Vital Digest Digestive Enzyme Powder Supplement
Verified Jun 11, 2026
This is a digestive enzyme powder supplement for dogs and cats designed to be mixed with their regular food. It uses plant-derived enzymes from Aspergillus species and pineapple stem (bromelain), with maltodextrins and lactose as carriers, to help break down fats, carbohydrates, proteins, and fiber in the diet. It can be useful for pets who may benefit from extra digestive support on top of a complete and balanced food.
A thoughtfully formulated digestive enzyme supplement using multiple plant-based enzymes to support the digestion of fats, carbs, proteins, and fiber in both dogs and cats. The specific enzyme activity guarantees are a nice sign of quality control and consistency. It’s best used as an adjunct to a complete, balanced diet rather than as a substitute for addressing underlying medical digestive problems with your veterinarian.

At a Glance
KibbleLab Review
Strengths
- Provides a broad spectrum of enzymes (amylase, lipase, bromelain/protease, and cellulase), which can help break down all major nutrient groups in food.
- Enzyme activity levels are clearly listed, suggesting attention to potency and quality control.
- Powder format makes it easy to mix into either dry or wet food for dogs and cats of all sizes.
- Plant-derived enzymes are generally well tolerated and work across a wide pH range in the stomach and intestines.
Considerations
- Contains lactose, which may not be ideal for pets with known lactose sensitivity or dairy allergies.
- Also uses maltodextrins as a carrier; while common and generally safe, they do not add nutritional value and may not suit owners seeking very minimal-ingredient supplements.
- This is a supplement, not a complete diet, so it should only be used alongside a balanced dog or cat food rather than as a primary source of nutrition.
- If a pet has ongoing vomiting, diarrhea, weight loss, or other digestive problems, this should not replace a proper veterinary workup to look for underlying disease.

Top 5 Ingredients Explained
01
Maltodextrin
Maltodextrin is a processed, rapidly digestible carbohydrate commonly used in pet foods and treats as a binder, bulking agent, texture improver and flavor carrier. It supplies easily metabolized calories but offers little in the way of vitamins, minerals or fiber, so excessive inclusion can contribute to weight gain or blood sugar spikes in obese or diabetic dogs and cats, and it may cause digestive upset in sensitive pets; sources can include corn, wheat, potato or rice, so check for potential allergen concerns.
02
Lactose
Lactose is the primary sugar from milk commonly present in pet foods and treats as a carbohydrate source, palatability enhancer and component of milk powders or whey-based ingredients. Young animals digest lactose better than adults, but many adult dogs and cats have low lactase activity and can develop gas, diarrhea or other GI upset, so lactose-containing products should be used cautiously—particularly in lactose-intolerant or diabetic pets—and milk-derived ingredients may also introduce trace milk proteins that can trigger allergies.
03
Aspergillus Oryzae
Aspergillus oryzae is a filamentous fungus used in pet food primarily as a fermentation organism and source of digestive enzymes (such as amylases, proteases and lipases) to pre-digest carbohydrates and proteins, improving nutrient availability and overall digestibility for dogs and cats. When produced as a controlled, food‑grade ingredient it can enhance palatability and reduce anti-nutritional factors, but manufacturers should use validated GRAS strains and good manufacturing practices to avoid contaminants, and pets with specific sensitivities or severe immunocompromise should be monitored when fed fungal-derived products.
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
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.
