Postbiotics Plus Supplement
Verified Jun 20, 2026
This is a powdered prebiotic and postbiotic supplement for dogs and cats designed to support gut and immune health alongside their regular diet. It features branded postbiotic and prebiotic ingredients plus an organic herbal blend including fennel, licorice root, slippery elm, thyme, and ginger to help maintain normal digestive function. It can be used for most dogs and cats of any age or size that may benefit from extra digestive support.
A thoughtfully formulated digestive supplement that combines postbiotics, prebiotics, and soothing organic herbs to support the intestinal tract and immune system in both dogs and cats. It’s best suited as an add-on to a complete and balanced diet for pets with mild digestive ups and downs or those who need ongoing gut support. As with any supplement, it’s important to introduce it slowly and monitor your pet’s response, especially if they have existing medical conditions or take other medications.

KibbleLab Review
Strengths
- Includes both postbiotics (Tynagen) and prebiotics (Actigen), which can work together to support a healthy gut microbiome and normal stool quality.
- Herbal blend with slippery elm, licorice root (DGL), fennel, ginger, and thyme may gently soothe the GI tract and support normal digestion.
- Powder format makes it easy to mix into food for both dogs and cats across all sizes and life stages.
- Free of common food proteins like chicken or beef, which can be helpful for pets that are already on a restricted or novel-protein diet.
Considerations
- This is a supplement, not a complete diet, so it should only be used alongside a balanced dog or cat food, not as a primary source of nutrition.
- Herbal ingredients such as licorice root and ginseng extracts can interact with certain health conditions or medications, so it’s wise to check with your veterinarian before starting, especially for pets with chronic disease.
- Some very sensitive pets may experience soft stools or gas when prebiotic/postbiotic products are introduced too quickly; starting with a smaller amount and gradually increasing can help.

Top 5 Ingredients Explained
01
Tynagen
I could not find verifiable information on an ingredient called "Tynagen" in standard pet nutrition references; it may be a proprietary or trade name, so please provide the manufacturer or product context. With that detail I can summarize its typical role in pet food, nutritional relevance for dogs and/or cats, and any important benefits or precautions.
02
Actigen
Actigen is a proprietary, yeast‑derived ingredient (a mannose/mannan‑rich fraction) used in pet foods as a functional prebiotic and immune‑support additive to help maintain intestinal health and promote beneficial gut microflora. It is not a primary nutrient but may support digestive resilience and the pet’s natural defenses when included at appropriate levels; pets with known yeast sensitivities should be monitored and benefits depend on overall diet and inclusion rate.
03
AstraGen
AstraGen is a proprietary botanical extract used in supplements and some pet foods as a bioavailability enhancer to support nutrient absorption and digestive health. It is promoted to help improve uptake of amino acids, vitamins and minerals—which may be helpful for older or digestive‑compromised dogs and cats—but pet‑specific safety and efficacy data are limited, so use should follow manufacturer dosing and a veterinarian’s guidance.
04
Astragalus
Astragalus is an herbal botanical used in pet foods and supplements as an immune-supporting ingredient and antioxidant rather than a macronutrient; its root contains polysaccharides and flavonoids that are thought to have adaptogenic and immune-modulating effects for dogs and cats. Evidence in companion animals is limited, so benefits are modest and product quality varies; caretakers should be aware of possible gastrointestinal upset, allergic reactions, and interactions with immunosuppressive or anticoagulant medications and consult their veterinarian before use.
05
Ginseng
Ginseng is an herbal supplement sometimes added to pet foods or treats as an adaptogen and antioxidant intended to support energy, immune function and general vitality, though it is not an essential nutrient or a primary protein/fiber source. Evidence of benefit in dogs and cats is limited, and ginseng can cause gastrointestinal upset, affect blood sugar, interact with medications (such as anticoagulants or diabetes drugs), or overstimulate sensitive animals, so use should be guided by a veterinarian and avoided in pregnant, nursing, or seizure-prone pets.
