Podcasts and YouTube channels are great for staying current, but blogs and websites are still where the deepest written longevity content lives. A blog post takes longer to produce than a podcast episode, which means the best longevity blogs tend to be more carefully researched, more thoroughly cited, and more useful as reference material.
Below are the 10 longevity blogs and websites we recommend in 2026. They range from personal blogs by working scientists to industry news sites to deep reference databases. We have no affiliate relationship with any of these sites — this is a purely editorial list.

How we ranked these blogs
Three criteria:
- Depth and rigor. Does the site publish carefully researched, well-cited content — or is it mostly aggregated press releases?
- Update frequency. Is the site actively publishing new content, or has it gone dormant?
- Practical value. Can you actually use the content, or is it purely informational?
#1 — Peter Attia's blog
Peter Attia's blog (peterattiamd.com) is the gold standard for written longevity content. Attia publishes long, carefully researched essays on topics like ApoB, zone 2 training, cancer screening, and longevity pharmacology. The posts are dense — many run 5,000+ words with extensive citations — but they're the closest thing the field has to a definitive written reference. His weekly email newsletter is also worth subscribing to.
Best for: Anyone who wants clinical depth and is willing to read 30+ minutes per post. The exercise and lipid posts in particular are essential reading.
#2 — Lifespan.io
Lifespan.io is a nonprofit news and advocacy site focused on the longevity science field. They publish well-researched news articles on new papers, clinical trial updates, and industry developments, with a more pro-longevity-research editorial stance than mainstream science journalism. They also run crowdfunding campaigns for specific research projects.
Best for: Staying current on longevity research news and industry developments. Particularly good for tracking which therapies are in clinical trials and what stage they're at.
#3 — Longevity Technology
Longevity Technology (longevity.technology) is a B2B news site covering the longevity biotech industry. They publish daily news on funding rounds, clinical trial readouts, regulatory developments, and company launches. If you want to understand the industry side — who's investing in what, which companies are likely to succeed, what the FDA is doing — this is the best single source.
Best for: Industry and investment perspective on longevity. Less useful if you want personal health protocols.
#4 — Fight Aging!
Fight Aging! (fightaging.org) is one of the longest-running longevity blogs on the internet, published by Reason (a pseudonymous blogger who also writes for the libertarian magazine of the same name). The site has been publishing daily on longevity science, advocacy, and policy since 2004. The perspective is explicitly pro-rejuvenation research and somewhat libertarian in policy orientation, but the research coverage is extensive and well-sourced.
Best for: Daily research coverage with an advocacy lens. The archives are a treasure trove if you want to trace the history of specific interventions over the past two decades.
#5 — LeafScience
LeafScience (leafscience.org) is the educational arm of the Lifespan.io / Major Mouse Testing Program family. They publish explainer articles on specific longevity topics — what senescence is, how mTOR works, what the ITP tests, etc. The content is well-written and accessible, with good visual aids. Particularly useful as a reference if you're trying to understand a concept you encountered in a podcast or paper.
Best for: Concept explainers and educational reference material. Good companion to our Longevity Glossary.
#6 — NIA blog
The National Institute on Aging (nia.nih.gov) publishes research updates, funding announcements, and consumer-facing health information. The content is more conservative than the enthusiast blogs — you won't find bold claims about reversing aging — but it's authoritative. Particularly useful for understanding what the official US government position is on specific interventions and for tracking federally funded research.
Best for: Authoritative, conservative reference. If you want to know what the medical establishment thinks about a topic, start here.
#7 — Science Daily Longevity
Science Daily aggregates press releases from research institutions and journals, organized by topic. Their longevity section is a useful firehose of new research announcements. The advantage is breadth — you'll see papers from journals and institutions you wouldn't otherwise encounter. The disadvantage is that press releases overstate findings more than the underlying papers do.
Best for: Staying current with new research. Pair with a more skeptical source to contextualize the claims.
#8 — Reason Magazine anti-aging
Reason magazine (reason.com) covers longevity science and policy from a libertarian perspective, with a focus on FDA reform, right-to-try laws, and the regulatory environment around experimental therapies. The longevity-specific content is interspersed with broader policy coverage, but the archive of longevity-related articles is extensive.
Best for: Policy and regulatory context. Less useful for personal health protocols.
#9 — Examine.com
Examine.com is technically a supplement database rather than a blog, but it's the single best written reference for evidence-based information on supplements. They publish detailed evidence summaries for hundreds of supplements, graded by the strength of the evidence. The site is subscription-funded (no ads) and the content is meticulous. If you want to know what the evidence actually says about a specific supplement — including the evidence quality — Examine is the place to start.
Best for: Evidence-based supplement reference. Pair with our Supplements hub for product recommendations.
#10 — Levels Health blog
The Levels blog (levelshealth.com/blog) is published by the CGM company Levels, but the content is genuinely useful and not just product marketing. They cover metabolic health, glucose response, nutrition, and the practical use of CGMs in non-diabetics. The writers include working scientists and clinicians, and the content is well-cited.
Best for: Metabolic health and CGM use. Pair with our Best CGMs guide for product recommendations.
How to actually use blogs to learn
Subscribe to a few, not all
You can't read 10 longevity blogs regularly. Pick 2-3 that match your interests — Attia for clinical depth, Lifespan.io for news, Examine for supplement reference — and follow them. Add or rotate as your interests change.
Use RSS or email newsletters
Most of these sites publish RSS feeds and/or email newsletters. Subscribing by email is usually the lowest-friction option. RSS works well if you use a feed reader (Feedly, Inoreader, etc.) and want everything in one place.
Save reference posts
Some blog posts are news — read once and move on. Others are reference — you'll want to come back to them. Use a read-later service (Pocket, Instapaper) or a notes app to save reference posts. Our site is designed to serve the reference role for many topics — see our Glossary, FAQ, and Guides hub.
Cross-reference with primary literature
The best blogs cite their sources. When a post makes a claim that would change your behavior, look up the underlying paper. Most are free on PubMed. The blogs on this list are reliable, but no blog is perfect — verify anything important.
The bottom line
The written reference layer of the longevity field is smaller and more curated than the podcast or YouTube layer, which is a feature. Pick two or three blogs from this list, subscribe to their newsletters, and read consistently. Over a year you'll build a much deeper understanding than you would from listening to podcasts alone.
