Yes, Epakitin is a phosphate binder. The Epakitin nutritional supplement contains chitosan. The chitosan is what helps bind the phosphates. That in turn can control the amount of phosphorus that can be absorbed by the pet’s intestines. Limiting the amount of phosphorus is a very popular method to maintain and support the body’s normal kidney functioning. Epakitin uses this approach to ensure the same for your cats and dogs.
