If you’ve looked closely at our Gut & Immune chews, you’ll have seen EpiCor® listed as a hero ingredient. It’s one of the things that sets PawStrong apart, so here’s what it actually is, in plain English.
The short answer
EpiCor® is a postbiotic. A natural, dried ingredient made from a special yeast (Saccharomyces cerevisiae) that’s been fermented and then deactivated. That fermentation process creates a rich mix of beneficial compounds, including beta-glucans, polyphenols and other metabolites, which support the gut and the immune system when your dog eats them.
It’s made to a consistent, branded standard and is recognised as one of the world’s leading postbiotic ingredients, used in both human and pet wellness products.
What’s a postbiotic, again?
It’s the newest of the three “biotics”, and the easiest to misunderstand. Here’s the simple version:
• Probiotics are live good bacteria.
• Prebiotics are the fibres that feed them.
• Postbiotics are the beneficial compounds produced through fermentation (the outcome of all that bacterial activity), delivered to your dog directly.
The advantage of a postbiotic like EpiCor® is that it doesn’t rely on live organisms surviving storage and digestion to do their job. The beneficial compounds are already there, ready to go. Read our full guide to prebiotics, probiotics and postbiotics →
What it does for your dog
A large share of a dog’s immune system is located in and around the gut, which is why gut health and immune health are so closely linked. EpiCor® works on both:
• Supports a healthy gut environment and digestion
• Helps support the dog’s natural immune defences
• Delivers beneficial metabolites directly, without needing to colonise the gut first
It’s a particularly good fit for dogs with sensitive tummies, and for breeds that are more prone to digestive issues.
Why we chose it
PawStrong is built on a simple principle: use premium, science-backed ingredients at levels that actually do something — and tell you exactly what’s in there and why. EpiCor® fits that perfectly. Rather than a vague “supports gut health” blend, it’s a named, branded, well-studied postbiotic that we’re happy to put front and centre.
You’ll find EpiCor® in our Gut & Immune chews.
