Available in 90g and 300g jars
The kidneys are essential organs responsible for removing waste products, regulating blood pressure, controlling calcium metabolism, and stimulating red blood cell production. Unlike the liver, kidney tissue cannot regenerate once it is lost. Because pets have millions of nephrons across two kidneys, significant kidney damage can occur before any abnormalities show up on blood or urine tests — which is why early detection and ongoing management are so critical.
Chronic kidney disease (CKD) is one of the most common conditions in aging dogs and cats. While acute kidney disease may be reversible with rapid treatment, CKD requires long-term management to help your pet live as comfortably as possible for as long as possible.
Aventi Kidney Complete is the most comprehensive nutritional kidney support supplement available in Canada. Rather than addressing only one aspect of kidney failure, it is formulated to counteract each major metabolic consequence of CKD in a single, easy-to-give powder.
The formula works on five fronts simultaneously. Phosphate binders (calcium carbonate, calcium lactate gluconate, and chitosan) help reduce excess phosphorus that damaged kidneys can no longer filter effectively — elevated phosphorus is one of the primary drivers of CKD progression. Sodium bicarbonate buffers metabolic acidosis, following IRIS (International Renal Interest Society) guidelines, helping to stabilize blood pH and slow muscle wasting. Prebiotics (FOS) and probiotics (Lactobacillus acidophilus and L. plantarum) act as blood cleansers by metabolizing uremic toxins in the gut, reducing the toxic load the kidneys must handle. B vitamins (B6, B9, B12) and Vitamin C support red blood cell production, addressing the anemia that commonly accompanies kidney disease. Antioxidant support from chitosan, vitamin C, and olive oil extract helps protect remaining kidney tissue from oxidative damage.
Aventi Kidney Complete is exclusively available through veterinary clinics and comes in 90g or 300g jars with both a 0.6g small scoop and 2.4g large scoop included for accurate dosing across all pet sizes.
Key Ingredients:
Calcium carbonate (156 mg per 0.6g scoop) — Binds dietary phosphorus in the gut, preventing absorption and reducing the phosphorus burden on failing kidneys.
Calcium lactate gluconate (96 mg) — A secondary phosphate binder that works alongside calcium carbonate for more complete phosphorus control.
Chitosan (48 mg) — A natural phosphate binder derived from shellfish that also provides antioxidant properties.
Sodium bicarbonate (36 mg) — Buffers metabolic acidosis, a common complication of CKD. This is the IRIS-recommended approach to managing blood pH in kidney patients.
Fructooligosaccharides / FOS (120 mg) — A prebiotic fibre that feeds beneficial gut bacteria and supports the metabolism of uremic toxins.
Lactobacillus acidophilus (180 million CFU) & L. plantarum (60 million CFU) — Probiotic strains that help break down uremic toxins in the gut, effectively reducing the workload on damaged kidneys.
Vitamins B6 (3 mg), B9 (1.2 mg), B12 (0.06 mg) — Support red blood cell metabolism, addressing CKD-related anemia.
Vitamin C (30 mg) — Antioxidant support and contributes to red blood cell health.
Olive oil extract (12 mg) — Provides additional antioxidant protection for remaining kidney tissue.
Directions for Use:
Administer daily by mixing powder into food.
Small scoop (0.6g): 1 level scoop per 2.5 kg of body weight. Large scoop (2.4g): 1 level scoop per 10 kg of body weight.
Examples: A 5 kg cat gets 2 small scoops daily. A 20 kg dog gets 2 large scoops daily. A 30 kg dog gets 3 large scoops daily.
What makes Aventi Kidney Complete stand out is that it addresses all five metabolic consequences of CKD in a single product. Most kidney supplements focus only on phosphate binding or only on probiotics — pet owners end up juggling three or four separate products. Aventi combines phosphate binders, an IRIS-recommended bicarbonate buffer, uremic toxin-metabolizing probiotics, blood-building B vitamins, and antioxidant protection into one powder. The inclusion of sodium bicarbonate is particularly noteworthy — metabolic acidosis accelerates muscle wasting and CKD progression, yet most over-the-counter kidney supplements ignore it entirely. If your pet has been diagnosed with CKD at any stage, this is the most complete single supplement you can add to their management plan.
FAQ Accordion:
Q: At what stage of kidney disease should I start using this? A: Aventi Kidney Complete is formulated for all stages of chronic kidney disease. Earlier use helps manage phosphorus levels and metabolic acidosis before they cause further damage. Your veterinarian can guide you on when to begin based on your pet's blood work.
Q: Can I use this alongside a prescription kidney diet? A: Yes, Aventi Kidney Complete is designed to complement prescription kidney diets like Hill's k/d or Royal Canin Renal. The phosphate binders and probiotics provide additional support beyond what diet alone can achieve. Always confirm with your veterinarian.
Q: How do I give the powder to a picky eater? A: The powder is flavourless and mixes easily into wet food. For picky pets, try mixing it into a small amount of their favourite wet food or a treat paste to ensure they consume the full dose before offering the rest of their meal.
Q: How long should my pet stay on this supplement? A: Chronic kidney disease requires long-term management. Most pets with CKD stay on kidney support supplements indefinitely, with dosing adjustments based on ongoing blood test results and veterinary guidance.
Q: What is the difference between the 90g and 300g jars? A: Same formula, different sizes. The 300g jar is more economical for larger dogs or long-term use. For a 5 kg cat taking 2 small scoops (1.2g) daily, a 90g jar lasts approximately 75 days. For a 20 kg dog taking 2 large scoops (4.8g) daily, a 300g jar lasts approximately 62 days.
Q: Is Aventi Kidney Complete safe for cats? A: Yes, it is formulated for both dogs and cats. CKD is especially common in senior cats, and the dual scoop system makes it easy to dose accurately for smaller patients.
