Evidence first

About CALQIX
Oral care built around what enamel actually needs.
CALQIX is a Dutch oral care brand focused on nano-hydroxyapatite, clean routines and clinically sensible products.
Most oral care starts with foam, flavour and habit. We started with enamel.
Nano-hydroxyapatite is a biocompatible calcium phosphate that mirrors the mineral structure of enamel.
We develop toothpaste tablets and oral care tools that make daily care clearer, lighter and more evidence-led.
No vague wellness claims. No complicated ritual. Just ingredients and tools that earn their place.
What we stand for
02
Full clarity
Clear formulas, honest claims and no unnecessary complexity.
03
Daily precision
Products should fit naturally into a routine and improve the basics every day.
The mineral behind the routine
Human enamel is largely made from hydroxyapatite. Acids and bacteria slowly weaken that mineral surface.
Nano-hydroxyapatite supports remineralisation by filling tiny surface irregularities and reinforcing the enamel feel.
