Yes, frozen fruits can be used with a NutriBullet. In fact, they can enhance the texture and flavor of your smoothies, providing a refreshing twist. However, it is recommended to add a bit of liquid, such as water or juice, to help facilitate blending. This is especially important when working with frozen items, as they can be quite hard and may require additional liquid to achieve the desired consistency. If using particularly tough or dense frozen fruits, you might want to blend them in smaller batches to ensure that the NutriBullet operates efficiently. Always refer to the guidelines provided in the NutriBullet manual for specific instructions related to blending frozen ingredients, as this can vary depending on the model being used.
