Science in Sport Hydro Electrolyte Tablets 20 pcs. Cola + Caffeine – Vegan & Gluten-Free, with Sodium, Calcium, Potassium & Magnesium for Balanced Electrolyte Levels (Packaging May Vary)

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.

I'm iffy on these drinks and this one is ok. You get fluids and a shot of caffeine. I didn't notice any excess urination with the drink, though the cola flavour is mild but not unpleasant. 8/10

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.

Great,good idea,handy,tasty,simple,healthy,convenient,good price tganks

Tastes a bit like watery cola, even when made up to spec, but otherwise does the job.

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.

I use these to help keep hydrated during a long ride out on my bike and they are perfectly suited for the job. Of course you could use these for other sport such as running or gym where replacing lost fluids and hydration is important. If you're looking at these then you probably already know that keeping hydrated is not as simple as just consuming lots of water. Your body needs to replace lost minerals such as sodium as well as water in order to re-hydrate. That's where these come in. They contain a blend of electrolytes required to re-hydrate. The added caffeine is a great bonus too. They dissolve really well, and the tube is small enough to carry around in your saddle bag if you're using them for cycling. I typically use two in my 750ml bottle, this helps with the taste too as its quite weak. The taste is obviously not the point of these, but it helps when they taste nice. I've always used Cola and they taste just fine, a bit like diluted cola. If you use different size bottles it's important to note that they are easy to break up should you require one and a half or different amounts based on your bottle's capacity.

Not a bad cola flavour for the price, but I've had better

Excellent product

le goût est vraiment bon

Cuando haces tiradas largas y no tomas café antes de entrenar,esto vale por 2 te hidrata y te da ese chute de cafeina

Sapore gradevole e piacevolmente diverso dai soliti limone, arancia, ecc. Come integratore isotonico sembra funzionare bene, inoltre, il formato in tavolette ha il vantaggio della trasportabilità, così da poterlo aggiungere facilmente ad ogni ricarica della borraccia. Considerato che con un tubetto da 20 compresse si preparano 10 liti di bevanda il prezzo è tutto sommato allineato a quello degli altri isotonici. La caffeina è presente in quantità molto modeste e per un normale bevitore di caffè è pressoché ininfluente.

I work 12 hour shifts, out of all the energy drinks and coffees ive had this product works consistently well and also replenishes your electrolytes so you feel refreshed. I carry it on me in a side pocket and pop a few tablets when I need it during, usually post lunch and during the last 3 hours or so of work. It tastes good to me, like a flat coke.
