Phosclear from vivaldis acts as phosphorus binder which helps excrete unwanted phosphorus from dogs & cats suffering from CKD. This is because mostly dogs with CKD (Chronic kidney disease / renal failure) are unable to excrete excess phosphorus resulting in elevated serum phosphate. It acts as Phosphatemia management, a solution to nip hyperparathyroidism in the bud. Helps support normal and healthy function of kidneys. Professional veterinary formula.
