Is Magnesium Fluoride natural?

Yes. Magnesium and ionic fluoride are mineral-origin ions; the salt occurs as the mineral sellaite and is made from magnesium oxide or carbonate with fluorspar-derived hydrofluoric acid.

How we scored it

MgF2: Mg 24.3 Da + 2 F 38.0 Da, all mineral (magnesium source plus fluoride from fluorspar); 62.3 / 62.3 = 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

Magnesium oxide, hydroxide or carbonate from magnesite or seawater is reacted with hydrofluoric acid made from fluorspar. No petrochemical route exists.

In plain English

An inorganic mineral salt listed for anti-plaque and oral-care use. It is made from magnesium (from magnesite or seawater) and fluoride (from the mineral fluorspar).
