Trader Joe’s marshmallows are not vegan. The ingredients list sugar, corn syrup, gelatin, and flavorings.
Gelatin is made from animal collagen and is not suitable for vegans. The other ingredients are all derived from plants, but they may have been processed with animal-derived ingredients.
Some vegans choose to avoid processed sugars because of the possibility of bone char being used in their production. Bone char is a type of charcoal that is made from the bones of cattle. It is used to process sugar to make it white. While most sugar companies have stopped using bone char, there is no way to know for sure if it was used in the production of the sugar in Trader Joe’s marshmallows.
The bottom line is that Trader Joe’s marshmallows are not suitable for vegans. If you are looking for a vegan-friendly marshmallow, there are many brands that make vegan marshmallows using plant-based gelatin.
