Vitamin E and tocopherols
Research-supported
What it is
Commercial vitamin E (tocopherols) used as an ingredient or preservative is typically extracted from soybean oil. Sunflower-derived tocopherols exist but are less common and usually called out on the label when used.
Relevant concerns
- Soy
Tocopherols are most often soy-derived unless the label specifies an alternative source (e.g., "sunflower-derived vitamin E").
