WHY DIGESTIVE NUTRITION MATTERS

A Healthy Gut Is Part Of A Healthy Routine


Your dog's digestive system is constantly interacting with their food, their environment and the microorganisms that naturally live within the gut.

That's why we believe digestive support shouldn't be about throwing one ingredient into a tub and calling it a formula. PreproFlex Advanced is built around several complementary nutritional approaches.

01

Prebiotic Support

Multiple prebiotic components provide nutritional support for beneficial bacteria already present within the digestive system.

02

Probiotic Support

A selected Bacillus strain provides over 1 billion CFU per 7g serving to complement the nutritional formula.

03

Postbiotic Support

Yeast fermentate provides postbiotic components that complement the prebiotic and probiotic elements of the formula.

THE PREPROFLEX APPROACH

More Than Just A Probiotic


A probiotic is only one part of the picture. PreproFlex Advanced combines several nutritional components designed to work alongside one another as part of your dog's everyday digestive routine.

PREBIOTICS

Feed The Beneficial Microbiome

PreproFlex contains mannan-rich fraction, fructo-oligosaccharides and beta-1,3/1,6-glucans as part of its prebiotic approach.

PROBIOTIC

Over 1 Billion CFU Per Serving

The Bacillus subtilis C-3102 / Bacillus velezensis DSM 15544 component provides approximately 1.022 billion CFU in a 7g serving, based on the declared 1.46 × 1011 CFU per kg.

POSTBIOTIC

Yeast Fermentate

A fermentation-derived component included to complement the prebiotic and probiotic elements of the formula.

More Than Just A Probiotic


Your dog's digestive system is home to a complex community of microorganisms. PreproFlex Advanced is designed to support that environment from more than one direction, combining prebiotic ingredients, a carefully selected probiotic strain, postbiotic components and fibre in one complete daily formula.

01 · Prebiotics

Feed The Beneficial Microbiome

PreproFlex contains several complementary prebiotic components, including mannan-rich fractions, fructo-oligosaccharides (FOS) and beta-glucans. These provide nutritional support for beneficial microorganisms already present within the digestive tract.

02 · Probiotic

Over 1 Billion CFU Per 7g

The formula contains Bacillus subtilis C-3102 / Bacillus velezensis DSM 15544, a selected probiotic strain. At the 7g feeding level, the labelled inclusion provides approximately 1.022 billion CFU.

03 · Postbiotics

Fermentation-Derived Support

Yeast fermentate from Saccharomyces cerevisiae provides postbiotic components that complement the prebiotic and probiotic elements of the formula, helping create a more comprehensive approach to everyday digestive nutrition.

A Layered Approach

Four Complementary Elements. One Daily Formula.

PRE

Prebiotic Nutrition

MRF, FOS and beta-glucans to nourish beneficial microorganisms.

PRO

Probiotic Support

A selected Bacillus strain delivering over 1 billion CFU at 7g.

POST

Postbiotic Components

Yeast fermentate to complement the wider digestive support formula.

FIBRE

Pumpkin Fibre

Pumpkin provides a naturally occurring source of fibre within the formula.

What's Inside PreproFlex Advanced?


Every component has a purpose. Rather than relying on a single headline ingredient, PreproFlex Advanced brings together different nutritional approaches to create a thoughtfully balanced digestive formula.

Probiotic

Bacillus DSM 15544

A carefully selected Bacillus strain included at a substantial labelled inclusion level. The formula provides approximately 1.022 billion CFU per 7g, calculated from the declared 1.46 × 1011 CFU per kg.

Prebiotic

Mannan-Rich Fraction

A specialised yeast-derived prebiotic fraction that forms part of the formula's microbiome-supporting approach, providing nutritional support for beneficial microorganisms within the digestive environment.

Prebiotic

Fructo-Oligosaccharides

FOS are prebiotic fibres included to provide nutritional support for beneficial bacteria already present within the digestive system.

Prebiotic

Beta-Glucans

Beta-1,3/1,6-glucans from yeast form another part of the prebiotic component, complementing the MRF and FOS within the wider formula.

Postbiotic

Yeast Fermentate

Derived from Saccharomyces cerevisiae, yeast fermentate provides postbiotic components that work alongside the prebiotic and probiotic elements of the formula.

Natural Fibre

Pumpkin

Pumpkin provides naturally occurring fibre and is a familiar ingredient in thoughtfully formulated digestive nutrition for dogs.

Functional Ingredient

Clinoptilolite

A naturally occurring mineral included as an anticaking agent within the formula, helping maintain the physical quality and consistency of the powder.

Functional Ingredient

Bentonite

A naturally occurring clay mineral with a recognised role in animal nutrition. Included as a binder, it forms part of the formula's broader digestive support approach.

The result? A genuinely multi-layered digestive formula that doesn't stop at adding a probiotic. PreproFlex Advanced combines prebiotic nutrition, a high-inclusion probiotic strain, postbiotic components and pumpkin fibre to support your dog's everyday digestive wellbeing.
