Verified Jun 20, 2026
This is a powdered kidney support supplement for cats that combines herbal ingredients like astragalus and rehmannia with cordyceps, chitosan, and a specialized Syntek probiotic blend. It’s designed to be given alongside your cat’s regular diet to help support kidney filtration and overall kidney function. The powder can be sprinkled over wet food, which makes it easier for many cats to accept.
This supplement offers a thoughtful blend of herbs, chitosan, and targeted probiotics aimed at supporting kidney function in cats, and it’s easy to give by mixing with wet food. It’s best used as an adjunct to a complete and balanced kidney-friendly diet under your veterinarian’s guidance.

At a Glance
KibbleLab Review
Strengths
- Uses multiple kidney-supportive ingredients, including astragalus, rehmannia, cordyceps, and chitosan, which are commonly used in integrative veterinary medicine for renal support.
- Includes a dedicated Syntek kidney health probiotic blend with multiple Lactobacillus strains, providing 5 billion CFU per serving for gut and immune support, which can be helpful in cats with chronic conditions.
- Powder form that can be sprinkled over wet food, which is usually more acceptable to cats than tablets or capsules and allows flexible dosing.
- Manufactured in the USA in an FDA-registered GMP facility and NASC certified, which supports good quality-control practices for a supplement product.
Considerations
- This is a supplement, not a complete and balanced diet, so it should always be used in addition to an appropriate cat food, especially a veterinary kidney diet if your cat has diagnosed kidney disease.
- Contains chicken bone broth, so it is not suitable for cats with chicken allergies or strict protein restrictions requiring non-chicken formulations.
- Herbal and nutraceutical ingredients like astragalus, rehmannia, and cordyceps may not be appropriate for every cat; it’s important to review this with your veterinarian, particularly if your cat is on other medications or has advanced disease.
- Kittens or very young cats with kidney issues should only receive this under direct veterinary supervision, as the formula was primarily designed with adult and senior cats in mind despite multi-stage labeling.

Top 5 Ingredients Explained
01
Astragalus
Astragalus is an herbal botanical used in pet foods and supplements as an immune-supporting ingredient and antioxidant rather than a macronutrient; its root contains polysaccharides and flavonoids that are thought to have adaptogenic and immune-modulating effects for dogs and cats. Evidence in companion animals is limited, so benefits are modest and product quality varies; caretakers should be aware of possible gastrointestinal upset, allergic reactions, and interactions with immunosuppressive or anticoagulant medications and consult their veterinarian before use.
02
Cordyceps
Cordyceps is a medicinal mushroom often included in pet foods or supplements as a functional ingredient rather than a primary nutrient, marketed for its antioxidant properties and potential to support energy, respiratory function, and immune health in dogs and cats. Evidence in companion animals is limited, so benefits are not guaranteed; quality and dosing vary between products and there can be risks of gastrointestinal upset or interactions with medications (for example immunosuppressants or blood thinners), so consult your veterinarian before use, especially for pregnant, nursing, or medicated pets.
03
Rehmannia
Rehmannia is a traditional Chinese herbal botanical sometimes included in pet foods or supplements as a functional ingredient or “tonic,” used for its purported support of kidney/adrenal health, immune function and mild anti-inflammatory effects rather than as a source of protein, fat or vitamins. Scientific evidence in dogs and cats is limited and benefits are largely extrapolated from human or laboratory studies, so there are considerations around product quality, possible herb–drug interactions and gastrointestinal sensitivity; use should be guided by a veterinarian, especially in pregnant animals or pets on medication.
04
Chitosan
Chitosan is a deacetylated derivative of chitin used in pet foods as a non-digestible fiber and fat‑binding agent to support weight management, reduce fat absorption, and sometimes improve stool quality or act as a natural antimicrobial/chelating additive. It provides minimal calories and may modestly lower lipid absorption in dogs and cats, but can interfere with absorption of fat‑soluble vitamins and certain medications and is typically derived from shellfish, so products should be used cautiously in animals with shellfish sensitivity and under veterinary guidance.
05
SYNTEK Kidney Health Probiotic
SYNTEK Kidney Health Probiotic is a live microbial supplement formulated to support the gastrointestinal microbiome and is used as an adjunct in pet diets to help reduce gut‑derived uremic toxins that can contribute to kidney workload in dogs and cats. It may support digestive health and complement veterinary care for chronic kidney concerns, but efficacy can vary, it is not a replacement for medical treatment, and owners should follow manufacturer dosing and consult their veterinarian—particularly for immunocompromised animals or pets on multiple medications.
