In this episode, my guest is Dr. Peter Attia, M.D., a Stanford and Johns Hopkins School of Medicine-trained physician expert in improving human healthspan and lifespan. Dr. Attia is also the host of The Drive podcast and author of the best-selling book Outlive. We discuss the NAD pathway in human cells and its possible links to aging and health. We evaluate how supplementation can augment molecules in the NAD pathway; we compare NAD, NMN, and NR, different routes of administration, their safety, and bioavailability. Then, we discuss the broader research and clinical literature on longevity to decide if supplementation with NAD, NR, NMN, rapamycin, or resveratrol can indeed extend lifespan. Finally, we each describe our supplement regimens and compare the role of supplementation to behaviors such as sleep, nutrition, and exercise for longevity. We also discuss whether tests of biological age are true indicators of aging and whether normal radiation levels increase cancer risk. Listeners of this episode will learn if supplements purported to improve lifespan show any efficacy and the behaviors and other factors that can prevent disease and extend lifespan.

Full Episode
Welcome to the Huberman Lab Podcast, where we discuss science and science-based tools for everyday life. I'm Andrew Huberman, and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine. My guest today is Dr. Peter Attia. Dr. Peter Attia is a medical doctor who did his training at Stanford University School of Medicine and Johns Hopkins School of Medicine.
Dr. Atiyah is one of the world's most trusted voices on the topics of healthspan and lifespan, and with good reason. He is known to systematically review the research literature, the clinical trials, and he maintains an avid clinical practice.
So when it comes to the topic of whether or not a particular molecule or supplement or prescription drug is indeed something that we should be thinking about and perhaps even taking in order to improve our healthspan and lifespan, Dr. Atiyah is the person that I choose to sit down with and discuss it. So today we are going to discuss the so-called NAD pathway.
This is a pathway that's received a lot of attention in recent years as a potential target for improving lifespan, that is for living longer. Today we discuss the various molecules in this pathway and the various approaches to increasing NAD, which is the end target goal of anyone that's trying to augment the NAD pathway, so to speak. So for instance, we talk about taking and R.
versus NMN versus direct infusions, or even orally taking NAD. And we compare them in terms of both what's known and what is not known about their ability to get into cells and any efficacy they may have for either longevity or healthspan.
Dr. Atiyah and I compare and contrast the literature on this, again, both research and clinical literature, and we discuss whether or not he or I take NAD, NMN, or NR. And if so, or if not, the reasons for that. We also each go through our own supplement regimen, which of course reflects what we do believe can potentially have an effect on healthspan and or lifespan.
So by the end of today's episode, you'll learn a lot about NAD. You'll learn a lot about the biological pathway. You'll learn a lot about the delivery routes, the various supplements, and why people think they may be useful, why others, perhaps even Dr. Atiyah and myself, think they may not be useful for longevity. You'll have to listen to find out what the answer is there.
I should also mention that we give somewhat of an overview or a framework for thinking about approaches to longevity. So if you're interested in things like rapamycin, metformin, and whether or not fasting can improve longevity, we get into that as well. Before we begin, I'd like to emphasize that this podcast is separate from my teaching and research roles at Stanford.
It is, however, part of my desire and effort to bring zero cost to consumer information about science and science-related tools to the general public. In keeping with that theme, I'd like to thank the sponsors of today's podcast. Our first sponsor is Element. Element is an electrolyte drink that has everything you need and nothing you don't.
