Pocari Sweat Ion Supply Drink

Pocari Sweat is a major functional beverage brand that originated in Japan. It was conceptualized and developed by Otsuka Pharmaceutical and first launched in 1980. The drink was famously inspired by a researcher's experience with dehydration during a business trip to Mexico; after seeing doctors drink intravenous (IV) solutions to rehydrate, the idea of a 'drinkable IV' was born. The formula was designed to mimic the natural electrolyte balance of the human body for rapid absorption.

While the brand was founded in Japan, its massive popularity across Asia has led to a decentralized manufacturing network. Today, the product is manufactured in several countries including Japan, Indonesia, South Korea, China, and Vietnam to serve local and regional markets. The brand is a core part of the Otsuka Holdings portfolio, maintaining its original pharmaceutical-standard research and clinical backing while operating as a global consumer staple in the hydration and wellness category.
