Why I built Minvelle.
I'm Max. I'm 20, from Austria, and I built this in the evenings because the product I wanted to buy did not exist: a gum with the enamel mineral actually in it, from a brand that prints its numbers instead of hiding behind a flavour name.
This page is the personal version. The factual one, with the legal entity, the founding date and the registered address, lives on the company page.

It started with iced coffee.
Cold sensitivity. The kind of twinge you ignore until you can't. I did what everyone does: sensitivity toothpaste, then whitening strips, then a more expensive sensitivity toothpaste.
Each one promised to fix it. Each one managed the symptom. And that is the part I couldn't get over: the oral care aisle is built around living with enamel loss, not around doing something about it. There is no incentive to change that when the same tube gets bought every two months.
An ingredient hiding in plain sight.
I went into the research. Trial papers, dental journals, regulatory filings; most of it paywalled, so I bought access.
The pattern was hard to miss: hydroxyapatite, the mineral family your enamel is built from, has been used in Japanese oral care since 1980 and was approved there as an anti-cavity agent in 1993. Decades of ingredient-level research. And in Western Europe, almost nobody talks about it.
"Four decades of use in Japan. Reviewed by the EU's scientific committee. And the aisle in my supermarket had never heard of it."
What three months of reading came down toMy honest guess for why: nobody with shelf space has an incentive to bring it across. Symptom management pays better.
Why a gum.
Contact time. Toothpaste is on your teeth for about two minutes. A piece of gum is chewed for fifteen, twenty minutes, and chewing drives saliva flow, which is what carries minerals to the tooth surface. The gum sits alongside fluoride brushing; it does not replace it.
So I built the formula around three things:
Nano-hydroxyapatite per piece. The same mineral family your enamel is built from, at a published dose.
Xylitol per piece. The oral-health-studied polyol that drives saliva flow while you chew.
Mastic gum in a plant-based base of chicle and spruce. Chewed for oral health since antiquity.
Sugar-free, fluoride-free, no aspartame, no titanium dioxide. It contains egg shell powder as a natural calcium source, so it is not vegan, and we say so on the box. One piece a day; a box of 18 lasts 18 days. All fourteen ingredients are published by weight on the transparency page, next to the independent lab reports.
What Minvelle is, and what it isn't.
It is a routine
A 15-minute habit after coffee that gives a well-studied ingredient real contact time. Alongside brushing, never instead of it.
It isn't a miracle
We will not tell you this gum rebuilds enamel or fixes cavities, because no finished-product trial says so. If your teeth are healthy and symptom-free, you may not need it.
It is verifiable
Published doses, published lab reports, a batch lookup, and a change log. If we alter the formula, you will see it before we ship it.
Try it without the risk.
The guarantee: within 30 days, send unopened boxes back for a full refund.
