Is Soy Protein Powder gluten free?

Pure soy protein powder is gluten free, as it is made from soy beans which do not contain gluten protein. Gluten protein only occurs in grains like wheat, rye and barley. However please check the ingredient list when reviewing a soy protein powder product as some additives can contain gluten.

Is your product totally gluten free, but you still react? Soy protein powder can sometimes suffer from cross contamination with products which contain gluten. Farmers often rotate wheat and soy fields. Crops after harvesting can also be processed and stored with the same equipment. Products can also be processed with the same equipment in factories. Cross contamination can happen, so if you still suffer symptoms from gluten after using a particular product you can try a different product to see if side effects cease.

Consider also that some people can have a soy intolerance in addition to problems with gluten.
