IAMS™ PUPPY SMALL BREED

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

• Beet Pulp · ingredient 6Well 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 7Well 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 25Well 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 2NeutralA 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.
• Brewers Rice · ingredient 4NeutralAn AAFCO-defined ingredient consisting of the small, broken fragments of rice kernels separated during milling. It is a digestible carbohydrate and energy source nutritionally similar to other rice; the 'brewers' name reflects how the fragments are sourced, not lower nutritional quality.
• Corn Gluten Meal · ingredient 8NeutralThe 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.
