Owned by The Coca-Cola Company, Aquarius is a prominent sports drink brand first introduced in Japan in 1983 as a response to the growing demand for functional, hydrating beverages. Originally formulated as a grapefruit-flavored isotonic drink designed to replenish electrolytes and fluids lost during physical activity, it has since expanded its presence across Asia, Europe, and South America, becoming a staple in the fitness community. The brand distinguishes itself through a focus on “active hydration” and a lighter, less sugary taste profile compared to traditional sodas, often serving as the official beverage for major international sporting events like the Olympic Games. Today, the Aquarius portfolio has evolved beyond simple rehydration to include functional variants fortified with vitamins, minerals, and zero-calorie options, catering to a broad demographic of health-conscious consumers and athletes alike.
