Catzymes Kidney Support Powder Supplement
Verified Jun 20, 2026
This is a powdered kidney-support supplement for cats that combines active dry yeast, multiple probiotic cultures, prebiotic FOS, and hydrolyzed Alaskan salmon with added vitamins, minerals, and turmeric. It’s designed to be given with meals to help support overall kidney health, digestion, and general vitality, particularly in aging cats or those with kidney concerns. Because it’s a supplement rather than a complete diet, it’s intended to be used alongside your cat’s regular, balanced food.
Nutritionally, this is a fairly sophisticated supplement with a wide range of probiotics, prebiotics, vitamins, and kidney-focused add-ins like cranberry and turmeric, which can complement the diet of cats with kidney issues or seniors in general. The use of hydrolyzed fish protein should make it easier to digest and less likely to trigger food reactions compared with whole fish proteins. It’s best suited for cats already on a veterinarian-recommended, complete kidney-friendly diet, as an adjunct rather than a standalone solution.

At a Glance
KibbleLab Review
Strengths
- Includes multiple probiotic strains plus prebiotic FOS, which together can help support a healthy gut microbiome and digestion.
- Contains hydrolyzed Alaskan salmon powder, providing a highly digestible protein source with reduced risk of triggering typical fish sensitivities.
- Provides a broad blend of vitamins and trace minerals (including selenium, cobalt, zinc, manganese) to help fill potential micronutrient gaps in the diet.
- Includes turmeric, cranberry pulp, yucca, and alfalfa, which offer additional phytonutrients and may support urinary and overall health in a complementary way.
Considerations
- This is a supplement, not a complete and balanced diet, so it should always be used alongside an appropriate full cat food, especially for cats with kidney disease.
- Contains egg yolk powder, whey, and soybean oil, which may be problematic for cats with known allergies or intolerances to egg, dairy, or soy.
- Active dry yeast and yeast culture are prominent ingredients; while generally safe, a small number of cats may experience digestive upset or yeast sensitivity and should be monitored when starting this product.
- Any cat with suspected or diagnosed kidney disease should be under veterinary care, and the amount used may need to be adjusted based on your veterinarian’s guidance.

Top 5 Ingredients Explained
01
Active Yeast
Active yeast is used in pet food as a live yeast/probiotic and palatability enhancer, supplying protein, B‑vitamins, beta‑glucans and mannan oligosaccharides that can support digestion, healthy gut microbes and immune function in dogs and cats. While generally safe, it can trigger reactions in animals with yeast sensitivities and should be used with caution or under veterinary guidance for immunocompromised pets or animals with conditions affected by purine intake or urinary stone history.
02
Ascorbic Acid
Ascorbic acid is the chemical form of vitamin C commonly used in pet foods as an antioxidant and preservative to protect fats, flavors, and other vitamins from oxidation and sometimes included as a supplemental source of vitamin C. Dogs and cats generally synthesize vitamin C endogenously so it is not essential in most diets, but added ascorbic acid can support immune function and wound healing and help stabilize the product; large supplemental doses can cause gastrointestinal upset or increase urinary oxalate in susceptible animals, so extra supplementation should be guided by a veterinarian.
03
Alpha-Tocopherol
Alpha-tocopherol is the biologically active form of vitamin E commonly added to pet foods both as an essential fat‑soluble vitamin and as an antioxidant/preservative to protect fats and fat‑soluble nutrients from rancidity. It helps protect cells and supports immune, skin and coat health in dogs and cats; deficiency is uncommon except with fat‑absorption problems, and supplementation should follow recommended levels since very high doses can potentially affect blood clotting and should be balanced with other nutrients like selenium.
04
Biotin
Biotin (vitamin B7) is a water‑soluble vitamin added to pet foods as a micronutrient to support energy metabolism and healthy skin, coat, and paw pad integrity in dogs and cats. Deficiencies are uncommon with commercial diets but supplementation can help with dermatitis or poor coat quality—biotin is generally safe at recommended levels, though therapeutic or high‑dose use should be done under veterinary guidance and raw egg whites can interfere with biotin absorption.
05
Choline Chloride
Choline chloride is an essential nutrient commonly added to pet foods as a concentrated source of choline, which supports cell membrane structure, acetylcholine neurotransmitter production, liver function and normal fat metabolism. It is important for growth, reproduction and preventing fatty liver in dogs and cats; deficiencies are rare in complete diets but manufacturers include it in vitamin/mineral premixes, while diets should balance choline with other methyl donors and handle the hygroscopic nature of the ingredient during processing.
