The Disclosure Grades.
Nine hydroxyapatite gum brands, graded on one thing only: what they publish. Dose per piece, particle data, full ingredient amounts, downloadable lab documents, a guarantee in writing. Not how good the product is — what the label and the website actually tell you before you pay.
Grades recompute the day a brand publishes. Every underlying cell is sourced in the full database.
Five questions, scored mechanically
- Dose per piece published? A number, in mg, on the brand's own pages.
- Particle data published? Nano or non-nano, with a numeric size.
- Full ingredient list with amounts? Names alone score half.
- Lab documents downloadable? A CoA or safety data sheet you can open, not a badge.
- Money-back guarantee in writing? A stated window, findable in policy.
Scoring: published = 1 point · partial = ½ · not published = 0. A ≥ 4.5 · B ≥ 3.5 · C ≥ 2.5 · D ≥ 1.5 · F below. No editorial judgement, no quality opinion — anyone can recompute every grade from the table below.
The grades
✓ published · ± partial · ✗ not published. Source cells and dates for every entry live in the database; most recent full sweep 11 July 2026.

| D | Dentagum | 2.0 | ✗ not published | ± nano stated, size not stated | ± list, no amounts | ± heavy-metal figures shown as an image, not downloadable | ± conflicting: product page says 30 days, refund policy differs |
| D | VanMan | 2.0 | ✗ not published | ± bovine-bone HAp; nano status not stated | ± 6 ingredients, no amounts | ✗ none found | ✓ full refund, no time window stated |

Not graded: Larineco (site blocks automated reading — no cell could be sourced) and Baumkau (German-language shop, outside the database’s current scope). Both stay on the watchlist.
The fine print, up front
We sell one of the graded products.
This page is maintained by Minvelle. That is exactly why the grades are mechanical, the rubric is published, and every cell links to the brand’s own pages in the sourced database. Check us hardest. Corrections: max@minvelle.com — fixes are made in public.
A grade is not a quality verdict.
These grades measure disclosure, nothing else. A brand with an excellent product and a bare website scores low here; that is the point of the exercise, not a flaw in it. Nano and non-nano milligrams are also not directly comparable — a bigger number is not automatically a better one.
The standing offer, to every brand on this page.
Publish your dose, your particle data, or your lab report, and email us. Your grade is recomputed and this page is updated, with the date, at no cost, whether or not we like the result. The best outcome for buyers is a column of A grades — including the ones that beat ours.
Our own numbers, in the open.
