Liver Support Powder Supplement for Dogs and Cats
Verified Jun 17, 2026
This is a liver support powder supplement for dogs and cats that combines milk thistle extract, turmeric curcumin, N-acetylcysteine, and several herbs with added antioxidants like vitamins C and E and zinc. It’s designed to be given alongside a complete diet to help support normal liver function and detoxification processes in pets of any age. The chicken bone broth flavor is intended to make it easier to mix into your pet’s regular food.
As a liver support supplement, this formula uses several well-known ingredients for hepatic and antioxidant support, including a standardized milk thistle extract, turmeric curcumin, NAC, vitamin C, vitamin E, and zinc. It’s suitable for both dogs and cats and is meant to be used in addition to a nutritionally complete diet, not as a primary food. This can be a reasonable option for owners working with their veterinarian on extra liver support, as long as it fits into the pet’s overall medical plan.

KibbleLab Review
Strengths
- Contains a standardized milk thistle extract (80% silymarin), which is one of the more studied herbal supports for liver function in pets and people.
- Includes multiple antioxidant and liver-related nutrients such as turmeric curcumin, N-acetylcysteine (NAC), vitamins C and E, zinc, and choline, which together may help support normal liver and immune function.
- Formulated for both dogs and cats, which can be convenient for multi-pet households, and provided in a powder that can be mixed with food for easier administration.
- Uses chicken bone broth for palatability rather than artificial flavors, and avoids added colors or sweeteners.
Considerations
- This is a supplement only and does not provide complete and balanced nutrition, so it must be used together with a full diet, ideally under veterinary guidance—especially for pets with known liver disease or those on other medications.
- Contains chicken bone broth, so it is not appropriate for pets with chicken allergies or those on strict elimination diets.
- Herbal and nutraceutical ingredients like turmeric, burdock, dandelion, and artichoke can interact with some medications or health conditions; your veterinarian should review this formula before use in pets with complex medical histories.
- Powdered supplements can be difficult to dose precisely for very small pets without clear weight-based dosing directions from the manufacturer or your veterinarian.

Top 5 Ingredients Explained
01
Milk Thistle
Milk thistle is an herbal supplement used in some pet foods and supplements for its liver-supporting and antioxidant properties, with the active component silymarin thought to help protect liver cells and support detoxification. It is a supportive, non-essential ingredient rather than a nutrient, so pet owners should consult a veterinarian before use because effectiveness can vary by product and dosage, and it may interact with medications or cause mild gastrointestinal upset or allergic reactions in some animals.
02
Curcumin C3 Complex
Curcumin C3 Complex is a standardized curcuminoid extract derived from turmeric used in pet foods and supplements primarily for its antioxidant and anti‑inflammatory properties to support joint comfort, immune health, and help reduce oxidative stress in dogs and cats. Because curcumin has low natural bioavailability, products often include enhancements for absorption; owners should be aware of limited but promising evidence in companion animals, possible gastrointestinal upset, and potential interactions with anticoagulant or other medications, so consult a veterinarian for appropriate dosing and use in pregnant, nursing, or gallbladder‑diseased pets.
03
N-Acetyl-L-Cysteine
N‑Acetyl‑L‑Cysteine (NAC) is used in veterinary nutrition and medicine as an antioxidant and glutathione precursor, sometimes added as a supplement to support liver detoxification and to help break down respiratory mucus. It can provide hepatoprotective and antioxidant benefits in dogs and cats (and is the established antidote for acetaminophen toxicity in cats), but should be used under veterinary guidance because improper dosing can cause gastrointestinal upset and other adverse effects.
04
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.
05
Choline
Choline is an essential nutrient commonly added to pet foods (often as choline chloride) that supports neurotransmitter synthesis (acetylcholine), fat transport and liver health, and serves as a methyl-group donor in metabolism. It is important for brain development, cognition and reproductive health in dogs and cats; deficiency can contribute to fatty liver and poor growth, while supplementation is generally safe though very high doses may cause mild gastrointestinal upset and the choline chloride form is hygroscopic, which can affect processing.
