Oreo

Oreos do not contain any animal-based or animal-derived products however, they may be made in a setting where other animal ingredients are present. No animal products or byproducts are used to make Oreo cookies, however, which means that the product itself is vegan.

Traditional Oreos are made with wheat flour which contains gluten. Therefore, classic Oreo cookies are not gluten-free. There are a few alternatives that make products similar to Oreos if you're looking for something with a similar flavor or texture without the added gluten. Always read product ingredient labels carefully to confirm whether or not they contain gluten or ingredients that may contain gluten.

Oreos are not made with any dairy products however, cross-contact may be present. This occurs when the cookies are made in a factory where other products containing milk are made. When the Oreos are made in the same factory, there is a good chance that they could contain trace amounts of dairy. If you are extremely sensitive or highly allergic to dairy products, then this is something to take into consideration. Otherwise, Oreos are generally dairy-free.
