The science behind WITHIN
Our bespoke blend of scientifically proven prebiotics, postbiotics, antioxidants, vitamins & minerals - designed to optimise digestive wellbeing and immunity for whole-body health from the inside out.
Numbers that mean something
These results come from a 60-day randomised controlled study of 348 dogs. Half received our postbiotic blend daily. Half received a placebo. The difference showed up in the data and in the bowl.
FormulaBiotics™ supports digestive health from the inside out, helping to maintain a healthy gut microbiome, support immune function and promote overall wellbeing. The result? Benefits your dog can feel and you may notice every day.
The process
We recreate the natural fermentation process already happening within your
dog's gut — then deliver it consistently in every meal.
Saccharomyces cerevisiae
yeast-based probiotic
undergoes a unique
fermentation process
Made into a precise
combination of hundreds of
postbiotic metabolites
Added to every Within recipe —
stable and effective in any
processing condition
Hundreds of postbiotic
metabolites delivered
consistently and directly to your
dog's gut
Every ingredient earns its place. Here's what we put in and why it matters for your dog.
Freshly Prepared Salmon
Rich in Omega-3 and Omega-6 fatty acids for a glossy coat, healthy skin, and cognitive function. A brilliant protein source for dogs with sensitivities to more common meats.
Chicory Root (FOS)
A natural prebiotic fibre that selectively feeds beneficial gut bacteria. Supports a balanced microbiome, promotes healthy stool consistency, and maintains digestive regularity day to day.
Dried seaweed
Natural Norwegian kelp with a dual role: prebiotic fibre supporting a healthy oral and gut microbiome, and at 100mg per dental chew, clinically evidenced to reduce plaque and tartar accumulation.
Inactivated yeast
The cornerstone of FormulaBiotics™. Unlike live probiotics, inactivated yeast cell wall components modulate immune response and gut integrity without needing to survive digestion. Consistent across every product, every batch.
Blueberry, Rosemary & Spinach
A trio of natural antioxidants working together to combat oxidative stress. Blueberry supports cognitive function and immune resilience, rosemary contributes natural preservation and anti-inflammatory properties, and spinach delivers iron, vitamins and additional antioxidant support, small quantities, meaningful impact.
Omega 3 & 6 (Salmon Oil)
The natural source of essential fatty acids that keep skin healthy and coat glossy. Salmon oil delivers Omega 3 and 6 in their most bioavailable form, working from the inside out for visible results you'll notice within weeks.
