Cardiac Support Supplement for Dogs and Cats
Verified Jun 9, 2026
This is a low-calorie, salmon-flavored cardiac support supplement in a vegan capsule for dogs and cats. It provides taurine, L-carnitine, CoQ10, vitamin E, and organic hawthorn berry, nutrients commonly used to support heart and circulatory function. The powder can be given in the capsule or sprinkled on food, which is especially handy for cats or picky pets.
This is a thoughtfully formulated heart-support supplement that combines taurine, L-carnitine, CoQ10, vitamin E, and hawthorn berry in very low-calorie capsules suitable for both dogs and cats. It’s not a complete diet, but it can be a reasonable adjunct for pets where a veterinarian has recommended additional cardiac-focused nutrients. As with any heart supplement, it’s best used under veterinary guidance, especially for pets already on heart medications or with diagnosed cardiac disease.

At a Glance
KibbleLab Review
Strengths
- Includes taurine and L-carnitine, two amino-acid–related nutrients that are commonly used to support heart function in both dogs and cats.
- Provides CoQ10 and vitamin E, which act as antioxidants and can help support normal cellular and heart muscle function.
- Contains organic hawthorn berry, a botanical frequently used in cardiac-support formulations for circulatory support.
- Very low calorie per capsule and can be given whole or opened and sprinkled, which offers flexibility for small dogs and cats.
Considerations
- This is a supplement, not a complete and balanced food, so it should be used in addition to a nutritionally complete diet rather than as a replacement for any part of the diet.
- Heart supplements can interact with prescription heart medications or may not be appropriate for all cardiac conditions, so it’s important to review this product and its exact dosages with your veterinarian before starting.
- Contains salmon flavor, which may not be suitable for pets with fish allergies or those on strict prescription elimination diets.

Top 5 Ingredients Explained
01
Taurine
Taurine is an amino sulfonic acid added to pet foods to support essential functions such as heart muscle performance, retinal health, and reproduction, and is particularly critical for cats, which cannot synthesize enough on their own. Adequate taurine prevents conditions like dilated cardiomyopathy and vision degeneration—dogs generally make more taurine but certain breeds or homemade/vegetarian diets may require supplementation—so commercial diets should meet species-specific levels and homemade plans should be carefully supplemented.
02
L-Carnitine
L‑Carnitine is a nutrient-like compound added to pet foods and supplements to support fat metabolism by transporting long-chain fatty acids into mitochondria, helping promote lean muscle maintenance, weight management, and cardiac energy metabolism in dogs and cats. It can be beneficial for overweight, geriatric, athletic, or cardiac patients and is generally safe at recommended levels, but therapeutic dosing should be guided by a veterinarian since healthy animals can synthesize some carnitine and excess supplementation may cause gastrointestinal upset.
03
CoQ10
CoQ10 (coenzyme Q10) is an antioxidant and mitochondrial cofactor often added to pet foods or supplements to support cellular energy production and promote cardiovascular health. It can benefit aging or cardiac-compromised dogs and cats by helping reduce oxidative stress and support metabolism, but dosing and effectiveness vary, so consult your veterinarian—especially if your pet is on medications or has a serious health condition.
04
Hawthorn Berry
Hawthorn berry is used in pet foods and supplements as a botanical ingredient for flavor and a source of antioxidants and soluble fiber, and is sometimes included in formulations aimed at supporting cardiovascular health—most commonly for dogs and less often for cats. It offers modest antioxidant and digestive benefits but contributes little macronutritional value; because it can interact with prescription cardiac medications or cause sensitivities in some animals, pet owners should consult their veterinarian before use.
05
Vitamin E
Vitamin E is a fat‑soluble vitamin and antioxidant commonly added to dog and cat foods both as an essential nutrient and to protect fats and fat‑soluble vitamins from oxidation. It supports immune function, healthy skin and coat, and cellular protection; deficiency is uncommon in complete diets, while excessive supplemental doses are unnecessary and very high amounts may interfere with blood clotting or interact with certain medications.
