Not necessarily. Although our Xylitol is derived from non-GMO corncob, by the end of the extraction process there are no proteins left over to provide allergens that may be the cause of your corn-based reactions. Also, most people are actually allergic to corn kernels, as opposed to the cob, so there is a chance that our Xylitol may be suitable for your needs. As with all allergies, however, please consult your health practitioner for more information.
