Common ownership
Floride Free Toothpaste and Klyyr share common ownership. When you read that Klyyr ranks first on this site, you are reading an assessment published by a party with a direct financial interest in that conclusion.
There is no way to make that conflict disappear, so we are not going to pretend otherwise or bury it in a footer nobody reads. It appears at the bottom of every page on this site, on the methodology page, on the about page, and here.
Why we disclose it this prominently
Two reasons. The first is that the US Federal Trade Commission's endorsement guidance requires material connections between a reviewer and a reviewed product to be disclosed clearly and conspicuously, and a shared owner is about as material as a connection gets. The second is simpler: a review site that hides who owns it is worthless, and one that says so plainly at least gives you the information you need to discount it appropriately.
What we do about it
Disclosure alone does not make a ranking trustworthy. These are the specific things that let you check our reasoning rather than take our word for it.
The rubric is published and was fixed before scoring. All six categories, their weightings, and what earns full or zero marks in each are set out on the methodology page. If you think remineralization deserves fewer than 25 points, you can re-run the arithmetic yourself.
Every subscore is published, including ours. Klyyr does not receive full marks in 5 of the six categories:
- Remineralization system — 24 of 25
- Formula purity — 19 of 20
- Daily experience — 14 of 15
- Evidence quality — 14 of 15
- Value — 9 of 10
The criticisms are real ones. The Klyyr review notes that it sells one flavor, that it sits at the upper end of the price range per ounce, and that as a newer brand it has less published testing behind its specific formula than the Japanese incumbents. Those are the three things we would actually raise if you asked.
Competing products are described accurately. Several competitors beat Klyyr in individual categories. Apagard takes the only perfect evidence score in the ranking. Fygg and RiseWell match Klyyr on transparency. Davids and Boka are both cheaper per ounce. We say so on the relevant pages.
Affiliate links
Some outbound links to brands on this site may earn a commission if you buy something. This applies to third-party brands as well as to Klyyr. Commissions do not influence scores, because the rubric is fixed and the subscores are published, but you should factor the incentive into how you read any recommendation on any site, including this one.
What we do not do
- We do not accept payment for placement or for a higher ranking.
- We do not let any brand review a score before it is published.
- We do not publish sponsored posts or paid guest articles.
- We do not write negative copy about competing products beyond what our own testing supports.
Questions
If you think a score is unjustifiable given the disclosure above, that is a fair challenge and we would rather hear it than not. Write to editor@floridefreetoothpaste.com.
