About 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.

Berry flavoured electrolyte mix with natural elderberry extract and added sweetener in 20 tablet pack.

Suggested Use

During moderate to intense exercise, we can produce up to 2 litres of sweat per hour depending on the environmental conditions. Sweat contains vital electrolytes, including sodium. Sodium is the most important electrolyte as it helps to stimulate thirst, improve taste and promote absorption and retention.

If fluid and electrolyte losses are not replaced, dehydration occurs which is a major cause of fatigue. Once dehydrated, our body temperature rises; our heart rate increases; we deplete carbohydrate stores quicker and we perceive the exercise to be more intense. GO Hydro can help prevent this, with the aim not to lose more than 2% of our body mass.

What is the difference between SiS Hydro and the SiS GO Electrolyte products?

SiS 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 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.


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, Lemon, Pink Grapefruit, Strawberry & Lime and Pineapple & Mango flavour.
