Where these benefits come from
Benefits the manufacturer highlights in its own product marketing. KibbleLab lists them for reference and does not verify these claims.KibbleLab Review
Strengths
- Includes a 6-strain probiotic blend, which can help support a healthy gut microbiome in many dogs.
- Uses turmeric, chaga, reishi, bromelain, and quercetin, all commonly used for their anti-inflammatory and antioxidant properties.
- Contains mixed tocopherols as a natural preservative, which helps keep the fats in the product stable.
- Soft chew format is generally easy for most adult and senior dogs to eat and can be used like a treat.
Considerations
- This is a supplement, so it must be fed together with a complete and balanced dog food, not as the main diet.
- Dogs with oat or coconut sensitivities should avoid this product, as both are included in the base.
- Herbal and mushroom ingredients can affect dogs differently, so introduce slowly and watch for any digestive upset.

Top 5 Ingredients Explained
01
Turmeric
Turmeric is a spice used in pet foods and supplements primarily for its antioxidant and anti-inflammatory compound curcumin, and is included as a flavor/colorant or complementary joint and digestive support ingredient rather than a primary nutrient. It can offer potential benefits—particularly for dogs—when properly formulated with a bioavailability enhancer (e.g., black pepper or fat), but large amounts may cause gastrointestinal upset, cats can be more sensitive to concentrated spices, and turmeric/curcumin may interact with blood thinners or diabetes medications, so veterinary guidance is recommended before use.

02
Apple Cider Vinegar
Apple cider vinegar is typically used in pet foods or supplements as a flavoring, acidity regulator and mild preservative rather than a significant source of nutrients, and it is sometimes added in small amounts to treats or diet toppers for palatability or anecdotal digestive support for dogs and cats. Raw, unfiltered varieties contain the “mother” which some claim has beneficial microbes, but evidence is limited, and concentrated vinegar can irritate the mouth, throat or stomach and may be contraindicated for animals with GI, kidney, or metabolic conditions—consult your veterinarian before use.
03
Chaga
Chaga is a medicinal mushroom added to pet foods and supplements as a functional ingredient for its antioxidant compounds and immunomodulatory polysaccharides (e.g., beta‑glucans), rather than as a protein or caloric ingredient, and is promoted for potential immune‑support and anti‑inflammatory effects in dogs and cats. Because robust clinical data in pets are limited, chaga should be used cautiously—source quality can vary, it may interact with immunosuppressive or anticoagulant medications, and it is generally avoided in pregnant or nursing animals and those with bleeding disorders.
04
Reishi Mushroom
Reishi mushroom is used in pet foods and supplements as a functional ingredient rich in polysaccharides (notably beta-glucans) and antioxidants, primarily to support immune function and provide anti-inflammatory and adaptogenic effects rather than as a protein or vitamin source. While some studies and anecdotal reports suggest benefits for dogs and cats, evidence in pets is limited and quality/strength of extracts varies, so owners should consult their veterinarian—especially if their animal is on immunosuppressive drugs, has an autoimmune condition, or shows signs of allergy or digestive upset.
05
Bromelain
Bromelain is a proteolytic enzyme derived from pineapple that is used in pet foods and supplements as a digestive aid and anti-inflammatory adjunct to help break down proteins and potentially support gastrointestinal comfort and joint-related inflammation in dogs (it is less commonly used in cats). Because bromelain is heat-sensitive and typically added as a supplement rather than an essential nutrient, its effectiveness can vary; it may cause gastrointestinal upset or allergic reactions and can increase bleeding risk or interact with certain medications, so consult your veterinarian before use.
