There are a few ways to get Nanab Berries in Pokemon GO—alongside other berry types and rewards.
Niantic Labs has implemented several types of berries to help trainers achieve their goals in Pokemon GO. Veteran trainers will know that berries are far from a new mechanic in-game. Almost every main series game features berries, whether it's the ability to grow them in the Hoenn region or turn them into Poffins in Sinnoh. Additionally, trainers have been known to give them to Pokemon for battle, giving their team an extra edge.
Here's everything there is to know about Nanab Berries.
Nanab Berries in Pokemon GO
Niantic describes this berry by its use, writing, "Feed this to a Pokémon to calm it down, making it less erratic."
Nanab Berries are the pink banana bunch-shaped berries that cause "confusion" when fed to a Pokemon in Pokemon GO. They stop a Pokemon from abruptly moving around so frequently, making them easier to catch.
Some trainers report that these are best spent on Pokemon who hover above the ground such as Zubat, Woobat, or Magnemite.
Trainers can start finding Nanab Berries at level four. Typically, they can be found by spinning PokeStops and Gym discs, but are also known to be rewards for leveling up.
In main series games, Nanab Berries were first introduced in Generation III. They could be harvested, re-grown, and then fed to Pokemon to increase their cuteness. It is known to be sweet but increases both sweet and bitter flavors in PokeBlocks.
