Controversial ingredients · 1
- sodium seleniteSynthetic selenium source. Selenium is essential, but sodium selenite has a narrower safety margin than organic alternatives like selenium yeast. Better-formulated foods use the organic form.
Every flagged ingredient has a published basis (confirmed harm / regulatory action / precautionary). See methodology →

- 1brewers rice
Broken rice kernels left over from milling, usually destined for human beer-making. Cheaper than whole or even white rice. Same carbs, less nutrition than the brown version.
- 2fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid.
- 3hydrolyzed soy protein
- 4fiberdried chicory root
Natural prebiotic. Feeds beneficial gut bacteria. The same compound (inulin) used in human gut-health products.
- 5othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 6vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
- 7fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
- 8fiberpea fiber
Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.
- 9sodium aluminosilicate
Anti-caking agent that keeps powder ingredients flowing. Functional, not nutritional.
- 10mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 11supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 12fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 13mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 14supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 15n-butyric acid
- 16supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 17mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 18l-tyrosine
- 19supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 20gla safflower oil
- 21marigold extract
- 22mineralzinc proteinate
Zinc bound to protein for better absorption. The premium form of the mineral, versus zinc oxide which sits cheaper on the label.
- 23zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 24mineralmanganese proteinate
Manganese bound to protein for better absorption. The chelated form most premium brands use.
- 25manganous oxide
Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.
