Oronamin C

Oronamin C Drink (オロナミンCドリンク, Oronamin Shī Dorinku), produced by Otsuka Chemical Holdings Co., Ltd., (distributed and sold by Otsuka Pharmaceutical Co.) is a carbonated beverage available in Japan. It is commonly called Oronamin C or Oronamin. Its name is similar to the Takeda Pharmaceutical Co. product "Arinamin" and its name comes from Otsuka's own Oronine H Ointment and its main ingredient, vitamin C. Oronamin C was named after the Oronine H Ointment in hopes that it would prove to be equally successful.
