Doubtful — depends on source
E306 (Tocopherols / Vitamin E) is an antioxidant usually extracted from vegetable oils; most commercial Vitamin E is soy-derived and halal, but the carrier and source can vary, so it is treated as doubtful unless confirmed.
Tocopherols are a group of compounds that make up vitamin E, used as antioxidants to stop fats and oils going rancid. Food-grade E306 is normally extracted from vegetable oils such as soybean, sunflower or palm.
Recovered from vegetable-oil processing (deodoriser distillates) and concentrated. The tocopherols themselves are plant-derived, though any carrier oil used to dilute them can vary.
Tocopherols are generally from vegetable oils, which points to halal, but they are classed as doubtful because the carrier oil used with them (and, rarely, the wider process) can vary and is seldom stated.
