Dr. Martin Picard: Professor of behavioral medicine at Columbia University and a leading mitochondrial psychobiologist. His lab famously showed that hair graying is linked to stress and is at least temporarily reversible.
What this episode covers
Andrew Huberman and Dr. Martin Picard go deep on what mitochondria actually do, arguing they are not just the 'powerhouse of the cell' but energy-transformation and energy-distribution organelles that act as antennas linking psychological experience to organ health and aging. Picard frames life itself as the flow of energy through the body, explaining emotions, sickness behavior, stress, sleep, and meditation through an 'energy resistance' lens. They cover why you can't simply eat more to get more energy, how exercise and inflammation compete for a finite energy budget, and the limits of gene-centric and one-size-fits-all RCT thinking. Practical themes include sleep, meditation/NSDR, fasting, alcohol's energetic cost, and skepticism toward the supplement and peptide craze. The episode closes with Picard's view that self-awareness of your energetic state is a kind of human superpower.

Energy
Martin Picard
“I was, you know, starting to work on on the book Energy and then I thought, Oo, this is such a a cool opportunity.”— Martin Picard
Protocols: An Operating Manual for the Human Body
Andrew Huberman
“I have a new book coming out. It's my very first book. It's entitled Protocols, an operating manual for the human body.”— Andrew Huberman

Coenzyme Q10 (CoQ10)
(supplement, generic)
“co-enzyme Q10 a number of people including me take. This isn't a plug for it. It's just I take it. I was told that can help my mitochondria.”— Andrew Huberman
NAD
(compound, generic)
“that was regulated by NAD. And so NAD seems to be kind of a dial on, you know, the rate at which energy is transformed.”— Martin Picard
Urolithin A
(compound, generic)
“There's some good data on urolithin a that improves quality in cultured cells and then in animals.”— Martin Picard
Ubiquinol
(supplement, generic)
“the recommendations of ubiquininal and CoQ10 urolithn. These are very prominent in the in the health space especially in the fertility health space”— Andrew Huberman
Big reveals from this episode
- Picard claims no more than ~10% of how long you live is genetically driven, with the best studies near 7%.
- Picard confirms hair graying is at least temporarily reversible, contradicting the idea that aging is purely linear.
- A participant's white-then-dark hair segment mapped almost perfectly to her two most stressful months, which then reversed.
- In a New England Journal trial, blocking GDF-15 to reduce nausea doubled mortality, suggesting the body's instinct not to eat is protective.
- Expert meditators can drop energy expenditure by ~40%, more than the ~10-15% saved by sleep.
- Picard, who watched SS-31's discovery, says the much-hyped mitochondrial peptide has mostly failed its trials.
- A Columbia mitochondrial scientist reveals he has never taken a single supplement.
- Both Huberman and Picard say they would not inject popular peptides (SS-31, MOTS-c, BPC-157, etc.) or let family do so.
Worth remembering
- 100% of your mitochondrial genome comes from your mother; longevity heritability is more maternal than paternal.
- Training for a marathon can roughly double the number of mitochondria in your muscles.
- The record for not eating is a Scottish man who fasted 382 days and lost around 250 pounds.
- It's a myth that basal metabolism slows in adulthood; the science says it stays flat from your 20s until about age 70-80.
- IL-6 spikes after you stop exercising, not during, signaling fat and liver to mobilize energy.
- GDF-15, a marker of cellular energetic stress, is the trigger for morning sickness in pregnancy and can rise ~10,000-fold.
- Forensic hair DNA comes from mitochondrial DNA, which is highly concentrated in hair, not the nuclear genome.
- US alcohol consumption recently hit roughly its lowest level in about 90 years, down around 50%.
- Adding a stress hormone to human cells in a dish raised their energetic cost by about 60%.
- Picard's lab is analyzing mitochondria from ~5,000 human brain and muscle samples drawn from 500 people.
