Catzymes Liver Support Powder Supplement
Verified Jun 7, 2026
This is a liver-support supplement powder for cats that combines choline, milk thistle, probiotics, and digestive enzymes. It’s designed to be sprinkled on meals to support liver metabolism, gut health, and overall digestion alongside a regular complete diet. The formula also includes prebiotics, yeast, and yucca extract, which can further support the intestinal environment and detox pathways.
Nutritionally, this is a thoughtfully designed liver-support supplement that targets both liver function and digestive health using choline, milk thistle, multiple probiotic strains, and digestive enzymes. It’s best used as an add-on to a complete and balanced cat food, particularly for cats where your veterinarian has recommended extra liver or digestive support. Overall, the ingredient profile is solid for a supplement, but it should always be used under veterinary guidance, especially for cats with known liver or metabolic disease.

At a Glance
KibbleLab Review
Strengths
- Includes choline chloride, which plays an important role in fat metabolism and normal liver function in cats.
- Contains milk thistle seed, a widely used botanical for liver support thanks to its antioxidant properties.
- Uses a broad-spectrum probiotic blend (multiple Lactobacillus, Bifidobacterium, Enterococcus, and Bacillus strains) plus prebiotic fructooligosaccharides to support a healthy gut microbiome.
- Provides digestive enzyme sources from Aspergillus and Trichoderma fermentation extracts, which can help cats digest and absorb nutrients more efficiently from their regular food.
Considerations
- This is a supplement only and does not provide complete and balanced nutrition, so it must be given together with a regular cat diet, not as a main food.
- Contains dairy-derived ingredients (dried whey) and yeast, which may not suit cats with known sensitivities to these components.
- Any liver-support product for a cat with existing liver disease, pancreatitis, or other chronic illness should be used under veterinary supervision to ensure it’s appropriate and dosed correctly.
- The powder relies on palatability from ingredients like dextrose and yeast; some very picky cats may still resist it when mixed with food, so owners may need to introduce it gradually.

Top 5 Ingredients Explained
01
Calcium Carbonate
Calcium carbonate is a common mineral supplement and buffering agent in pet foods used to provide dietary calcium, help meet calcium-to-phosphorus balance, and stabilize pH. It supports bone and dental health and is essential for growth, reproduction, and metabolic functions, but excessive calcium (or imbalanced calcium/phosphorus ratios) can cause skeletal problems in growing animals—especially large-breed puppies—so it should be included at appropriate levels determined by a qualified formulation.
02
Calcium Propionate
Calcium propionate is a calcium salt used primarily as a preservative and antifungal agent in pet foods and treats to inhibit mold growth and extend shelf life; it contributes only a negligible amount of calcium nutritionally. It is generally recognized as safe for dogs and cats at approved levels and helps reduce the risk of mycotoxin contamination, though very large amounts or sensitivities can cause gastrointestinal upset, so manufacturers adhere to regulatory limits.
03
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.
04
Copper Proteinate
Copper proteinate is an organic, chelated source of the trace mineral copper used in pet foods to provide a bioavailable copper supplement that supports enzyme function, connective tissue and bone formation, iron metabolism, and healthy skin and coat in dogs and cats. Because copper is required only in small amounts, this form is often preferred for better absorption compared with inorganic salts, but diets must be carefully balanced to avoid excess (and some breeds with copper storage disorders are especially sensitive) and to maintain proper ratios with other minerals like zinc and molybdenum.
05
Aspergillus Niger Fermentation Extract
Aspergillus niger fermentation extract is a fermentation-derived additive used in pet foods to provide enzymes or organic compounds that can improve digestibility, nutrient availability (for example by helping break down starches or phytates), and sometimes palatability. It is not a primary nutrient for dogs or cats, and when produced to food-grade standards it is generally considered safe, though care is taken to ensure the product is free of contaminants and animals with rare sensitivities to fungal proteins could potentially react.
