Advanced TRS is different in many ways: Through Coseva’s proprietary processes, the zeolite particle is nano-sized and stabilized in water which allows it to be easily assimilated. Additionally, Advanced TRS is the purest form of clinoptilolite available because it is Lab Grown in a clean laboratory facility, using state of the art technology and science.The Lab Grown zeolite in Advanced TRS is an improvement on nature since its synthesis occurs from only well-characterized precursors, in a clean, sterile environment.
