About Hydro Tablets
Hydro
Hydro is designed to ensure you are effectively hydrated to produce your best performance. As an effervescent tablet that readily dissolves in plain water, it represents a highly practical approach (simply drop one tablet in your 500 ml water bottle) without the calories.
Hydro meets your sodium requirements at a specific concentration (30mmol/L) that is scientifically proven to produce superior hydration compared with water alone. It was developed to keep the British Sailing team optimally hydrated at the 2008 Beijing Olympics. Simply drop a tablet into water for effective hydration, with virtually no calories, before and during sports.
Key Features
Hydro + Caffeine
The addition of 75mg of caffeine has been repeatedly shown by sport scientists to improve performance by providing both a physical and mental boost.
Electrolytes including sodium, potassium and magnesium are lost through sweat and need to be replaced in order to help the body maintain fluid balance, alongside an appropriate fluid intake.
