Synbiotic Gut Health Powder

Synbiotic Gut Health Powder

Overview

5 Hounds Synbiotic Powder is a gut health supplement formulated for dogs of all life stages, combining probiotics, prebiotics, and postbiotics in a single daily powder. The probiotic strain is Bacillus subtilis, which supports digestion and immune defence. Prebiotics — including chicory root inulin, organic pea fibre, green banana, and resistant starch — provide fermentable substrate for beneficial gut bacteria. Postbiotics from inanimate Bacillus subtilis supply bioactive compounds associated with gut integrity and systemic health. The powder is shelf-stable for 12 months without refrigeration and dosed at one scoop per 12kg of body weight daily. The brand recommends it particularly during dietary transitions, where digestive disruption is common, as well as for ongoing gut maintenance. It is a supplement, not a complete food, and is intended for use alongside a balanced primary diet.

Summary

Bacillus subtilis is a beneficial bacterium of microbial origin commonly included in pet foods as a probiotic. Its primary purpose is to support digestive health by promoting a balanced gut microbiome and enhancing nutrient absorption. Bacillus subtilis is not used in its wild, environmental form; instead, it is cultivated and processed under controlled conditions to ensure safety, stability, and efficacy in pet nutrition.

Manufacturer Benefits

Bacillus subtilis is included as a probiotic to support digestive health and optimise gut flora balance in pets. Its addition can also serve as a marketing differentiator, appealing to consumers seeking functional and health-promoting ingredients.

Summary

Inactivated Bacillus subtilis refers to a preparation of the Bacillus subtilis bacterium that has been rendered non-viable, typically through heat or chemical treatment. In dog food manufacturing, it is supplied as a dried, inactivated bacterial culture. This ingredient is used as a probiotic adjunct to support gut health and maintain a balanced intestinal microflora in dogs. When included at appropriate levels, inactivated Bacillus subtilis is considered safe, with no known adverse effects reported in canine diets.

Manufacturer Benefits

Inactivated Bacillus subtilis is included in dog food formulations primarily to support digestive health and immune function in dogs, while also offering manufacturers a stable, shelf‑friendly probiotic option that withstands processing and storage conditions. Its use benefits both the animal and the manufacturer by providing functional value without compromising product stability.

Summary

Chicory root inulin is a plant-derived soluble fibre extracted from the root of the chicory plant (Cichorium intybus). It is primarily included in pet food to support digestive health by promoting beneficial gut bacteria and improving stool quality. Rather than using the whole root, inulin is utilised in its purified form to optimise its prebiotic benefits and ensure consistent, safe inclusion in formulations.

Manufacturer Benefits

Chicory root inulin is included as a prebiotic fibre to support digestive health and promote beneficial gut bacteria in pets. It also serves as a label-friendly ingredient that appeals to health-conscious consumers seeking functional benefits in pet food.

Its inclusion helps regulate bowel movements and can contribute to a feeling of fullness in pets.

Manufacturer Benefits

Pea fibre is included as a cost-effective, label-friendly source of dietary fibre to aid digestive health and improve stool quality. It also serves as a bulk-adding agent, helping to optimise product texture and maintain formulation consistency.
