DESCRIPTION

If your dog struggles with sensitive digestion, inconsistent stools, or the occasional upset tummy, a healthier gut can make everything easier — for both of you.

BioFunction 8 is a natural, vet-approved blend created to support your dog’s digestive balance and everyday gut health.

This gentle formula combines organic chia seeds, calming chamomile, soothing marshmallow root, and a unique trio of nutrient-rich seaweeds. Together, they work to:

Support healthy, regular digestion
Soothe and calm the gut
Encourage consistent, well-formed stools
Promote overall digestive comfort

The result? Fewer stomach-related hiccups, easier mealtimes, and more comfortable, stress-free walks.

It’s completely natural, sustainably sourced, and safe for daily, long-term use.

And using it couldn’t be simpler — just sprinkle the recommended amount over your dog’s food once a day and let the nutrients do the work.

Give your dog the gentle digestive support they need to feel their best — every single day.

INGREDIENTS

Organic Chia Seeds (Salvia hispanica)

A natural source of soluble fibre and plant-based omega fatty acids. Gently supports normal digestive regularity and healthy stool formation.

Organic Chamomile Flowers (Matricaria chamomilla)

Traditionally used for their calming properties. Provides gentle botanical support for a comfortable, settled gut.

Organic Marshmallow Root Powder (Althaea officinalis)

A soothing herb valued for its naturally mucilaginous compounds that help support the integrity of the digestive tract.

Seaweed Blend (Fucaceae, Ulvaceae, Ulvophyceae)

A balanced combination of brown and green seaweeds providing natural minerals, polysaccharides, and marine phytonutrients. Sustainably harvested and free from additives or fillers.

USAGE

Sprinkle the recommended amount over your dog’s food once daily.

Start with just a pinch and increase to their recommended dosage gradually over several days. Use consistently as part of their regular feeding routine.

Biofunction 8 is safe to use alongside other supplements when fed as directed. When feeding marine-based ingredients, keep total intake to no more than 5% of your dog’s overall diet to help maintain a balanced intake of naturally occurring iodine.
