6 ingredients in this list are ones we hold sourced evidence on , and none of them is contested in the veterinary literature.

• Named Meat/Poultry Meal (e.g., Chicken Meal, Lamb Meal) · ingredient 4Well supportedA rendered, water- and fat-reduced concentrate from a named species (AAFCO, e.g., 'chicken meal'). Because most moisture is removed it is a dense protein source (poultry meals commonly around 57-69% crude protein) and it names the species for allergy avoidance.
• Mixed tocopherols (natural vitamin E) · ingredient 8Well supportedA blend of vitamin E forms (alpha-, beta-, gamma-, delta-tocopherol) used as a natural-source antioxidant to slow fat rancidity, commonly chosen as an alternative to synthetic preservatives. EFSA concluded that tocopherol-rich extracts are safe for all animal species and the consumer and are efficacious antioxidants in feed.
• Corn Gluten Meal · ingredient 3NeutralThe dried protein fraction of corn, used as a concentrated plant protein (roughly 60% protein) rather than a filler. Its amino acids are highly digestible in dogs (reported up to about 95%), though lysine is the first-limiting amino acid, so complete diets balance it with other protein sources.
• Prebiotics (chicory root / inulin, FOS) · ingredient 14NeutralFermentable fibers (chicory-derived inulin and fructooligosaccharides) that feed colonic bacteria and are readily fermented to short-chain fatty acids in dogs. Feeding studies show they shift fecal microbiota composition and are well tolerated at typical inclusion levels, but clear health benefits beyond compositional change are not yet established.
• Taurine (supplemental) · ingredient 23NeutralA sulfur amino acid that dogs can normally synthesize from methionine and cysteine, so it is not classically essential for them. However, some breeds (e.g., golden retrievers) and some diets are linked to low taurine status and dilated cardiomyopathy: an observational study (Ontiveros 2020) associated non-traditional, largely grain-free diets with taurine deficiency and DCM-consistent echocardiographic changes in golden retrievers, though causation and mechanism remain under investigation.
• Probiotics (live microbials) · ingredient 24NeutralLive microbial supplements (e.g., Enterococcus faecium SF68, dried fermentation products) intended to support gut health. A 2019 JVIM systematic review found the effect on acute gastrointestinal disease in dogs limited and possibly clinically unimportant, and benefits appear strain- and context-specific: in one shelter trial SF68 significantly reduced diarrhea in cats but not in dogs.
