FORMULATED BY SCIENCE

Designed to support GB Sailing during the 2008 Beijing Olympics, HYDRO is designed to replace sodium - the key electrolyte lost through sweat, essential for maintaining body fluid balance. Added caffeine improves cognitive function to minimise the effects of fatigue.

SUPPORT THE SWEAT

Sodium is the key electrolyte lost through sweat.

Learn more

SUPPORT THE SWEAT

Between 200 - 2,000mg of sodium is lost per litre of sweat, depending on the environment and exercise intensity. Sodium helps maintain fluid balance and keep intermuscular cells hydrated. Consuming large volumes of water can dilute sodium concentrations in the body, making it essential to top up sodium levels whilst drinking water to maintain hydration.

HYDRO provides 870mg of sodium to help maintain body fluid balance to keep you prepared for exercise.

FOCUS AND ALERTNESS

Caffeine improves cognitive function during exercise.

Learn more

FOCUS AND ALERTNESS

Caffeine is a proven cognitive enhancer, shown to improve focus and reduce perception of effort. Consuming caffeine is shown to enhance several aspects of physical performance, including time to exhaustion, explosive power and repeated sprint performance.

Adding caffeine to a fuelling strategy during the later stages of exercise will reduce the effects of fatigue and help keep your mind sharp to make decisions.
