Open the report Bonus: The Enamel Handbook
The handbook is our 40-page guide to enamel, 2nd edition. Yours with the report, no strings.
You asked whether remineralizing gum is legit. That is the right question, and no listing can answer it. The five checks can. Run them on any brand. Then run them on us.
You saw the ad. You looked for the number. It was not there.
You saw a gum advertised, got curious, and could not find out what was in a piece. You read twenty reviews and every one of them was about mint. You searched the brand with the word "legit" and found a complaint file where the science should have been. That is not you being difficult. That is a category that mostly does not publish, and it leaves you doing the brand's homework.
The five checks fix that in a minute. What they cannot do is make a brand publish. Only one brand in the table can be checked all the way down. We built it that way on purpose.
We publish the numbers. Then we hand you the checklist.
5.7 mg nano-hydroxyapatite per piece, stated. All fourteen ingredients with amounts, public. The supplier documents we have, downloadable. A public table where we grade ourselves on the same five checks as everyone else. And where something is missing, we say so: no finished-gum batch test exists yet, for us or for anyone in the table.
- Demonstration, not a badge. The documents are on the transparency page, the database is public, and the open chew log is a real diary of a real box, day by day.
- A person answers. Every email goes to Max, the founder. One reply, within a day, from the person who chose the dose.
- One piece a day, 18 in a box. Two boxes are 36 days: long enough to keep a sensitivity log and see whether anything changed for you.
"Asked for more reputable alternatives, and yours came high on the list. Transparent contents sealed the deal."

What the trials found, and what nobody has shown.
Most research on hydroxyapatite in the mouth is on toothpaste. A 2023 systematic review rated the sensitivity evidence low certainty. The EU's Scientific Committee on Consumer Safety published a safety opinion in June 2025 for toothpaste and mouthwash concentrations. Two small trials exist on gum, both on sensitivity. No trial on any gum has shown it prevents or reverses a cavity. Page 6 has the sources. A gum keeps the ingredient in contact with teeth between brushings. It is not a treatment, and the brand that tells you so is the one being straight with you.
Two boxes. Chew the first. The second stays refundable.
Most brands in this category will not tell you how much hydroxyapatite is in a piece. We publish it, so we can afford to let you check before you commit. 30-day money-back on the unopened box, and a named guarantee underneath it that no brand in the table can copy without publishing first.
Why two and not one: one box is 18 days, not long enough to log anything. Two boxes is a full cycle. One box at €24.99 is on the main page if you prefer.
Two boxes every four weeks for €29.99, the price locked for as long as you stay. Pause, skip or cancel from your account, no call, no form. Founding members get a direct line to Max and, only if you want, your first name on the transparency page. Closes at 100 members and does not reopen.
Take a founding placeRun the five checks on us.
Check 1: the dose is on the transparency page. Check 2: the supplier states 200 nm. Check 3: every amount is on the transparency page. Check 4: both documents are downloadable there, with a note on what each covers, and we mark ourselves partial because no finished-gum test exists yet. Check 5: the refund policy says the same thing the product page says.
PS The five checks work on us too. Find a cell we got wrong, email max@minvelle.com, and the table is corrected in public, with the date. That is the warning and the reminder in one: we are the brand that expects to be checked, and the founding count only moves in one direction.
