<<Disclaimer: Verify this information before applying it to your situation.>> I want emphasize that I said, "All maltodextrine made in the UNITED STATES is made from corn." Be sure to check the sources of maltodextrine. It's possible that some is actually purchased from Canada or elsewhere, where it can be made from barley or wheat and marketed in American made products.
