Nano Hydroxyapatite is Safe and Effective

Hydroxyapatite is the building block of your enamel and bone. This mineral creates hard and strong teeth and bones.

In the 1970s, NASA created a synthetic version of Hydroxyapatite. They discovered that Nano-sized particles re-mineralized enamel and bone. In zero gravity, astronauts would experience enamel and bone loss. Nano-hydroxyapatite corrected this problem.

Later that decade, a Japanese company created an enamel restoring Nano Hydroxyapatite toothpaste

When your saliva is acidic, it erodes your enamel and bone. Neutral to slightly alkaline saliva allows Nano-Hydroxyapatite to re-mineralize enamel and bone. It re-mineralizes by filling in the pores of enamel and bone. Nano-hydroxyapatite is safe to swallow, unlike fluoride toothpaste.
