Dietary Supplement Non-Bitter Zero CaloriesNuNaturals uses our special, highly concentrated Stevia extract, NuStevia, from which the bitterness of the extract has been removed. Erythritol is produced from corn. It is used in our NoCarbs formula to make it easier to measure the Stevia extract. It works synergistically to enhance the taste of Stevia. NoCarbs will have no effect on blood sugar levels and is safe for both Type I and II diabetes. NuNaturals uses plant-based natural flavors that help to make our Stevia products the best-tasting ones available. NuStevia is a natural plant extract.
