6 ingredients in this list are ones we hold sourced evidence on , and none of them is contested in the veterinary literature.
- Beet Pulp · ingredient 7Well supportedThe fibrous material left after sugar is extracted from sugar beets, included as a moderately fermentable fiber source (commonly around 5 to 7.5% of the diet). Controlled feeding studies show it supports firm, good-quality stools and short-chain fatty acid production without impairing overall nutrient digestibility, so the 'cheap filler' characterization is not supported by the evidence.
- Mixed tocopherols (natural vitamin E) · ingredient 9Well 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.
- Rosemary extract · ingredient 23Well supportedA plant-derived natural antioxidant (active compounds carnosic acid and carnosol) used to slow fat oxidation, frequently chosen as an alternative to synthetic preservatives. It is an authorized food antioxidant in the EU (E 392); JECFA established a temporary acceptable daily intake for rosemary extract expressed as carnosic acid plus carnosol.
- By-Product Meal (Meat / Poultry By-Product Meal) · ingredient 4NeutralA rendered concentrate made from clean, non-muscle parts of the carcass (organs, necks, feet, and similar), defined by AAFCO. It is more variable and lower-transparency than a named muscle meal, but it is not inherently unsafe or low-nutrition: controlled feeding trials in dogs report high protein digestibility (roughly 92-95%) for poultry by-product-based diets, and some by-product organs are nutrient-dense.
- Prebiotics (chicory root / inulin, FOS) · ingredient 15NeutralFermentable 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.
- Probiotics (live microbials) · ingredient 16NeutralLive 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.
Nutritional twins
Cheaper close matches
Verified foods with a closely matching label at a meaningfully lower cost per 1,000 kcal.
Label-composition matches only: same species, form, and growth stage; same primary protein where both are known; grain-free preserved; protein within 4 points and fat within 4 points, and estimated carbs within 8 points, on a dry-matter basis. Not a medical or quality recommendation.
The maker
Who makes this — and how they back it up
The five questions the WSAVA nutrition guidelines tell you to ask a pet-food company. Every answer is sourced or marked as an undisclosed gap — never guessed. This is the "is it made competently?" axis that star-rating sites skip.
Iams is produced at Mars Petcare's owned/operated Mattoon, Illinois plant.

Most pet foods are only "formulated to meet" AAFCO profiles (a paper calculation) rather than fed to real animals in trials — this is common, not necessarily a red flag.
