Built on evidence.
Accountable to readers.
Fitlab Reviews is an independent supplement research publication. No sponsored content, no brand partnerships, no paid rankings.
The supplement aisle is a marketing problem dressed up as a science problem.
We read the actual trials, compute the actual doses, and publish the result — including when it stings brands we're affiliated with.
- ✓Score every supplement on a published, frozen rubric — before looking at affiliate rates
- ✓Compute per-ingredient doses from proprietary blends using clinical thresholds
- ✓Verify third-party certifications and flag products that only carry manufacturer COAs
- ✓Publish a dated, auditable conflict-of-interest and affiliate disclosure policy
Transparent scoring
Our five-question rubric is published in full before any product is evaluated. Scores cannot be changed post-publication without a public changelog entry.
Editorial independence
Reviewers don't know which products carry affiliate relationships at evaluation time. Revenue never influences the final score.
Correction-first culture
When we get something wrong, we correct it with a dated public changelog note. No silent edits. Errors are acknowledged and fixed.

Every review has a name attached. Every claim has a citation. Every score has a methodology page explaining how we got there.
