Editing Zeolite (section)

===Veterinary and human use===
Zeolites have some veterinary applications, with [[clinoptilolite]] approved in the EU as an additive for cattle feed.<ref>{{cite journal |title=Scientific Opinion on the safety and efficacy of clinoptilolite of sedimentary origin for all animal species: Clinoptilolite of sedimentary origin for all animal species |journal=EFSA Journal |date=January 2013 |volume=11 |issue=1 |pages=3039 |doi=10.2903/j.efsa.2013.3039}}</ref> It acts primarily as a detoxifying agent in the gut, where is can absorb undesirable species via ion-exchange before being excreted. For instance, nitrate fertilisers are water soluble and prolonged exposure by dairy cattle is known to impair protein metabolism and glucose utilization. Clinoptilolite adsorbs nitrate ions with good selectivity, allowing it to reduce these ill effects.<ref>{{cite journal |last1=Katsoulos |first1=P. D. |last2=Karatzia |first2=M.

Regardless, they are widely marketed as [[dietary supplements]].
