Common questions
What are mixed tocopherols in dog food?
Natural vitamin E compounds used as an antioxidant preservative to prevent fat rancidity. The "natural" alternative to synthetic preservatives like BHA, BHT, and ethoxyquin. Mixed tocopherols also contribute to the food's vitamin E nutritional content (the alpha-tocopherol fraction specifically).
Are mixed tocopherols safe for pets?
Yes — FDA GRAS and AAFCO-approved at typical pet-food inclusion levels, with no documented safety concerns. The main trade-off versus synthetic preservatives is shelf life: mixed-tocopherol-preserved kibble typically has 6-9 months' effective preservation versus 12+ months for BHA/BHT-preserved equivalents. Most premium brands pair mixed tocopherols with rosemary extract to extend shelf life naturally.
