The NutriBullet is a popular blender that can be used to make smoothies, shakes, and other types of drinks. It is also often used to blend protein powder into drinks. While the NutriBullet can be a good option for blending protein powder, there are some things to keep in mind. First, it's important to choose a protein powder that is compatible with the NutriBullet. Some protein powders are designed to be mixed with water, while others need to be blended with milk or another liquid. Be sure to read the directions on your protein powder to see what is recommended. Second, you'll want to add enough liquid to the NutriBullet so that the protein powder will blend properly. Again, refer to the directions on your protein powder to see how much liquid to use. Third, you may need to experiment with different blending times to get the consistency you're looking for. Start with a shorter blending time and increase it if needed. Finally, keep in mind that the NutriBullet is not designed for making large batches of protein shakes. If you plan on making shakes for multiple people, you may want to consider a larger blender such as a Vitamix or Blendtec.
