There is probably nothing more important to an athlete than consuming water.

DR Susan Kleiner, renowned sports nutritionist, has described water as the most critical nutrient for growth, development and health. Indeed, water comprises:


• 45-70% of the entire body

• 76% of the brain

• 82% of the blood

• 90% of the lungs


Good hydration levels have been shown to greatly reduce the risk of developing urinary tract stones, various cancers and problems with the heart’s mitral valve.

In a sporting environment the very best case we can hope for when in a dehydrated state is a decrease in performance, at the very worst, severe illness and death.
