Is xanthan gum suitable for vegetarian?

Yes. Xanthan gum is a fermented carbohydrate that is used in many gluten-free products as a thickener or emulsifier. It is also typically used as a stabilizer in cosmetic products. Xantham gum can be derived from wheat, soy, corn or dairy. If you are allergic or sensitive to gluten, make sure that the package specifies that it is gluten-free.
