Among the podcasters, Andrew Huberman sits atop the rankings. A Stanford neuroscientist, he launched his show, Huberman Lab, in 2021, and today it’s regularly among the world’s top 10. He also has a forthcoming book, Protocols, which is supposed to be out this fall, although review copies weren’t available at press time. Huberman is a research scientist and a teacher, not a clinical physician, and while he covers a growing range of topics (recent episodes focus on grief, productivity, creativity, diet, hearing, and balance), the long episodes (often running more than two hours) sometimes involve dense talk about neurotransmitters and wonky studies. Huberman has also been criticized for promoting unproven supplements, some sold by his advertisers. Though I’d prefer shorter, more accessible episodes, I still listen frequently—and I recognize that Huberman’s focus on living better, instead of fixating on avoiding looming decrepitude, makes his work slightly more upbeat than other longevity pros.
