Product Information

GO Hydro (Berry) 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.

GO 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.

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 4.3g Tablets

Product Uses
Recommended Usage

Consume 500ml of SiS GO 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 GO 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 GO 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.

Good taste refuels my body with the things it needs during activity easy to take extra tablets when riding for 6-7 hours

Richard Smout

Great way to keep hydrated and enjoy a flavor instead of just water

Ian Baron

These work best for me on long rides

Adrian Hughes

Not as nice as the lemon, but when you ride this often you need a change.

Trevor Mackay

good stuff and bored writing the same thing

Alan Muskett

always liked the berry flavour, so no problems

joanna taylor

Subtle flavour, more satisfying than just hi-juice or water.

Matt Tomkins

Great taste! One that is very refreshing.

Barry Langton

Tastey and great for hydrating after a run

Tim Rogers

Exactly as expected. Recommended.

Silvester Aina

Like the taste and works in no time.

Neil Jones

Used to use the high 5 zero hydration tablets, but had problems with them being fizzy and getting shaken around on my bike. Tried a free sample of these sis tablets and they don't seem to have the same problem. Which was also an advantage when I walked the Yorkshire three peaks as I could use them in my hydration pack as well. Only downside is cost as I can usually buy the high 5 for 3 for £10 but have to wait for offers from Sis

Ian Sharpe

Great Stuff. Use these over in the middle east in 40 degree plus temperatures (I work outside) and keep a tube in my overalls. Great taste and dissolve quickly.

Nigel Rolfe

Great tasting product and dissolves quickly. Very handy to have the container!

Tastes great and works well. I use them on their own for short runs or rides or mix them with blackcurrant electrolyte powder drink for longer ones
