Longevinsights: your health decisions deserve better than TikTok advice.
We read the papers so you don't have to: every longevity claim checked against peer-reviewed research.
Every claim is sourced to a peer-reviewed paper.
No sponsorship from supplement brands. Ever.
We never simplify past the point where the science still holds.
Is it legit?
Every claim below has been read against the papers. Yours can be next.
Check any longevity claim
Heard something about creatine, cold plunges or NMN? Type it in and we'll tell you what the peer-reviewed evidence actually says.
01We read the research
Trials, reviews and meta-analyses on that exact question.
02We weigh the evidence
A randomised trial counts for more than a mouse study.
03You get a verdict
Supported, partial, insufficient or debunked - with citations.
Every claim, with its evidence attached.
40 longevity claims read against the peer-reviewed record. Each verdict cites the studies it rests on - and moves when they do.
Science you can actually use.
In 3 minutes.
Each insight distils one peer-reviewed longevity study into something you can act on.
We read the papers
10,000+ longevity studies are published every year. 95% are noise. We find the signal - and focus only on studies with robust methodology.
We extract what matters
Each insight follows a clear structure: what to do, what the evidence says, why it works biologically, and the honest limitations.
You take action
No PhD required. Every recommendation is specific enough to implement today. You get the conclusion without wading through the methodology.
