E307AntioxidantLow concern
Alpha-Tocopherol (synthetic)
In plain words
The short version
The synthetic single-isomer form of vitamin E — used in oils, infant formula, and supplements.
Why it's green
It's widely considered safe at the amounts used in food, so we mark it green. The Safety section below has the details.
Safety profile
ADI not specified — well-tolerated. The synthetic dl-form has lower biological activity (~74% of natural d-α-tocopherol per the IU conversion factor), so larger doses are typically required for equivalent vitamin-E effect. Antioxidant performance is similar.
