Suntory PepsiCo Beverage Thailand has introduced Suntory Hy! Water‑Lock, a new functional hydration solution built on Japanese research and technological expertise.

Developed by Suntory Japan, the Hy! Water‑Lock technology is designed to help the body retain hydration for longer. Rooted in the concept of Hydration Science, Suntory’s research team studied the body’s water absorption mechanisms in depth and discovered that effective hydration depends not only on the amount of water consumed, but also on the balance of minerals and the optimal osmolarity (solute concentration) that supports absorption.

To meet this need, Suntory developed the Water‑Lock formula by carefully balancing sodium and sugar at optimal levels. This precise formulation enhances the body’s ability to absorb water and helps maintain hydration for longer compared to plain drinking water. The beverage is further fortified with niacin (Vitamin B3) and infused with a crisp, refreshing yuzu flavour, making it both functional and enjoyable to consume throughout the day. Designed with modern lifestyles in mind, it is particularly suited for urban consumers who spend extended hours in air‑conditioned environments, where hidden water loss can occur without notice.

Suntory Hy! Water‑Lock leverages the untapped potential of ‘invisible water loss,’ addressing the needs of consumers who spend long hours in air‑conditioned environments and may not realize that dehydration can occur even without obvious signs.

This approach sets Suntory Hy! Water‑Lock apart from competing hydration brands, which typically emphasize the importance of staying hydrated for fitness and active lifestyles, rather than focusing on everyday scenarios such as invisible water loss.
