Rating Methodology
Every supplement entry in our knowledge base includes a few numeric indicators — below we explain exactly how we calculate them, so you can judge their reliability yourself.
Evidence Score (1–5)
The Evidence Score is our editorial, numeric synthesis of the strength of scientific evidence behind a given supplement or intervention — determined by the VitMode editorial team based on the number, quality, and consistency of available clinical studies. It isn't an automated algorithm and it isn't a rating assigned by a physician — it's an editorial assessment, explicitly tied to a descriptive label:
Strong evidence (4–5/5)
Numerous randomized clinical trials in humans and/or meta-analyses with consistent, reproducible results.
Moderate evidence (3–4/5)
Promising human clinical trials, but limited in number or size.
Preliminary evidence (1–2/5)
Mostly animal studies, in vitro research, or small human pilot studies.
Research hypothesis
A mechanism plausible based on biology, but poorly or not at all studied clinically.
The Evidence Score is independent of a supplement's popularity or price — a high evidence rating doesn't mean a given supplement is right for everyone.
Reader ratings
We do not collect reader ratings and do not show star ratings or averages. The only measure of the strength of evidence is the Evidence Score described above. Whether a supplement suits you is always a decision for your doctor.
Price ranges
The prices and monthly costs shown are indicative market ranges for the Polish market, updated periodically by our editorial team based on a review of offers from multiple manufacturers and retailers. We deliberately don't point to specific stores or present specific brands' offers as recommended — the ranges are meant to help with rough budgeting, not to direct you to a purchase from a specific seller. The actual price depends on the form, dose, brand, and place of purchase.
Editorial independence
Ratings and price ranges are not sponsored or set by supplement manufacturers. If an article contains sponsored content or affiliate links, this is always clearly disclosed — see our editorial process.
