Review on 🌱 Ultra Fine Zeolite Powder 1 Pound - 20 µm, 90-92% Clinoptilolite, Activated Natural Mineral Dust by Heiltropfen by Sarah Richards

Several reviews have raised concerns about dangerous levels of lead and aluminum. Apparently the warnings apply to other zeolite sources and not this one. Please see manufacturer's analysis for this Revain listing. They are far from the levels mentioned in these few well-intentioned reviews. If you're concerned, find someone who can check their test results, which I've copied below: MINERALOGICAL COMPOSITION Clinoptilolite 90-92%, Feldspar 2-4%, Cristobalite 5-7%, Mica 1-2% CHEMICAL COMPOSITION SiO2 65 .0 to 71.3% Al2O3 11.5 to 13.1% CaO 2.7 to 5.2% K2O 2.2 to 3.4% Fe2O3 0.7 to 1.9% MgO 0.6 to 1, 2% Na2O 0.2 to 1.3% TiO2 0.1 to 0.3% Trace element analysis: Co <3 ppm Cu 3 ppm Sn < 1 ppm Pb 10 ppm As 0.8 ppm Cd < 0.1 ppm Hg 0.021 ppm Si/Al 4.8-5.4ppm
