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.

What is the difference between SiS GO Hydro and the SiS GO Electrolyte products?
SiS GO Hydro contains a specific 300mg of electrolytes, which are lost through sweat. They are simply dissolved in water, with a minimal 0.8g carbohydrate and virtually no calories. Use SiS GO Hydro to hydrate before exercise and during sessions lasting under 90 minutes when energy is not needed. GO Electrolyte contains 36g of fast absorbing carbohydrate so is best for when energy is also required.
What is the difference between SiS GO Hydro + caffeine and the GO Electrolyte products?
SiS GO Hydro + Caffeine contains a specific 300mg of electrolytes, which are lost through sweat. Caffeine is added to provide extra mental stimulation. They are simply dissolved in water, with a minimal 0.8g carbohydrate and virtually no calories. Use SiS GO Hydro + caffeine to hydrate and provide a mental kick before exercise and during sessions lasting under 90 minutes when additional energy is not needed. GO Electrolyte products do not contain caffeine but do contain 36g of fast absorbing carbohydrate so are best for when energy is also required.
What are the benefits of caffeine?
Caffeine has been shown to increase endurance performance by providing a mental boost by improving alertness and concentration.
Does Caffeine have a side effect?
Everybody's sensitivity to caffeine can vary, so it should always be tried in training and in small doses initially. Caffeine has also been shown to increase urine volume, so keep hydrated.
Does this make a fizzy drink?
When your drop the hydro tab in the water, it will fizz until fully dissolved. After this you are left with a still electrolyte drink.
Can I mix this with GO Electrolyte or GO Energy to get all the benefits?
No, as this would provide too much sodium, beyond the optimum levels.
Do they taste salty?
No, they are flavoured in berry and lemon flavour.

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.
