What it is made from

Made by reacting glycerol with fats or oils, which may be of plant or animal origin. The source is rarely stated on a label, so a product containing them cannot be assumed to be vegetarian without asking the manufacturer. This is the clearest case on this site where the additive name does not settle the dietary question.

  • Vegan status depends on the source
  • Vegetarian status depends on the source
  • May raise a halal question
  • May raise a kosher question

This is not an omission. What this additive is made from is not fixed — depending on the manufacturer it may be plant, animal or microbial in origin, nobody is required to say which, and the same product can change source between production runs. Ask the manufacturer if it matters to you; a label cannot answer it.
