100 Mid-Sized Longevity Podcasts Actively Seeking Guest Voices

If you're pitching clients with longevity expertise (physicians, researchers, biohackers, nutrition and fitness experts, healthspan coaches, founders of longevity products, authors) the biggest shows aren't where you'll get booked. Mid-sized longevity podcasts are.

Mid-sized shows (roughly 1K-25K listeners per episode) are the sweet spot for guest outreach:

• More accessible — Hosts are actively looking for credible longevity voices
• More likely to book — Less competition, faster response times
• More engaged audiences — Listeners who act on health and healthspan advice

This list features 100 longevity-focused podcasts that regularly interview guests on healthspan, aging science, metabolic health, biohacking, nutrition, fitness, and living better for longer.

What We Mean by "Longevity"

"Longevity" is a Podseeker category, not a standard Apple or Spotify one.

Longevity is one of the fastest-growing topics in podcasting, but it's brand new as a category and exists nowhere in the major directories. Shows touching healthspan, aging science, and biohacking are scattered across Health & Fitness, Science, and Education. A PR pro pitching a longevity physician needs different shows than one pitching a metabolic-health researcher, a biohacking founder, or a fitness-for-aging coach, even though all four speak to "longevity."

Podseeker has thousands of podcasts tagged under Longevity, spanning medicine, science, nutrition, fitness, and the broader healthspan movement. That's why it needs its own category. Someone searching "longevity" isn't after one vertical, they want shows where their client's specific expertise will land with an audience that cares about living longer and healthier.

You won't find this filter in generic directories. It exists because we focus specifically on podcast outreach, so the categories reflect how PR pros actually search.

How to Use This List

Don't pitch all 100. The users who book the most aren't the ones who pitch the widest, they're the ones who pitch the right shows.

1. Match the show to your client's specific angle

Fit is everything. Within longevity, shows want different things. A physician with clinical research, a biohacker with self-experiments, a coach with a protocol, these land on different shows. Look for genuine alignment between your client's expertise and what the show actually covers, not just topic overlap.

2. Check recent episodes

Before pitching, confirm the show is active and see what they've covered lately. Recent episodes are the clearest signal of fit, far better than a category tag. If your client's angle matches the last few guests, that's a strong show. If it doesn't, skip it.

3. Start with a focused batch

Pick the 10-15 strongest fits and pitch those first. A tight, well-matched batch outperforms a broad one almost every time.

4. Read the signal, then expand

If the right shows are replying, expand to more from the list. If they're not, the issue is usually fit, the client angle or the show selection, not the volume. Adjust before you scale.
