the repairs.
Assess mitochondrial quality across different tissues
The quality of your mitochondria differs greatly throughout the body, with high-quality ones in the blood and notoriously low-quality ones in skeletal muscle.
Understand stem cell treatment's limited impact on aging
A typical systemic stem cell treatment of 150 million cells is only equivalent to reversing one or two days of aging.
Refurbish mitochondria through astrocyte support in brain cells
In the brain, support cells called astrocytes create new mitochondria, send them to neurons, and then receive the old ones back to be refurbished.
Transplant a billion mitochondria naturally during conversation
Your body naturally transplants about a billion mitochondria between cells through the bloodstream in the time it takes to have a short conversation.
Inject bioreactor-grown mitochondria to boost energy in aging mice
After receiving injections of bioreactor-grown mitochondria, old mice became so energetic that they were literally climbing the walls of their cages the next day.
Mitigate chronic stress to enhance mitochondrial health
Chronic stress hormones cause mitochondria to replicate quickly but with poor quality control, which prematurely ages them.
Question longevity treatments with nature's wisdom
A key principle for evaluating longevity treatments is asking, 'If it's that simple, why didn't Mother Nature already do it 100 million years ago?'.
