No, any blender that can handle pieces of fresh fruit or veggies will work fine. Any basic blender will do – we’ve used NutriBullet, Ninja, Vitamix, etc. to mix our Microbiotic Kitchen shake base with liquid and pieces of fruit and veggies.
If you are adding frozen fruits or vegetables, you may need to defrost large pieces unless you have a heavy-duty blender. Plus, chopping fresh fruits and vegetables into manageably sized pieces is recommended for whichever blender you use.
