Nano-Hydroxyapatite in Toothpaste
What is Nano-Hydroxyapatite?
Nano-Hydroxyapatite (Nano-HAp) is a synthetic version of the naturally occurring mineral hydroxyapatite, which makes up about 97% of your tooth enamel. It’s biocompatible and meant to mimic the natural minerals in your teeth, making it an ideal ingredient for remineralizing your teeth.
Does Nano-Hydroxyapatite Cross the Blood Brain Barrier?
A most common concern is that Nano-HAp can cross the blood-brain barrier causing harm. New research shows that Nano-HAp does not cross the blood-brain barrier. Research shows it does not cross the epithelial barrier, does not get in your bloodstream, let alone the blood-brain barrier. https://pubmed.ncbi.nlm.nih.gov/33683238/
Why Nano-Hydroxyapatite is Safe for the Entire Body
When you swallow Nano-HAp it dissolves in your stomach’s acidic environment breaking down into calcium and phosphate- both essential minerals your body needs for various metabolic functions. Even if Nano-HAp did get into your bloodstream or cross the blood-brain barrier it would still break down into calcium and phosphate, which are vital for every cell in your body, including brain cells.
Bottom Line
Nano-Hydroxyapatite is a safe, scientifically-backed alternative to fluoride. Thanks to its inability to cross the blood-brain barrier and its complete breakdown in the stomach, Nano-HAp is a much safer alternative to fluoride, which does cross the blood-brain barrier and has profound effects on the development of the brain.
