Boka's first official kid's flavor, Orange Cream, has vibrant notes of oranges paired with creamy natural vanilla. The name, Space Paste, is a nod to NASA's invention of nano-hydroxyapatite (nHa) in the 1970's. The ingredient, once only enjoyed exclusively by astronauts, is now available to our junior space voyagers. Orange Cream, like our other flavors, trades fluoride for nano-hydroxyapatite (n-Ha), an evolution in dentistry that’s been a gold standard in Japan for over 40-years. n-Ha makes up the primary foundation of teeth and bones, meaning it’s naturally restorative and helpful in reducing sensitivity. Plus, it’s 100% biocompatible and non-toxic.
