Typical source

Synthetic or vegetable oil

Plain-language explanation

E307, or alpha-tocopherol, is a form of vitamin E that acts as an antioxidant to prevent food from spoiling. It is commonly sourced from vegetable oils like soybean or sunflower oil, which are naturally halal, but can also be made synthetically. Major halal certification bodies consider E307 halal when derived from plant sources or synthetically produced, but its status would be questionable if derived from non-halal animal fats, which is rare. Therefore, it is generally accepted as halal unless the source is specifically from non-halal animals.
