Zeolite or Clinoptilolite in its powdered form and without nano-particles is neither digested nor absorbed into the bloodstream. The Zeolite itself plus the captured toxins are eliminated by bowel movement. Cations such as Silica, Calcium, Magnesium, Potassium, Sodium, Iron are exchanged for noxious chemicals (inhaled or ingested), poisonous heavy metals, free radicals (e.g. formed by stress), bacterial or viral particles, myco-toxins (from fungi), radiation (X-ray, cosmic radiation) and nuclear radioelements.
So why not use Zeolite?
