I have never really heard of Nutribiotic. However, it is awesome that this protein is entirely plant based and has no unnatural flavorings or color. With that being said, it is a better deal to get the 3lb tub over this tub. You will still be getting a good deal with this one, but it is a much better value to get the 3lb tub. I am a huge fan of plant based proteins because it never hurts to get off of dairy and animal products in general for a while. Also great for recipes.
