Consumer Advice
This is a natural form of vitamin E (l-alpha-tocopherol), used in food as an antioxidant to stop oils and foods from going rancid, and it is also a nutrient the body needs. It is typically extracted from vegetable oils such as soybean oil, contains no animal ingredients, and is safe for vegan, halal and kosher diets. It has a very high safety margin and is not a common allergen; refined tocopherols are extremely unlikely to trigger soy allergy.
