Supplement red flags: what the sellers' own labels and pages show.
We checked 33 heavily advertised supplements against their sellers' own sales pages, supplement facts labels and refund policies, and against the published research. This table collects what we found. Every row links to a full review with its sources. Last checked October 2026.
Key findings
What the 33 products have in common
- 23 of 33 hide some or all of their doses: 10 show no doses at all, and 13 put key ingredients in a proprietary blend. Sugar Defender's label lists 0.7 micrograms of chromium and 22 other ingredients in 200 mg.
- 29 of 33 send returns to one of two addresses: 14 to 19655 E 35th Dr in Aurora, Colorado, which Java Burn's help center identifies as the warehouse ShipOffers, and 15 to 285 Northeast Ave in Tallmadge, Ohio. The products are sold under different brand names.
- 19 products have labels or pages that contradict their own sales pitch, such as a tinnitus supplement whose label is marketed for memory and mood.
- 13 products have a Trustpilot profile under their name that belongs to a different website (nutrihealthsource.com) and has no reviews.
- 4 products are marketed in ways that point people away from proven treatment: one sales page says antiviral drugs do not work, another features a buyer expecting to come off diabetes medication.
- Two products stood up reasonably well: Joint Genesis and ProstaVive disclose their doses and offer 180-day refunds that cover empty containers.

Method
How we checked
- We read each seller's own sales page, supplement facts label, refund policy and help pages, and saved the dates. Where a site had gone offline, we used the Internet Archive.
- We compared the claims with systematic reviews, Cochrane reviews and NIH fact sheets, and with independent sources such as Trustpilot, the BBB, ScamAdviser and journalists' investigations.
- We left out anything we could not confirm at the source, and each review lists what we could not verify. We have not bought or lab-tested the products.
- A shared returns address does not prove a shared owner. It shows that the products use the same fulfilment operation.
