Product Uses
Recommended Usage

Consume 500ml of SiS Hydro 3-4 hours prior to your event with a further 250-500ml in the hours before starting. During exercise of a shorter length where carbohydrate intake is not necessary, consume 500 ml of SiS Hydro per hour. If aiming to combine hydration and energy delivery, consume SiS GO Electrolyte with the SiS GO Gel range.

Directions for Use

Add 1 SiS Hydro tablet to 500ml of water and let it dissolve. Once prepared consume within 24 hours. Do not consume more than 4 tablets per day.


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. SiS 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 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.


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.

Solo questione di gusti... Io preferisco gli altri..

Paolo Tarondo

Super prodotto, toglie la sete e non da alcun fastidio


Utili da portare e aggiungere nella borraccia durante gli allenamenti. Forse un po' meno frizzante sarebbe meglio, ma rimane comunque gradevole

Lorenza Sabini

Sempre il massimo per l’idratazione!

Prodotto ricevuto in omaggio lo sto ancora provando.. comunque comodo da portare per riempire la borraccia di sali
