Supplement Brief is written and edited by Daniel Hart, a science communications editor focused on evidence-aware supplement comparisons. Selected guides receive scoped medical review from Natallia Kalistratava, MD. We write for readers who already know what they are looking for and need a clearer answer on what is worth buying, what is overhyped, and where the evidence stops.
Why Supplement Brief exists
The same pattern kept showing up: supplements promoted with certainty, while the underlying studies were small, conflicted, or never replicated. Supplement Brief was started in 2026 to close that gap.
Most buying guides read like affiliate copy with a thin evidence veneer. Most clinical evidence stays locked in journals that readers never see. The space between those two is where readers get misled: by a single small trial stretched into a broad claim, by a “natural” alternative framed as a prescription replacement, or by a ranking that looks editorial but is paid. Supplement Brief sits in that space. The trials get read, what they actually measured gets written down, and the funding source gets named when a trial is industry-backed. The goal is to make the evidence legible enough that the reader can decide for themselves.
How guides are built
Every guide follows the same workflow at a high level:
- Identify the clinical question the reader is actually asking.
- Review the human evidence, prioritising meta-analyses and randomised trials, naming lower-tier evidence when that is all there is.
- Assess limitations: population, dose, duration, primary vs exploratory endpoints, funding source.
- Write practical guidance that separates what the evidence supports from what marketing claims.
The full methodology is on the methodology page: evidence hierarchy, industry-funded trial flagging, medical review policy, and where to find independent lab data.
What we do not do
- invent expert reviewers or paid authority badges
- accept payment for placement or paid rankings
- present animal or preclinical research as human evidence
- recommend a product because a brand pays for it
- overstate certainty when the evidence is limited, small, or industry-funded
Medical reviewers
Supplement Brief’s editorial content is written and fact-checked against cited sources. Selected articles with significant medical context also receive independent review from external clinicians. Those reviewers are named in the article byline and listed on the methodology page.
Our first external medical reviewer is Natallia Kalistratava, MD, a general practice physician licensed in the Republic of Belarus. See her profile for review scope, credentials, and limitations.
Good evidence doesn’t make decisions for people. It helps people make better decisions.
