NuFeed® is sourced from natural zeolite deposits south of Rotorua in New Zealand’s central north island. 250,000 years ago, vigourous volcanic activity deposited these Zeolites in lakebed sediments. In the presence of hot water (120°C), the clays became soft rocks with organized internal structure sequences. They behave differently from other zeolites mined in other regions of NZ, Australia, USA, and Europe due to their geological youth.
