Review: A valuable item whatever the weather or level of fitness - Superb quality and flavour. Dissolve quickly too. I top up my electrolytes really easily with 1 a day- great before having a blood test too
Review: Superior taste, great absorption. - Still the absolute best in electrolyte replacement for my lack of bowel absorption. 2 tablets a day in a one litre bottle for the day, great refreshing taste. Can be expensive, look out for offers, it’s sometimes better to buy them in single tubes then other times a full box, just do a good check. As a brand, I trust and like their products immensely.

## Questions & Answers

**Q: Why are there artificial sweeteners?**
A: Not being the manufacturer, I don’t know.  I would prefer it if they did not use them.  Of more concern to me, though, is that as well as the sweetener sucralose, they are also using sorbitol, though as a humectant (preserving moisture) rather than a sweetener.  Surely we are still consuming it though?

**Q: What's the equivalent of one tablet dissolved into 500ml of water to just drinking water? Is it like drinking 1, 2, or 3 litres water?**
A: There is no equivalent. SiS (or any other sports electrolyte formula) restore the electrolyte balance in your body. When you sweat you are losing more than just water, you are also losing 'salts' (big simplification!). Just drinking plain water during sport does not rehydrate you properly, which is why people add products such as this. In fact if you start to consume large volumes of water you will make the situation worse and could end up with a condition called Hyponatremia (low sodium concentration in the blood). Bottom line if you are doing exercise which causes you to sweat then re-hydrate properly using an electrolyte supplement added to water... With or without carbohydrate depending on your calorific needs.  edstivala.com

**Q: why this price is so sick? £7? really?! in Lidl I can pay around £4.5 per tube/20tabs.**
A: I got mine for £5 online but it seems to vary for no good reason

**Q: Can you take them in the evening?**
A: Yes

### ⭐⭐⭐⭐⭐ A valuable item whatever the weather or level of fitness

Superb quality and flavour. Dissolve quickly too. I top up my electrolytes really easily with 1 a day- great before having a blood test too

### ⭐⭐⭐⭐⭐ Superior taste, great absorption.
*by R***D on 29 May 2026*

Still the absolute best in electrolyte replacement for my lack of bowel absorption. 2 tablets a day in a one litre bottle for the day, great refreshing taste. Can be expensive, look out for offers, it’s sometimes better to buy them in single tubes then other times a full box, just do a good check. As a brand, I trust and like their products immensely.

### ⭐⭐⭐⭐ Great to have, gives you the required minerals
*by S***M on 17 July 2024*

I have bought this for myself as I needed to go for runs with this. It comes in a plastic tube and the appearance are of a tablet form where you can break them into smaller chunks and drop them in your water bottle. They dissolve quite quickly and the taste is good, not the best. The performance is apparent after a while and it’s a lot of value for money. I don’t get any muscle cramps when using these, and i’m glad they work. Overall, these are great to have.
