NutraBio is just getting started with our NutraBio Naturals line! As we always do we make our products better and better, cleaner and cleaner. That is our promise to you and we always stay true our values. In typical NutraBio fashion, we have made our New NutraBio Naturals Grass Fed Whey Isolate even cleaner by removing the Xanthan gum. This product is now gum free and as clean as any whey on the market if not cleaner.
