Here is a spot that has a list
of the names/ingredients in products that should be avoided by those on a Casein or Gluten free diet. Also you can find a list of names/ingredients that contain MSG for those who also need to avoid it.
Did you know that the FDA does not require some food addatives to be listed such as MSG and HVP to be specified in some cases. Some food manufactures may not be required to list all ingredients on products because the packaging is small!
IF IN DOUBT, DON'T PURCHASE THE PRODUCT!
