Seven of the 100 people ranked in the Unfiltered Longevity 100 for 2026 publish regularly for a general audience — a podcast, a newsletter or both. They are Peter Diamandis, Mark Hyman, Bryan Johnson, Matt Kaeberlein, Andrew Huberman, David Sinclair and Phil Newman. Three of them are working scientists and four are not.

Four more names belong on any honest version of this list and appear nowhere in the ranking at all: Peter Attia, Rhonda Patrick, Eric Topol and Aubrey de Grey. They are covered further down.

That ratio is the useful finding. The people producing the evidence in this field and the people explaining it are largely different populations, and the overlap is seven out of a hundred. Following the field well means reading across both groups and knowing which one you are reading at any given moment.

The seven longevity influencers worth following

Peter Diamandis. Founder of XPRIZE and managing partner at BOLD Capital, ranked 26th. The Moonshots podcast and his newsletter cover longevity inside a wider frame of exponential technology, which makes them useful for capital flows and weak on clinical detail. He is an investor in the field he covers.

Mark Hyman. Co-founder of Function Health, ranked 37th. The Dr. Hyman Show is among the largest health podcasts in the world and reaches an audience the research community does not. He co-founded a diagnostics company, so read the testing recommendations with that in view.

Bryan Johnson. Founder of Blueprint, ranked 45th and the highest-placed of the three people the ranking classifies as influencers rather than scientists, founders or investors. He publishes his own biomarker data in more detail than anyone else alive, which is genuinely valuable, and he sells the protocol that produces it, which is the caveat.

Matt Kaeberlein. Principal investigator on the Dog Aging Project and CEO of Optispan, ranked 86th. The Optispan Podcast is the closest thing the field has to a working scientist talking publicly without a product to move, and he is unusually willing to say when the evidence is thin.

Andrew Huberman. Host of Huberman Lab, ranked 90th. The largest audience of anyone on this list by a wide margin, with the corresponding trade-off: enormous reach, protocol-level specificity that sometimes runs ahead of the underlying human data.

David Sinclair. Harvard professor and co-founder of Life Biosciences, ranked 92nd. The Lifespan podcast and the Lifespan Insider newsletter carry a substantial peer-reviewed record behind them and a substantial commercial position alongside them. Both are relevant.

Phil Newman. Founder and chief executive of Longevity.Technology, ranked 99th. Trade coverage rather than personal commentary, and the most consistently useful source on the sector’s deal flow and company news.

How this list was built

Every name is drawn from the Unfiltered Longevity 100, which ranks the hundred people most actively shaping longevity across five weighted criteria. The additional test applied here is whether the person publishes regularly for a general audience under their own name, and whether that output could be verified as active. Seven met it.

The list is deliberately bounded by that verification. Several people in the Longevity 100 have written books, speak at conferences or appear as guests on other people’s shows, and none of that is the same as publishing regularly. If someone is missing who runs an active podcast or newsletter, that is a gap in the checking rather than a judgement, and the page will be updated.

Notable others: the most-followed voices who are not in the ranking

Four of the most widely followed people in longevity do not appear in the Unfiltered Longevity 100 anywhere. That is not an oversight. The ranking scores power over the field — capital deployed, science produced, companies built, direction set. These four exert influence over the audience rather than over the field, and the two are not the same thing. It is the cleanest illustration available of the gap this page is about.

Peter Attia. Physician, founder of Early Medical and author of Outlive. The Drive is the most technically detailed long-form interview show in the field by some distance, frequently running to three hours on a single mechanism, and it is the closest thing to a graduate seminar available to a general audience. He is a practising clinician with a private patient practice, which shapes what he emphasises.

Emails between Attia and Jeffrey Epstein, dating from 2015 and 2016, were made public in the Epstein files released in February 2026. Attia apologised for correspondence he described as “embarrassing, tasteless, and indefensible”, said he had never visited Epstein’s island and had never been his physician, and parted company with the supplement brand AG1 and the protein company David in the aftermath. He has not been accused of any wrongdoing by authorities.

Rhonda Patrick. Biochemist and founder of FoundMyFitness, which publishes a podcast and a research newsletter. She is unusually rigorous about citing the primary literature and unusually clear about the difference between mechanistic and clinical evidence — and she also sells a membership product, which is worth knowing. We have looked at her track record in detail in who is Rhonda Patrick and should you listen to her.

Eric Topol. Cardiologist, founder and director of the Scripps Research Translational Institute, and author of Super Agers, published in 2025. His Ground Truths newsletter and podcast are the most mainstream-academic output on this page and the only one with no commercial product attached to it, which makes him the natural counterweight to everyone else here.

Aubrey de Grey. Founder and Chief Science Officer of the Longevity Escape Velocity Foundation, which he launched in 2022, having founded the SENS Research Foundation in 2009. He is among the most cited names in the field and one of very few people willing to attach specific timelines to substantial life extension, which makes him worth following whether or not you accept the thesis. His output is interviews, talks and conference appearances rather than a regular show. We interviewed him on why ageing should be treated as a disease rather than a destiny. Worth knowing that a good deal of the material circulating about him still describes his former role rather than his current one.

What to weigh when following anyone in longevity

Most of the people on this page have a direct commercial interest in the products or services they discuss, which is disclosed in each case above and is not in itself disqualifying — almost everyone doing serious work in this field is also building something. What matters is whether they tell you unprompted. The other tests worth applying: whether they distinguish clearly between results in mice, in cell lines and in humans, which is the single most common place longevity claims break; whether they cite the primary study rather than the press release; and whether they have publicly changed their position on anything, which in a field this young is a stronger signal than consistency. We have written separately on whether you can trust celebrity scientists.

Who are the most credible voices in longevity?

That is a different question with a different answer, because credibility and reach are close to uncorrelated here. Only three of the seven people on this page are working scientists. Our ranking of the 38 most credible scientific voices in longevity covers the researchers whose standing rests on peer-reviewed output and institutional position rather than audience.

Frequently asked

Who is the best longevity influencer to follow?

It depends what you want from it. For technical depth on a single subject, Peter Attia’s The Drive. For primary-literature rigour, Rhonda Patrick’s FoundMyFitness or Eric Topol’s Ground Truths. For the largest audience and the most protocol-level detail, Andrew Huberman. For a working scientist talking publicly without a product to move, Matt Kaeberlein. For sector news and deal flow rather than personal advice, Phil Newman’s Longevity.Technology. Following one alone is the mistake.

Are longevity podcasts reliable?

They vary, and the useful test is not the host’s credentials but whether the claims are traceable. A podcast that names the study, states whether it was in humans, and says what the commercial relationship is can be checked. One that does none of those things cannot, however well qualified the person talking.

Which longevity researchers have podcasts?

Of the 38 working scientists in the Unfiltered Longevity 100 for 2026, two publish regularly under their own name: Matt Kaeberlein, with The Optispan Podcast, and David Sinclair, with the Lifespan podcast and the Lifespan Insider newsletter. That is two out of thirty-eight, which is the clearest available illustration of how little overlap there is between doing the research and explaining it.

Is the longevity industry legitimate?

Partly. It is a legitimate scientific field with regulatory milestones behind it, and it carries a consumer marketing layer that is not. Our full assessment is here.
