Welcome to the Lifespan podcast where we discuss the science of aging and how to be healthier at any stage of life.

I'm David Sinclair. I'm a professor at Harvard Medical School and co-director of the Paul F. Glenn Center for Aging Research

And I'm joined today by my lovely co-author and co-host Matthew Lapland. Hey, hey, we do them.

Feel good to have it again. We are. We're here today to talk about

how to live longer and better as part of this podcast series. Yeah, the series.

The things that you can do to slow stop and reverse aging. That is true. And today is going to be a really interesting one.

This is going to be the one that everybody, I mean, this is the one that everybody's been begging for.

That is true. We've been monitoring the responses to tweets and Instagram posts and

most of them are David just tell us what to take. The nice ones. Yeah, some of those aren't very nice either,

but yeah, please, please, please. Should I take NR? Should I take NMN? What should I do with Metform?

And we're going to be talking about all of that today. We are. And our research team has been spending weeks on this.

And if you can't see I'm actually sitting in front of many pages of notes here, we're going to go deep dive into what is fact

and what is not fact, what is known, what is not known, because there's so much misinformation out there, especially with supplements.

Yeah. We do need to say we usually take a moment to think our sponsors. We're going to do that, of course, but we also have to take a moment to say we are not medical doctors.

We are not medical doctors. We are not medical doctors. What he said. I'm a PhD. I'm a researcher. I can read the literature. I've been doing it for the last 30 years.

I distill that for everybody. But of course, if you want to try supplement or even change your diet radically, please talk to your physician before you change any thing.

Because some of the things we'll talk about today can affect your body in hopefully many good ways, but sometimes can be dangerous depending on the person and everybody's different.

And what we want to do is give people the ability to have a more intelligent and formed conversation with their physician.

Exactly. Okay. With that out of the way, now we should thank our sponsors.

Let's do that. Because this podcast is free to anybody who wants to watch or listen. Our first sponsor is levels.

Levels is an app that syncs with a continuous glucose monitor, which they provide and it interprets your glucose data for you.

I've been so impressed by levels that I've recently joined them as an advisor. Monitoring your blood glucose allows you to see how different foods impact you.
