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

  • • Simply drop in water to provide a high electrolyte drink
  • • High in sodium to help promote hydration
  • • When hydration is required without the added calories
  • • Contents: 20 x 4.2g Tablets
 

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.

Benefits

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.

I've been using these for many years and they are a great taste and do the job well. Other similar products are too sweet or sickly. These just the right amount of flavour. I just won't buy direct in future due to shipping problems with SiS and will prefer to use bigger suppliers with more organised shipping operations.
