⚠ Controversial ingredient
An artificial color additive (Allura Red AC) used to enhance the visual appearance of pet food.
Provides no nutritional benefit whatsoever and is added solely for the visual appeal to human buyers, as dogs and cats have limited color vision. Multiple studies have raised concerns about behavioral effects in children, leading the EU to require warning labels on foods containing Red 40. Some animal studies have suggested potential genotoxicity, though results are debated. The FDA maintains it is safe at approved levels, but many veterinary nutritionists recommend avoiding artificial colors entirely.
