Nuun Electrolyte Tablets

by Dave Sherman

They Say - Nuun is leading the way in portable hydration with three drink options to keep you refreshed and replenished all day, everyday. All three are ideal to help keep you hydrated and to make the most of the water you drink.

  • Nuun Active Hydration drink tabs are portable, taste great, and deliver a fast-absorbing electrolyte blend without the sugar or waste of bottled sport drinks.
  • The electrolytes that your body needs: Each tube of Nuun contains 12 tablets. Each tablet makes 16 oz. of Nuun, and delivers 360 mg Sodium / 100 mg Potassium / 25 mg Magnesium / 13 mg Calcium
  • Nothing that you don’t: Less than 1g of carbs, fewer than 8 calories. No sugar. No high-fructose corn syrup. No artificial flavors or colors.
  • Good for the Earth: One tube prevents the manufacture of up to twelve 16oz plastic bottles from sugar-ADE sport drinks.

We Say – Electrolyte tablets aren’t a new thing, a few manufacturers now produce them in a variety of flavours. However they aren’t always a good thing so with this in mind team Trek and Run decided to test out Nuun’s ‘Electrolyte enhanced drink tabs’.

Nuun website describes how these tabs are “chosen & trusted by cyclists, triathletes, runners, swimmers, hikers, yogis, travellers, adventure racers, rowers, and many others ‘doing stuff’ while trying to stay properly hydrated” and as a self-confessed fitness fanatic who falls into almost all of these categories, I decided to put the various flavours through their paces in a number of situations.

But first a bit about the tabs themselves… a quick look at Nuun’s website shows the tabs are available in 9 flavours (lemon+lime, tri-berry, cherry limeade, lemonade, strawberry lemonade, kona cola, citrus fruit and tropical) and each flavour is available in tubes of 12 tabs with a recommended dose of 1 tab per 500ml bottle of water. Nuun’s website describes how “adding flavour and electrolytes to water can up your intake by 90% verses plain water as it fuels the subconscious drive to drink” so as someone who tends to find drinking ‘just water’ quite boring, I was interested to see how well this product would live up to its claim.

I was supplied with a couple of single serving sachets including lemon-lime flavour, and three 12-tab tubes; tri-berry, fruit punch, and finally cherry limeade which contained 40 mg of caffeine per 16oz (473ml) serving and this last one seemed particularly attractive to me (my early morning sessions always feel especially rewarding when they’re fuelled by a hefty dose of caffeine) so I was happy to see how this would help those times when I’d rather be wrapped up under my duvet still when I’m out pushing my lungs and body to their aerobic limit.

The first flavour I checked out was ‘Lemon+lime’ which I tested during a spin (static cycling) session and as a lover of 7up and sprite, this flavour didn’t disappoint. Although obviously the tabs didn’t provide the fizz you’d expect from your favourite soft drink, the flavour was there in abundance even though I’d used one tab in a 750ml cycling bottle, and it did the job of ensuring I felt hydrated through the entire 1 hour spin session.


Next I tested the Cherry Limeade flavour during a 7am swim session. Now I’m NOT a morning person so I tend to find these sessions incredibly tough, and this particular session involved 6 x 200m swims so I’d been fully expecting to feel drained after just a few sets. Thankfully though the drink seemed to help me through the session and although I wasn’t quite feeling ‘wired’ the way I usually would after a can of Monster or Relentless, I definitely enjoyed the flavour and felt the drink assisted me in powering through the gradually gruelling session.

My third test involved using a Fruit Punch tab during a short run and unfortunately I have to say I didn’t find this drink as palatable as the other flavours. As a thirty-something year old I have fond memories of the old ‘Barrett’s Fruit Salad’ chews so in my mind I was imagining a similar taste to this this drink, however I’ve also had a terrible experience with a fruit punch flavoured creatine powder drink and again I found this flavour un-stomachable. This may be down to my own taste-buds rather than the product in general, but in my own personal opinion this is one flavour to avoid.

Finally I decided to test the tri-berry drink during a Yoga session and although the session wasn’t quite as intense as my other training sessions, the room itself was quite hot so I still found myself drinking a fair bit and thank-fully I found I enjoyed this flavour a lot and so it went down a treat.

In conclusion, this style of tab definitely makes what is usually quite a boring drink more enjoyable and the fact tabs are supplied in single-serving blister packets as well as tubes of 12 means a few can easily be carried in an energy gel pouch or pocket during marathons and half-marathons making them a great portable alternative from the usual choices of bottled water or super-sweet Lucozade/Powerade you’ll tend to encounter at most events. Yes some of the flavours aren’t for everyone but with a choice of 9 flavours and Nuun offering single-tube trial packs at £6 a pop this gives people a chance to try out a few to see which they enjoy and which they should avoid, and I know for sure I’ll be stocking up on their cherry limeade flavour and trying out a few more of their citrus flavours.
