Frequent Asked Questions
Flightsu is an electrolyte formula specifically developed for pilots and cabin crew to support hydration, focus, and energy at altitude.
At altitude, you continuously lose moisture and electrolytes. Traditional electrolyte supplements are designed for athletes who lose fluids through sweat. The conditions inside an aircraft cabin are completely different. That’s why Flightsu has been specifically developed for this environment.
Flightsu is not a replacement for water, but a smart addition to it. It helps optimize how your body absorbs fluids, while its fresh taste acts as a natural reminder to drink more often. This makes regular water intake easier, more consistent, and more natural throughout the day. The result is better and more stable hydration over time.
Yes, it is suitable for regular daily use.
Fresh and light, without sugar. Subtle, like a hint of lemon in water rather than a heavy lemonade.
Otsuka Pharmaceutical has conducted research on hydration during long flights and its effects on the body. In a study with 40 participants, those who consumed an electrolyte drink retained significantly more fluid than those who drank only water. In addition, their blood viscosity remained lower and circulation in the legs was improved.
