This is our bestselling remineralizing toothpowder recipe made with 33% hydroxyapatite! Our hydroxyapatite is NOT nano or lab-made (synthetic). It is naturally sourced from Australian bovine. Some speculate that synthetic nano-hydroxyapatite can calcify the pineal gland, so we avoid it in all of our formulations. This recipe contains calcium bentonite clay, hydroxyapatite powder, di-calcium phosphate, diatomaceous earth, baking soda, calcium carbonate, sage leaf, Himalayan salt, maca, lucuma, activated charcoal and turmeric powder. All ingredients are organic, food-grade and NON-GMO. This product is NOT vegan like most of our others because of the hydroxyapatite. We can customize this product upon request (and sometimes an additional fee) with a higher percentage of hydroxyapatite or to omit/replace some of the ingredients.
