Top Pick
This product functions as a supplement-style topper rather than a complete diet, so it should only be used alongside a balanced dog food. It’s a concentrated mix of protein, fiber, and botanicals, including cordyceps, reishi, echinacea, and quercetin. It may appeal to owners wanting to add a mushroom- and herb-based blend to support their dog’s overall diet.

Benefits the manufacturer highlights in its own product marketing. KibbleLab lists them for reference and does not verify these claims.KibbleLab Review
Strengths
- Very high protein for a topper, mainly from nutritional yeast and chicken bone broth.
- Includes cordyceps and reishi mushrooms, which are being studied for potential immune-modulating effects.
- Contains quercetin and various herbs and botanicals that some owners seek for allergy or immune support.
- Low moisture powder format makes it easy to sprinkle over most types of dog food.
Considerations
- This is not a complete and balanced food, so it must be fed with a nutritionally complete dog diet.
- Chicken bone broth may be an issue for dogs with chicken allergies or strict elimination diets.
- Nutritional yeast can occasionally bother dogs with yeast sensitivities or very sensitive stomachs.
- Herbal and mushroom blends can be too stimulating for some dogs; introduce slowly and monitor for any changes.

Top 5 Ingredients Explained
01
Nutritional Yeast
Nutritional yeast is a deactivated yeast (usually Saccharomyces cerevisiae) used in pet foods and as a supplemental flavoring to add a savory taste along with B‑complex vitamins, some protein and fiber; fortified products may also supply vitamin B12 while unfortified forms do not reliably provide it. It can support skin, coat and general nutrient intake—especially in homemade or limited diets—but animals with yeast sensitivities, certain metabolic or urinary stone conditions, or those already receiving balanced supplements should use it cautiously and under veterinary guidance to avoid dietary imbalance or upset.
02
Chicken Bone Broth
Chicken bone broth is commonly used as a palatability enhancer and hydration topper in dog and cat diets, supplying gelatin, collagen-derived amino acids and trace minerals that may support joint comfort and gut health while making food more appealing. It is not a complete food, so choose low-sodium, additive-free products (avoid broths containing onion, garlic or excessive fat), and ensure no bone fragments are present—use caution with pets that have pancreatitis, sodium-sensitive conditions, or known food sensitivities.
03
Burdock
Burdock root is used as a botanical additive and source of dietary fiber and prebiotic inulin in some dog and cat foods and supplements, where it may help support gut health and provide antioxidant compounds. Evidence for specific benefits in pets is limited, and it can cause gastrointestinal upset in sensitive animals or interact with diuretics and hypoglycemic medications, so products containing burdock should be used with veterinary guidance.

04
Echinacea Purpurea
Echinacea purpurea is an herbal botanical sometimes included in pet supplements or functional foods for its purported immune-supporting and antioxidant properties rather than as a source of macronutrients. Evidence of benefit in dogs and cats is limited, and it can cause gastrointestinal upset or allergic reactions and may interact with immunosuppressive medications, so use should be guided by a veterinarian, especially for pets with autoimmune conditions or on concurrent drugs.
05
Fennel Seed
Fennel seed is typically added to pet foods and treats as a flavoring and mild digestive aid, contributing small amounts of fiber, antioxidants, and aromatic essential oils that can help reduce gas and support gastrointestinal comfort in some dogs and cats. While generally safe in small amounts, its concentrated essential oils and phytoestrogens mean large quantities can cause stomach upset or hormonal concerns, so it should be used sparingly and avoided or discussed with a veterinarian for pregnant, nursing, or hormonally sensitive pets.
