About: Nano-Hydroxyapatite or (HAp).
Safety is everyone's number one concern! The EU has published on the safety of nano hydroxyapatite after an intensive non corporatized study by 12 scientists (11 toxicologists).

As per the guidelines presented therein:
We use nano hydroxyapatite with an abstract ratio of 2.2.
Our crystal size is 60 nano meter.
The concentration used in our toothpaste is less than 10 percent by weight
and the concentration in our drip serum and in our oral care chews is less than .45 %
Abrasiveness: Nano hydroxyapatite has been shown in numerous studies to support remineralization. This being considered, it is therefore counter intuitive that concerns have arisen over its abrasiveness. There are also very few studies which could be cited to support such a concern. Our enamel is 98 percent hydroxyapatite. Two things that are the same hardness generally don't scratch one another! Remember we also keep the percentage used in our recipes limited
according to the recommendations but please always make your own educated decision!
Observed effects of Nano-hydroxyapatite in various studies..
Enamel is the outer most microcrystalline coating of the tooth. It protects against tooth decay. Ninety-seven percent of enamel is made up of hydroxyapatite (HA).
Dentin is the second layer of the tooth situated right under the enamel and seventy percent of dentin is also HA. Dentin contains tubules or microscopic channels between the enamel surface and the dental pulp and these tubules travel all the way to the tooth nerve! Enamel is also full of thousands of micro pores.
Hydroxyapatite is a mineral, it is composed of calcium and phosphate and occurs naturally in bones. We use vegan friendly (HA), as the synthetic is just as reliable as real bone. Nano hydroxyapatite has to be created in a lab in order to produce the ultra-small particles of hydroxyapatite. Nano (HA) was first developed by Nasa to protect astronauts from de-mineralization in space. These days nano-hydroxyapatite (HA) is commonly used in osteopathy and in dentistry. The re-mineralizing abilities of this natural alternative to fluoride are well established!
The theobromine in our paste is also designed to work together with the nano\-hydroxyapatite. Theobromine stimulates an increase in the individual enamel crystal size, while nano (HA) provides the necessary calcium and phosphate building blocks. Our paste also features silica which has been found to affect the plating/scaling of calcium in water.
