Fake Supplement Reviews: How to Spot Them Before You Buy
Red flags in the text
- The same phrases repeated across many reviews.
- Adjectives without details ("amazing", "life-changing").
- Claims of curing a disease, which supplements may not make.
- Many reviews posted on the same day.
Check who is speaking
A review on a seller's own page, a paid blog or an affiliate site is advertising to some degree. We are an affiliate, which is why we do not publish star ratings we cannot verify and why we label the seller's own testimonials as such.
Look for balance
Genuine feedback usually includes trade-offs: what changed, what did not and what the reviewer also changed at the same time. Be wary of a page with no criticism at all.
Practical steps
- Read three-star reviews first.
- Search for the product name with words such as "refund" or "complaint".
- Check the seller's written terms, not only reviews.
- Use a credit card for dispute rights.
Where to report
If you believe a seller used fake reviews or deceptive claims, report it at ReportFraud.ftc.gov. For general advice on weighing health claims, see the NCCIH guide to using dietary supplements wisely.
A quick scoring method
Give a review one point for each of these: specific details, a reasonable mix of pros and cons, a verifiable reviewer, a date and a description of what else changed. Reviews scoring under three should carry little weight. Apply the same test to our own pages: we label seller testimonials as such and do not show ratings.
Safer research habits
Look for independent coverage, check regulators' pages and read the written refund policy. Be cautious when a page pushes a countdown or says a product is almost sold out.
