The invention provides a method for the production of a zeolite particle composition which has optimized characteristics, such as enhanced adsorption and specific ion exchange properties. A method and an apparatus for producing improved zeolite particle compositions are provided, where the particles are treated with an oxygen-containing gas during micronisation. The zeolite particle compositions can be used in a method for treatment of the human or animal body by therapy and/or prophylaxis, and specifically in a method of treating or preventing conditions of the human or animal body or symptoms of these conditions that are related to heavy metals, endotoxins, exotoxins, and/or bacterial, viral or parasitic intoxications in or of the digestive system, mucosal surfaces or the skin. Also, new zeolite particle compositions can be used as food additive, as filter for purification of water, in packaging materials, or as cosmetic ingredient.
