nuun Review – from my running club

I’m a big fan of nuun hydration tablets and the company in general. I go through a lot of their hydration tablets over the summer and after my long runs in general. You add one tablet to around 500ml of water and let it fizzle and then drink.

It’s become a bit of a habit for me after my long run to fill a big drinks bottle up with water and throw in a hydration tab and then cart that thing round with me for the rest of the day. I’ve even taken it shopping and to friend’s BBQs – my family and friends are used to it. If the weekend is especially hot I’ll have one the day before a long run and then one after.

I love the flavours and I like that the water I’m guzzling (I guzzle a lot) isn’t just washing me out of my necessary electrolytes.

The guys at nuun graciously supplied me with a number of single samples of two flavours of nuun to give out to my running club (Hedge End Running Club) for them to try and then feed back their thoughts.


The two flavours were: Strawberry Lemonade and Lemon Lime. The tablets contain no sugar or carbs and have almost zero calories. I cannot stand Lucozade or Powerade or any of the other sugary sports drinks but sometimes it is nice to have some flavour to your water and to get the benefits that some of the sports drink provide, i.e. the electrolytes to keep your body in balance when you sweat, and I find nuun is a great win-win choice.


So I was happy to give out samples to members of my running club to see what their thoughts were. [On a side note, this was a somewhat logistical nightmare. I put out a message on our club’s Facebook page and was inundated by requests to try them. Then became the nightmare of trying to get these bad boys out to the people who wanted them. I don’t go to every training session and not everyone goes to my usual Netley parkrun so it was quite tricky (not to mention not knowing what people looked like if I’d never met them before!). But anyway, I hope everyone who wanted to try them tried them. Though not everyone gave me a review back…*sighs* ;-)]

Here are a collection of some of the responses people gave after trying the tablets. Brought to you from Hedge End Running Club (though I haven’t used their last names for privacy):

Peter: “Personally I found them a bit ‘bland’ compared to the SiS ones I am used to but then some people might prefer that.
They also say to dilute them in 450ml rather than 500ml which is a bit annoying when most water bottles are 500ml or have a 500ml marker. Means you also cant pop them in a bottle with a sports cap on it from a shop as they are mainly 500ml if that sort of thing bothers you 🙂 50ml probably makes little difference but shows the American heritage rather than European I guess.”

Karen: “I also agree – compared to Zero tabs I would say these were too weak. I prefer a bit more flavour. I don’t think the product is something that you would notice making a huge difference brand to brand, so for that reason I would stick with zero for the better flavour.”

Mark M.: “I’ll fill my pockets, Anna. I found them easy to drink. On 4+ hour cycle rides other brands become a bit sickly to drink, I found these ones much easier on the taste buds.”

Kate: “Like the flavours. Like that they have vitamin C and B2 in them. (However…they could be mistaken for condoms packet in the individual packets!!!!).”


Terry: “The one’s I had were quite refreshing but the flavours were a bit weak and needed to be a bit stronger.”

Chris: “Have to agree with Terry, the flavours could definitely have been stronger. I mixed each tablet with a pint of water, whether that was the wrong ratio I can’t say. That said it didn’t particularly make me want to drink more fluids as a rehydration aid and from a few tablets it’s difficult to say whether it helps your body absorb more fluid. Will more than likely get some more to try over a longer period 🙂 Verdict: undecided (& probably not well informed enough about the product yet).”

Carlo responded to Chris’ comment above: “Pint of water way too much, Chris. I got a 500ml bottle, took a sip out of it and added the tablet. Tasted ok to me, but I’ve no idea if any of this stuff works at all for me.”…Later informed me after completing a ridiculously hard Dorset Invader Marathon: “I took 2 half litre bottles with me yesterday and just dropped a tablet in when I fancied it. Not sure if it helped in any way, but tasted alright.” (He did an amazing job at the marathon!)

Julie: “I preferred the strawberry lemonade flavour I think. I actually like the more subtle flavours. They seemed to do the job for me but I’m not one of the top end racing types!” Julie has done over 30 marathons so judge for yourself on whether she’s a top end racer 😉

Mark S.: “I’m not sure about them – I’m taking them during day at work to keep hydrated post cycling in. All that seems to happen is I need the toilet about 20 minutes after drinking.
The one’s I had were quite refreshing but the flavours were a bit weak and needed to be a bit stronger.”

Conclusion: I think people enjoyed them and liked the benefits they gave them, but some found the flavours a bit weak. I must admit I do somewhat agree but sometimes I add a bit of squash and I’m happy as Larry. I agree with Mark M. though that you don’t always want an overwhelming flavour when you’re out racing for a long time (especially if it’s warm) as it can be a bit too much, so subtle flavours help with that respect.

And I agree with Kate – hilariously it did look like I was handing out Durexes to my fellow club members 😉 And my dad, when he saw the box of them on my dining table, said awkwardly  “er, what exactly are these, Anna? And why do you have so many?”. But this is the same with other hydration tablet samples too, not just nuun! 😉

Have you tried nuun before?

Do you enjoy sugar-based sports drinks and find they help? I used gels instead to get my carbs and energy during a marathon.

How do you stay hydrated when it’s warm?

**Full Disclosure: I was sent a free box of samples from nuun to give out to my running club in exchange for their opinions and an honest review. I haven’t altered what they said in their reviews (other than one or two typos – I can’t help myself!) All opinions were included, none were left out that I’m aware.**

  1. I’ve never tried nuun but I use sis electrolyte tabs after my long runs. Sometimes after long runs I get really dehydrated and my fingers swell up and I feel all funny and kind of hungover – I’ve since learnt the importance of hydrating pre and post run. The sis ones are more of a convenience thing really because they sell them in tesco. I got some high 5 ones as a sample once but I didn’t like those as much because the flavours were too weak and funny tasting. Sometimes I find they taste a bit off and ‘salty’, but when I REALLY need one, I don’t notice the taste at all haha. Love the idea of getting your running club all involved too!

  2. How great that nuun sent you tablets for your running club to try. I’ve not tried either the lemon lime or the strawberry lemonade flavours before but absolutely adore nuun after getting sent a selection of flavoured tubs to review last year. I now wouldn’t go into a long distance race without a tube of the lemonade flavour. I’ve yet to try the watermelon ones but as I used up another tube of tablets at the Grim 70m this weekend I think now is the perfect time to stock up! 🙂
    I like that they have a weaker flavour than some products. Because I use them for long distance, like a couple of your clubmates have mentioned it makes them much easier to stomach over long periods of time. You don’t want anything too flavourful or sickly sweet.
    It did make me laugh that it looked like you were dealing condoms at club!
    I would also not have been able to help myself at editing the typos! Haha!

  3. I love nuun tabs! I like the hint of flavour as I generally drink water. I got some free zero or high five tabs at a race recently and they were so strong it was off putting. Also the additive s were not good and you could only have two per day. Before a race I have nuun instead of water and after hot runs I will too. I just wish the flavours were easier to find as wiggle seem to be stopping the tropical ones.
