Review: Nuun active hydrations tablets

nuun hyrdation tabs review

First I will say what the nuun website says about their product,

portable nuun hydration tabs allow athletes, outdoor enthusiasts and other active folks to easily and conveniently manage hydration, whenever and wherever they need it

nuun is light and refreshing with no sugar and is non-sticky so it’s great in bottles and hydration packs

nuun is just electrolytes – it is not a source of sugar or carbs, which allows adventurers to independently manage energy needs with their favourite choice, be it bars, gels, bananas or brownies. (after all, on a hot day, you need to replace more fluids and electrolytes than on a cold day, but you don’t need all the extra sugar and carbs.)

nuun solves hydration so you can enjoy the day

over the past 10 years, nuun has built a passionate following among cyclists, runners, triathletes, swimmers and outdoor enthusiasts. the world’s top elite athletes, (for whom staying hydrated is critical for performance), as well as recreational athletes and active folks alike, use nuun

nuun comes in variety of flavours so try them all and find out which are just right for you


nuun hydration tablets

Why nuun?

I've heard others raving about nuun on twitter (@lcdunn) so just before Amsterdam marathon I sent a tweet to Nuun asking if they would be nice enough to send me a sample so I could try before I buy. To my surprise, they did - unlike a couple of other brands who didn't even acknowledge my cheeky tweet.

The postman delivered the parcel and instantly I was curious, it was bigger than I had expect. When I opened it I found 3 tubes of different flavoured tabs and a nice nuun water bottle to use when making up the drink. 

What are electrolites?

Simply put, electorolytes are salts and minerals found in the blood which help your body function. A good reference for more information I found was RunnectConnect


The tabs come in a very robust plastic tube. Nicely sized to allow me to throw them in to my kit bag and not need to worry about getting them damaged, but not so small that I can't find them when I want them.

How do they taste?

Really nice actually. I thought they might taste a bit powdery due to the bicarbonate soda which is used to make them desolve. They give a nice refreshing taste to the water and don't leave any stickiness in your mouth, like some gels do. 

Would I buy them?

I've tried the lemon+lime, tri-berry and orange and they are all really easy to drink. 

Drop one tablet in to 16oz (450ml) of water, give it a minute or two to disolve and bingo! A nice tasting drink. 

Since the tablets arrived, the weather hasn't really been hot enough to try them out as intended but I have found myself drinking them at my desk at work. They quinch my thirst really well. I enjoy drinking plain water but I find I visit the loo less often if the water is mixed with a Nuun tablet - not sure if there is a scientific reason for this, maybe the body absorbs more of the liquid than plain water?

I really like the size of the tubes that the tablets come in. Small enough to carry with me where ever I go but big enough that I don't need to buy a new tube that often. There are 12 tabs inside each tube, giving me 5 litres of flavoured water! Plenty!

A tube costs approx £3.99 which is a really good price when you think about how much water you get from it. 
As I mentioned the the tube itself is very robust. I can throw a tube in to my kit bag and not have to worry about smashing the tabs in to tiny bits. I imagine this will also come in handy if going abroad or just travelling. I can pack a tube or two in to my luggage and know it will make it in one piece! I would imagine they could be taken on a plane in hand luggage as well. 

I've drank a bottle of nuun water before training to see how my stomach reacts to it and all was good. I've found in the past, some sports drinks leave a nasty taste in my mouth or actually make me more thirsty, I didn't find this with the nuun tabs. They aren't fizzy so sit in my stomach well and I will be making sure I have a bottle mixed ready to go when it starts to get warmer again for our track training. 

Having a mixture of flavours was great because, although I like all the flavours I was supplied with, it's nice to mix it up a bit. I wouldn't say I have a favourite out of them but I'm keen to try the other flavours on offer. Kona Cola is on my list as the first I want to give a go.

Would I recommend them?

Yes, as I said, they taste nice, easy to transport and I can see myself just carrying a tablet or two in my pocket, maybe wrapped in some clingfilm or a plastic pocket during longer runs in the summer along with a £1 coin. I can then pop in to a shop, buy a bottle of water and mix it on the go.
