Allergy & Immune Soft Chews Supplement

Mushrooms are used in pet foods as a low‑calorie vegetable ingredient and flavor enhancer that adds dietary fiber and bioactive components such as beta‑glucans, antioxidants, B vitamins, and minerals. These compounds can modestly support immune health and antioxidant status in dogs and cats, but mushrooms should be included only in moderation and sourced/processed safely because some wild species are toxic and some pets may experience allergies or gastrointestinal upset.

Reishi (Ganoderma lucidum) is a medicinal mushroom used in pet foods and supplements as a functional ingredient for immune support and antioxidant benefits rather than as a primary nutrient. It contains polysaccharides and triterpenes that may help modulate immunity and inflammation, but evidence in dogs and cats is limited, product quality and dosing vary, and it can interact with immunosuppressive or anticoagulant medications or cause gastrointestinal upset, so consult your veterinarian before use.

Turkey Tail mushroom is used in pet foods and supplements as a functional, medicinal ingredient providing bioactive polysaccharides (notably beta‑glucans and PSK/PSP) and prebiotic fibers to support immune function and gut microbiome health rather than serving as a primary protein or vitamin source. It may offer antioxidant and immune‑modulating benefits for dogs and cats, but should be food‑grade and quality‑tested, used at appropriate doses, and discussed with a veterinarian—especially for pets on immunosuppressive drugs or chemotherapy—since interactions and gastrointestinal upset can occur at higher intakes.

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.

Quercetin dihydrate is a plant-derived flavonoid antioxidant commonly added to pet supplements and some functional foods for its anti-inflammatory and mast-cell stabilizing properties rather than as a traditional nutrient; in dogs and cats it is often used to help manage allergic reactions, support immune health, and reduce oxidative stress. While generally well tolerated and potentially helpful for seasonal allergies and inflammatory conditions, efficacy data in pets are limited, and it should be used under veterinary guidance because dosing, possible gastrointestinal upset, and interactions with certain medications (e.g., anticoagulants or drugs metabolized by liver enzymes) need to be considered.
