Complete Gut Health Complex Probiotics & Digestive Enzymes Powder Supplement
Verified Jun 15, 2026
A digestive support powder designed for both dogs and cats, this supplement combines multiple probiotic strains, prebiotic fiber, and digestive enzymes. It’s intended to be sprinkled onto regular food to help support gut bacteria balance and the breakdown of proteins, fats, and carbohydrates. This can be useful for pets who need a little extra gastrointestinal support alongside a complete diet.
This is a well-formulated digestive supplement that provides a blend of probiotic strains, prebiotic inulin, and digestive enzymes for dogs and cats. The ingredient list is straightforward and focused on gut support without unnecessary additives. It’s a reasonable option for pets who may benefit from added probiotics and enzymes on top of their regular complete and balanced food.

At a Glance
KibbleLab Review
Strengths
- Contains multiple probiotic strains (Lactobacillus and Bifidobacterium species), which can help support a healthy gut microbiome.
- Includes prebiotic inulin from chicory root to help feed beneficial gut bacteria.
- Provides several digestive enzymes (protease, amylase, lipase, cellulase) to aid in breaking down proteins, fats, carbohydrates, and fiber in the diet.
- Powder format with species-specific scoop guidelines makes it easy to adjust dosing for both dogs and cats of different sizes.
Considerations
- This is a supplement, not a complete and balanced diet, so it must be used alongside a regular dog or cat food.
- Pets with true food allergies or sensitivities should have any new supplement introduced gradually and monitored for changes in stool or skin.
- Digestive enzyme and probiotic supplements are not universally necessary; healthy pets on a balanced diet may not see a noticeable benefit.

Top 5 Ingredients Explained
01
Aspergillus Niger Fermentation Product
Aspergillus niger fermentation product is a fermentation-derived ingredient used in pet foods primarily as a source of enzymes and fermentation flavors to enhance palatability and aid digestion. When produced to food-grade standards it can help break down complex carbohydrates and phytates to improve nutrient availability and reduce phosphorus excretion, but it is not a primary nutrient and animals with known sensitivities to fungal-derived ingredients should be monitored.
02
Inulin
Inulin is a soluble prebiotic fiber commonly added to pet foods to promote beneficial gut bacteria, improve stool quality, and provide low‑calorie bulk for weight management. It can support digestive health and mineral absorption in dogs and cats but may cause gas, bloating or loose stool if used in excess or introduced too quickly, so amounts should be moderated for sensitive animals.
03
Flaxseed
Flaxseed is used in pet foods as a plant-based source of alpha‑linolenic acid (ALA) omega‑3, soluble and insoluble fiber, and modest protein, often added to support skin and coat condition, digestive health, and kibble texture; ground seed or flaxseed oil is more digestible than whole seed. Dogs can partially convert ALA to long‑chain EPA/DHA but cats convert ALA poorly and therefore still need marine sources for essential DHA/EPA; flax is calorie‑dense, prone to oxidation if not stabilized, and contains lignans (phytoestrogens) and trace cyanogenic compounds, so it should be processed and used in moderation.
04
Aspergillus Oryzae Fermentation Product
Aspergillus oryzae fermentation product is a fermentation-derived ingredient commonly added to pet foods to supply microbial enzymes and fermentation metabolites that aid digestion, enhance palatability, and improve nutrient availability. In dogs and cats it can help break down starches and proteins and support stool quality, but product quality and manufacturing controls are important to avoid contaminants, and pets with severe immune suppression or known mold sensitivities should be discussed with a veterinarian.
05
Bifidobacterium Longum Fermentation Product
Bifidobacterium longum fermentation product is a probiotic-derived ingredient used in pet foods and supplements to deliver B. longum cultures or their fermentation metabolites (postbiotics) that help support a balanced gut microbiome. It may aid digestion, stool quality and immune health in dogs and cats, but benefits are strain- and formulation-dependent and caregivers should follow storage directions and consult a veterinarian before use in very young, elderly or immunocompromised pets.
