What Is EpiCor® for Dogs? The Postbiotic Explained | PawStrong

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.

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.
