What Is PhosAvast™?
Supporting normal levels of phosphorus is important to kidney health in cats and dogs. PhosAvast™ is a veterinarian-developed supplement that captures dietary phosphorus in the gut to reduce the amount needed to be processed by the kidneys. Its proprietary blend of three phosphate-binding ingredients provides broader coverage than single-ingredient alternatives.
- Binds dietary phosphorus in the gut, forming an insoluble compound eliminated naturally in the feces.
- Reduces phosphorus burden on kidneys.
- Promotes kidney health by reducing the amount of phosphorus processed by the kidneys.
- Works with all diets, including commercial, vet-recommended renal, and home-prepared.
Three Binders. One Capsule
Most phosphate binders rely on a single ingredient. PhosAvast combines three, each working through a different mechanism, to support normal phosphorus levels:
Calcium Carbonate
A mineral-based binder that captures phosphorus directly in the intestines before absorption
Chitosan
A naturally derived polysaccharide that provides a complementary, non-mineral binding pathway
Magnesium Carbonate
A calcium-free mineral binder that broadens phosphate capture without adding dietary calcium
Together, these three pathways mean more phosphorus is captured in the gut and less reaches the kidneys.
Research-Backed Kidney Support
Peer-reviewed research shows that managing phosphorus levels can support the overall health and well-being of cats and dogs as they age. PhosAvast has been shown to lower phosphorus, a key marker veterinarians track to measure healthy kidney function.
Simple to Administer
PhosAvast comes in a palatable sprinkle capsule for easy administration. Simply open the capsule and sprinkle over your pet’s food at mealtime. PhosAvast is safe for long-term use and can be given alongside other supplements and medications for as long as your pet needs it.
