The best blender for Shakeology is the Nutribullet because it chops up everything and blends well. All other blenders will leave pieces in the shake and often lead to clumps because they only use one blade; whereas a Nutribullet has two blades that chop all your ingredients then, in turn, goes into a spinning motion that forces the pieces together. This means you get all of your nutrients immediately with absolutely no grit or chunks. It's an excellent way to start drinking shakes!
