Support your cat or dog’s kidney health with Pronefra® Oral Suspension, a highly palatable liquid renal support supplement designed for adult cats and dogs requiring nutritional support for kidney function and healthy blood phosphorus levels.
Pronefra® combines Calcium Carbonate, Magnesium Carbonate, Chitosan and Marine Oligopeptides (Fish Protein Hydrolysate) to provide multi-action nutritional support.
The formula works within the digestive tract to help bind dietary phosphate and uraemic waste products, while marine oligopeptides provide additional support for maintaining balanced blood pressure.
Its liquid format makes Pronefra® particularly convenient for cats and dogs that dislike tablets or capsules. It can be mixed directly with food or administered into the mouth using the included dosing syringe.
Ideal for adult cats and dogs requiring additional nutritional support as part of a comprehensive kidney-care programme, particularly when maintaining appropriate phosphate levels is an important consideration.
Why You’ll Love It
Supports Healthy Kidney Function
Kidneys play an essential role in filtering waste products and maintaining the body’s mineral and fluid balance.
When kidney function becomes compromised, certain substances such as phosphate and uraemic waste products can accumulate.
Pronefra® provides nutritional support through several complementary mechanisms, helping reduce the digestive absorption of substances that may otherwise place additional demands on compromised kidney function.
Helps Control Dietary Phosphate Absorption
Maintaining appropriate phosphorus levels is an important part of nutritional management for pets with reduced kidney function.
Calcium Carbonate and Magnesium Carbonate act as phosphate-binding ingredients within the digestive tract.
They bind dietary phosphate and reduce its availability for absorption, helping support healthy blood phosphorus levels.
This makes Pronefra® particularly useful alongside an appropriate veterinary renal diet where additional phosphate management may be required.
Supports the Management of Uraemic Waste Products
Pronefra® contains Chitosan, a functional biopolymer that works within the digestive tract.
Chitosan can bind certain uraemic waste products, including compounds associated with protein breakdown, helping reduce their absorption and supporting the body’s overall waste-management processes.
This provides an additional layer of nutritional support for pets with compromised renal function.
Helps Maintain Balanced Blood Pressure
Healthy blood pressure is an important part of maintaining kidney wellbeing.
Pronefra® contains Marine Oligopeptides, also known as fish protein hydrolysate.
These naturally derived peptides provide nutritional support for maintaining balanced blood pressure, which is particularly relevant when supporting pets with compromised kidney function.
Multi-Action Renal Support in One Formula
Pronefra® brings together several functional ingredients to provide comprehensive nutritional support:
- Calcium Carbonate – binds dietary phosphate
- Magnesium Carbonate – contributes additional phosphate-binding support
- Chitosan – binds certain uraemic waste products within the intestine
- Marine Oligopeptides – support balanced blood pressure
This combination provides a broader approach to nutritional kidney support than relying on a single functional ingredient.
Easy Liquid Administration
Cats can be notoriously difficult to medicate, particularly when tablets or capsules are involved.
Pronefra® is supplied as a palatable liquid suspension that can be incorporated directly into food or administered orally using the supplied dosing syringe.
This makes daily administration simple and flexible.
It is particularly useful for pets that:
- Refuse tablets
- Dislike capsules
- Are difficult to medicate
- Prefer liquid supplements
- Need daily nutritional support
- Are already receiving a veterinary renal diet
Highly Palatable and Easy to Accept
Pronefra® has been developed as a tasty liquid formulation to make regular administration easier for both pets and their owners.
The liquid can be mixed with food, helping avoid the need to force tablets or capsules.
For pets that accept direct oral administration, the included syringe provides another convenient option.
Functional Ingredients with Real Purpose
Calcium Carbonate – Phosphate Binding Support
Calcium Carbonate is an inorganic mineral salt with phosphate-binding properties.
When administered with food, it can bind dietary phosphate within the intestine, reducing its availability for absorption.
This helps support nutritional phosphorus management in cats and dogs requiring kidney support.
Magnesium Carbonate – Additional Phosphate Binding
Magnesium Carbonate works alongside Calcium Carbonate as an additional phosphate-binding ingredient.
Together, these mineral salts help reduce the amount of dietary phosphate available for intestinal absorption.
This combination is particularly relevant for animals where maintaining healthy blood phosphorus levels is an important part of renal nutritional management.
Chitosan – Uraemic Waste Binding Support
Chitosan is a functional biopolymer included to help bind certain uraemic waste products within the gastrointestinal tract.
By binding these compounds in the intestine, Chitosan can help reduce their availability for absorption.
This provides additional nutritional support for pets whose kidneys have reduced ability to eliminate metabolic waste.
Marine Oligopeptides – Blood Pressure Support
Marine Oligopeptides, also known as Fish Protein Hydrolysate, are naturally derived peptides obtained from hydrolysed fish protein.
These peptides provide nutritional support for maintaining balanced blood pressure.
Balanced blood pressure is particularly important when supporting overall kidney health.
How It Works
Pronefra® provides renal nutritional support through several complementary actions.
When administered around mealtimes, Calcium Carbonate and Magnesium Carbonate bind dietary phosphate in the digestive tract, helping reduce the amount available for absorption.
At the same time, Chitosan binds certain uraemic waste products, helping reduce their absorption from the intestine.
Marine Oligopeptides provide additional nutritional support for maintaining balanced blood pressure.
Together, these actions help support healthy kidney function and contribute to a comprehensive nutritional approach for adult cats and dogs requiring renal support.
Pronefra® is not intended to replace veterinary treatment or a prescribed renal diet. It should be used as part of an appropriate kidney-care programme.

Pronefra® may provide useful nutritional support for adult pets when:
- Kidney function requires additional nutritional support
- Dietary phosphate management is important
- Blood phosphorus levels need to be carefully managed
- A pet requires additional support alongside a veterinary renal diet
- Tablet administration is difficult
- A liquid supplement is easier to administer
- Additional support for uraemic waste management is desired
- Maintaining balanced blood pressure is part of the overall kidney-care strategy

Pet parent review
“The liquid format made kidney support much easier for my cat. I can mix it into his food instead of trying to give him another tablet, and the included syringe makes measuring the dose straightforward.” Margaret H.
Veterinary Advice
Kidney disease is a complex condition that requires individualised management.
If your cat or dog has been diagnosed with kidney disease, we strongly recommend regular veterinary check-ups and appropriate blood and urine monitoring.
Your veterinarian can assess kidney function, phosphorus levels, blood pressure, hydration and nutritional status and determine whether Pronefra® is appropriate for your pet.
Always consult your veterinarian before giving Pronefra®, particularly if your pet is taking medication, following a prescribed renal diet, has advanced kidney disease, or has other underlying health conditions.
Do not change, stop or replace prescribed veterinary treatment without professional advice.
