The Nutri Ninja Blender is a brand that operates under Euro-Pro Operating LLC, while the NutriBullet is manufactured by NutriBullet, LLC. The names of these products are similar, but they are made by different companies. Both products offer the ability to make healthy shakes and drinks.
The NutriBullet is billed as an extractor, not a blender, with the company website indicating that the appliance breaks down ingredients to get optimum nutrition. The Nutri Ninja makes similar promises, but still refers to its ability to work with other Ninja blender products. Both the NutriBullet and NutriNinja break down ingredients into a cup rather than a pitcher, so users can drink directly out of the cup the ingredients were mixed in.
