( キトサン Chitosan )
Zinc (キトサン Chitosan) is one of the Vitamin items. It, along with the PP Max, made their first appearance in Generation III, rather than in Generation I with the rest. In Zinc's case, it is because, although Special was split into two stats in Generation II, Calcium still raised both stats that had comprised the Special stat: Special Attack, which it still increases, and Special Defense, which Zinc was made to increase.
Zinc, similarly to other vitamins, raises a base stat in the Pokémon it is used on; in its case, it raises the Special Defense. In more accurate terms, it raises the Pokémon's Special Defense IVs by 10, but only up to 100 Special Defense IVs.
