These were recommended to me when I was working offshore.  In the Kazakh heat, you have to drink a lot of water, and a lot of water can get very tedious so quite a few of the guys out there use these tablets, primarily as a method of adding a bit of flavour, but they’re aimed at keeping you hydrated by replacing the electrolytes you lose when you sweat.  There are lots of different brands out there, and just as many different flavours.



  • Tasty
  • Rehydrating
  • Compact and light


  • Expensive
  • Easy to get on the internet, not quite so easy to get from a shop

I bought the Zero Highs Citrus tablets, and I paid about £5 from Go Outdoors.  For that, you get an 80g tube containing 20 tablets; the suggestion on the tube is for a strong drink, you need 2 tablets for 750ml of water, or one tablet for 750ml of water if your prefer it weaker.

All you do is pop the lid off the tube and drop a tablet in your water; they’re effervescent, so they fizz as they dissolve, so you need to make sure that you don’t seal your bottle tightly, otherwise you’ll get a big pressure built up, but that’s it, job done, hydration drink made. I had a 600ml sports bottle, and I found that 2 tablets was very strong, and I didn’t really like it, plus you’ll burn through your tablets very quickly.  1 tablet produced a very refreshing drink.

The citrus ones were pretty nice, I could definitely taste the lemon and lime, and I’ve also tried the berry ones, which were equally nice.

I’m definitely going to be taking them with me again, they’re light and take up very little space, which is perfect for cycle touring or backpacking; they make water more interesting and therefore more likely to drink more, and they’re more effective at hydrating you than water alone.  I would however suggest getting the online, you can get them much cheaper than in stores and there is a bigger selection of flavours.
