Our Standards

How we report, and the rules we hold ourselves to.

These are the standards behind every article on Longevity Reviewed. They exist so you can trust that what you read here is driven by evidence, not by anyone's commercial interest.

1. Editorial independence

Longevity Reviewed accepts no brand sponsorships and runs no display advertising. No company can pay for coverage, for placement, for a favourable review, or to have a critical article softened or removed. Editorial decisions — what we cover, how we cover it, and what we conclude — are made by our editors alone.

If a company we've written about has a commercial relationship with us of any kind, that relationship is disclosed in the relevant article and never affects our assessment.

2. Evidence and sourcing

We build our reporting on the best available evidence, in roughly this order of weight:

Systematic reviews and meta-analyses of human trials
Well-designed randomised controlled trials in humans
Large observational and cohort studies, read with their limitations in mind
Mechanistic, animal, and in-vitro studies — treated as hypotheses, not conclusions

We link to primary sources wherever possible so you can check our work. We distinguish clearly between what the evidence shows, what it suggests, and what is still unknown. We are especially wary of claims that rest on a single small study, animal data presented as if it applies to people, or research funded by the company selling the product.

Plain language, on purpose. We write for a curious non-specialist. Where we simplify, we try never to distort — and we'd rather add a sentence of nuance than leave a misleading impression.

3. Assessing supplements and products

When we evaluate a supplement, device, or protocol, we look at more than the marketing:

Evidence for the ingredient — is there credible human research at the dose used?
Formulation and dose — does the product actually deliver what the research studied?
Transparency and testing — are there third-party lab results and honest labelling?
Value — is the cost reasonable for any benefit that's actually supported?

When the honest verdict is that something is unproven or not worth the money, we say so plainly.

4. Affiliate links and disclosure

Some of our practical, buyer-facing articles contain affiliate links. If you click one and make a purchase, we may earn a small commission at no additional cost to you. This is one of the ways we keep the site running without ads or sponsorships.

Any article containing affiliate links is clearly labelled at the top with a disclosure.
Affiliate relationships never determine what we cover, how we rate a product, or where it ranks.
Our news reporting does not contain affiliate links.
We recommend products on the merits alone — a commission never buys a better verdict.

The simple version: if money is involved, we tell you, up front, and it changes nothing about our conclusions.

5. Corrections and updates

We aim to be accurate, and when we fall short we fix it openly. Substantive corrections are marked with a dated note explaining what changed and why. As the science evolves, we revisit and update older articles rather than leave outdated claims standing. If you spot an error, please let us know.

6. Funding and ownership

Longevity Reviewed is reader-first and independently operated. Our revenue comes from clearly-labelled affiliate links within a subset of our articles — not from advertising or sponsored content. We are not owned by, and do not answer to, any supplement brand, retailer, or manufacturer.

7. Medical disclaimer

Longevity Reviewed publishes journalism and general educational information about health and longevity. It is not medical advice and is not a substitute for professional care. Always consult a qualified healthcare professional before starting, stopping, or changing any supplement, medication, diet, or exercise regimen — especially if you are pregnant, nursing, managing a health condition, or taking other medication.
