In 2015 after 18 months of researching, testing and refining, Grin Natural was born! Not only is Grin toothpaste missing all the nasties, it’s natural active ingredients; Manuka Oil, Propolis and Organic Sea Salt, based on Grin’s laboratory test results, show good potential to combat the six common oral bacteria. Today, Grin Natural is stocked in over 600 retailers in New Zealand, including dental clinics nationwide - so you too can get grinning!
