The science behind a settled, healthy gut

Verified digestibility, not just quality ingredients

Recipe: Duck & Herring

For dogs with sensitive stomachs, the form protein arrives in matters as much as the source. Independent laboratory data proves what this recipe actually delivers.

Verified digestibility, not just quality ingredients

Eden Gourmet Duck & Herring is a complete, grain-free dry food formulated around freshly prepared duck and herring. Independent testing at the University of Bradford and ALS Laboratories UK confirms exactly how this recipe supports digestive health, from the protein form to the fatty acid balance.

82%
of protein peptides are under 2kDa (82% of the protein is presented in forms that place minimal load on the digestive system)
328 mg
EPA & DHA per 100g: marine omega-3s that support the gut lining and reduce inflammation

Protein that works with the gut, not against it

Why this matters for sensitive stomachs

Large intact proteins are a primary source of digestive effort, and a major trigger for sensitive gut reactions. Hydrolysis during cooking pre-digests the protein before it ever reaches your dog's gut.

63% of all protein in this recipe arrives as di- and tri-peptides, absorbed directly through the gut wall via dedicated transporters. Over 82% sits below the 2 kDa threshold associated with reduced allergen risk.

As a reference point, Royal Canin's hydrolysed veterinary diets describe peptides under 10 kDa as hypoallergenic. The Bradford analysis shows the overwhelming majority of peptides in Duck & Herring are well below that level.

The building blocks your gut lining needs every day

The cells lining the gut turn over completely every few days. This recipe supplies the specific amino acids that fuel that renewal, measured on the finished kibble.

Amino acid Role in gut health g / 100g
Glutamic acid Primary fuel for enterocytes (gut lining cells) 3.05
Aspartic acid Nucleotide & energy metabolism in gut lining 2.41
Arginine Intestinal blood flow & immune function 1.74
Glycine Mucin synthesis & intestinal barrier 1.81
Threonine Mucin turnover & gut lining structure 1.05
Lysine Protein utilisation & tissue repair 1.65
Proline Enterocyte structure & repair 1.28
Methionine Antioxidant glutathione precursor 0.49
