Zeolite comes from volcanic rock. Its structure is full of microscopic pores that act like tiny cages. People take it as a powder stirred into water or as capsules.
Because those pores can trap substances in the gut, take zeolite on an empty stomach. A good rhythm is at least one hour before or two hours after other supplements and medications. This spacing helps avoid unwanted binding.
Some people notice mild stomach upset or constipation. Drink plenty of water while using it.
