Is E307 (synthetic tocopherol) halal?
E307 is uncertain. Synthetic alpha-tocopherol can be produced by routes our reference table treats as fine, or by methods that use alcohol in fermentation. The label does not say which manufacturing route was used, so the additive stays mashbooh.

What E307 (synthetic tocopherol) actually is
E307 is vitamin E (alpha-tocopherol) made by chemical synthesis rather than extracted as a mixed tocopherol concentrate from oils.
It is used as an antioxidant to stop fats going rancid — in oils, cereals, infant foods and supplements — and may appear as tocopherol or vitamin E rather than the E-number.
Why synthetic does not automatically mean clear
Our reference description is direct: sometimes the synthetic materials used are halal; sometimes methods of fermentation with alcohol are used. That fork is why the status is doubtful rather than a blanket pass or fail.
Do not assume every vitamin E on a label is this entry. Mixed tocopherols from plant oils are a different additive family; our table marks E306 (tocopherol-rich extract from soya, rice germ, wheat germ, maize and green leaves) Halal, with a review note that every named source is a plant. E307 is the synthetic alpha form with the alcohol-route ambiguity.
As with other process doubts, an unmarked code cannot tell you which factory route supplied your pack.
How to check it yourself
- Halal-certified foods and supplements have had vitamin E sources confirmed.
- Prefer products that specify natural vitamin E, mixed tocopherols from named plant oils, or carry a vegan mark when you want to avoid the synthetic-route ambiguity — and still check the exact additive if the pack only says vitamin E.
- Ask the brand whether their tocopherol is E306-style plant extract or synthetic E307, and which synthesis route they use.
Where you'll run into it
Vegetable oils and margarines as antioxidant, breakfast cereals, infant formula, vitamin E supplements, some snack foods with added fats.
Common questions
Is vitamin E always uncertain?
No. Plant-extracted mixed tocopherols (E306 in our table) are marked Halal. E307 is specifically synthetic alpha-tocopherol with a possible alcohol-fermentation manufacturing route.
Is this the same as E1510?
No. E1510 is ethanol listed as an ingredient and is haram. E307 may involve alcohol in a manufacturing method; that is why it is uncertain, not automatically haram.
Does *dl-alpha-tocopherol* mean synthetic?
Often yes — the dl- prefix commonly signals synthetic vitamin E. It is a clue to check, not a final verdict on the solvent route.
