Science in Sport Hydro Electrolyte Tablets - Four Key Electrolytes and B Vitamins - Sugar-Free, Vegan & Gluten-Free Sports Hydration - Cola Caffeine - 20 Effervescent Tablets (Pack of 8)

When plain water just won't cut it, Science in Sport has got you covered! The pill dissolves beautifully. Leaving a delicious source of nutrients and electrolytes in its wake. It really doesn't affect my sleep quality. No stomach issues either. Its cheap enough to subscribe to a bottle monthly. The high quality is that good that I have multiple bottles!

Ordered this several times now. Tastes good, helps with hydration and energy during or after sport and gym.

This is a great product and has actually helped with my dehydration headaches ( I do take another coconut electrolyte drink too) so I technically get 2 a day instead of the 1 and that helps me a lot. This product does take effect quite quickly and at less than £5 special price it's definitely worth the price, it arrived quickly too which was a nice surprise. My only downfall with this is the cola flavour, it smells just like cola and does taste of cola to some degree but very sickly and synthetic cola taste, ( of course that's to be expected though) so I would personally recommend the citrus flavours, as those are way nicer in my opinion, but it's nice to try a new flavour.

Great item thank you very fast delivery very easy to use starting to have more energy lovely appearance great taste

Looks like dirty water, and tastes like flat cola, even in sparkling water All that said, I think it did do what it says (although i can’t say if i felt more “caffeinated”), but there are better flavours from SiS, and the appearance of the water does make you think if you really want to be drinking it!

I get a lot of headaches and one of the things that gives me a headache is walking / cycling when it's very hot (ie clearly dehydration related). The summer of 2022 (when temperatures stayed above 30 C for several weeks) was very tough so I thought about what might help and, after looking at various rehydration products, I gave these a try. I haven't had a dehydration headache since (now there's a claim)! What's more; I noticed I didn't get the weariness I associate with getting very hot (again clearly dehydration) any more. I always drink a lot of water when I'm walking / cycling in the heat (my target is 500ml per half hour, which is quite a lot) so my problem wasn't lack of water, I believe it was loss of salts. I now put one of these tablets in my first (500ml) bottle of water when it's warm outside, and if it's hot I put another tablet in my second bottle as well... it makes my exercise / journey less weary and therefore more enjoyable (and did I mention NO headaches). The cola taste is OK (not great but not awful - although my 22 year old son preferred the berry flavour). All in all: great product, which I buy routinely now.

As others have noted it is like a flat cola. The taste takes a bit to get used to. It is not a bad taste. Here in Australia the normal water bottles are 600ml, so just take a dip or two of water, break the tablet in half (so it fits in the opening), wait a few minutes and enjoy. Caffeine is 75mg about half the strength of an energy drink (based on 500ml. Same caffeine as a 250ml red bull) or the same as a cup of coffee. Since it is sugar free you don't get a crash from it. Preferable to either Powerade or Gatorade. Less sodium, but more of other minerals - calcium, magnesium and potassium. Summary - great for hydration and provides a mild caffeine boost that is not overwhelming. Sugar free so no crash. Flavour takes some getting used to, but it isn't bad I will buy this again. This is my 4th order. 1st was 3 tubes, 2nd and 3rd were each 5 tubes. This last order was 8. Bear in mind I'm shipping to Australia so I need to keep the orders cost effective.

These work really well for hydration and training. The cola flavour is okay — not amazing but easy enough to drink. Dissolves well and the caffeine gives a nice boost.

Excellent product

Excellent et pratique, j apprécie beaucoup le goût qui est très désaltérant.

Good product and very refreshing

Im a road cyclist and use this product everytime I ride. Its easy to drink and tastes like cola, so it has that tendency to sit in your mouth with its sweet residue and flavour, but it your ride often, and on long distances I take plain water too, so that I can change the taste in my mouth. However its worth noting that ive had other flavours too and they all do it, not just the Cola.
