What is hydroxyapatite?
The short version: it's the same mineral your teeth are already made of.
Your tooth enamel is 97% hydroxyapatite — a natural mineral that gives your teeth their strength, smoothness, and color. Hydroxyapatite is a lab-made version of that same mineral, just sized small enough to work where your teeth actually need help.
Where did it come from?
Backed by NASA research, synthetic hydroxyapatite was developed in the 1970s to help astronauts restore tooth minerals lost in zero gravity. It was later adapted for toothpaste, approved for dental use in Japan in 1993, and is now trusted in over 70 countries worldwide.

How does it work in toothpaste?
Every time you eat or drink something acidic, your enamel loses tiny amounts of minerals from its surface. When you use LarineCo™ toothpaste twice daily, hydroxyapatite works to replenish those calcium and phosphate minerals.
Brushing with hydroxyapatite in the morning gives your enamel a strong mineral base for the day ahead, while brushing with it at night helps replenish minerals and helps clear away the food particles your teeth encounter throughout the day. Think of this as the building blocks to support stronger-feeling teeth and long-term oral wellness.
Is it safe?
Completely. Your body recognizes nano-hydroxyapatite as its own material. If swallowed, it simply breaks down into calcium and phosphate — minerals you already consume in food every day. It's been used in oral care products for over 40 years and has been extensively studied for safety and biocompatibility.

Frequently Asked Questions
Why switch from my current toothpaste?
Most toothpastes rely on fluoride, synthetic fillers, and artificial flavors as their primary ingredients. LarineCo™ is fluoride-free and free from artificial flavors. Our formula includes nano-hydroxyapatite, a biocompatible mineral your teeth are naturally made of, safe to ingest, and designed to help replenish minerals lost from everyday acid exposure. It also includes live probiotics to support your oral microbiome and bamboo charcoal to gently lift surface stains without peroxide or harsh abrasives.
Will this whiten my teeth?
Bamboo charcoal and silica hydrate gently polish away surface stains. No bleach. No peroxide. Just a brighter-looking smile over time.
What do the probiotics do?
Your mouth has a microbiome just like your gut, and it needs the right balance of bacteria to maintain a healthy pH and keep harmful bacteria from taking over. The Lactobacillus probiotics in our formula help maintain that balance to support fresher breath, gum comfort, and a healthy oral environment.
Why does LarineCo™ Remineralizing Toothpaste cost more than regular toothpaste?
Most toothpastes use cheap synthetic fillers, artificial flavors, and foaming agents designed to create the feeling of a clean mouth. We use high-quality, mineral-rich ingredients instead. Our Natural RMX50 Complex features hydroxyapatite with up to 50% of the formula dedicated to enamel-supporting ingredients, plus Lactobacillus probiotics to support your oral microbiome and bamboo charcoal for gentle whitening without harsh abrasives.
