- Potions: are used to heal your Pokémon's HP as
you battle them at Gyms throughout your city. A basic Potion
restores 20 HP. They can be found at PokéStops, bought in the Shop,
and received as rewards for leveling up. You don't get them until
level 5, since you can't battle at a Gym until level 5 anyway.
- Super Potion: Super Potions are used to heal
the HP of your Pokémon by 50 points. Super Potions can only be
found at PokéStops after level 10 or received as rewards for
leveling up.
- Hyper Potion: The grandaddy of the Potions
game (at least in Pokémon Go), is the Hyper Potion, which restores
a Pokémon's HP by 200 points. Hyper Potions are rewarded to you at
level 15 and can be found at PokéStops after that, though they're
pretty hard to come by. Use them wisely!
