All of the Nutri-berries products deliver outstanding nutrition. What they do better than pelleted diets is that they get birds to eat them. Nutri-berries are evidently fun foraging, interesting to hold, and taste good. My Indian ring-necked parakeets are crazy about the tropical fruit flavor, and my cockatiels and green-cheeked conure love them, too. (It is often not easy to get cockatiels to eat fruit. They also get cockatiel Nutri-berries.) Even my Senegal doves like them. The nutrition is as good as the best pellets, and the birds enjoy eating them.
