Overview

Rx Edible Clay Powder is a 3.52 oz powder supplement from Rx Vitamins aimed at digestive support in cats and dogs, marketed for easing diarrhea, constipation and gas.

Edible clay is a traditional digestive aid rather than a novel formulation, typically mixed into food to bind loose stool and settle an upset gut. Because it targets both looser and firmer stool complaints, it is positioned as a general digestive-support product rather than one condition specifically.

Who it's for
