If you’re constantly on the go and looking for a low sugar energy drink that actually delivers a real boost without the dreaded crash, let me introduce you to your new obsession: Nutrein Clean Energy. I got my hands on some cans of the stuff recently and have been putting it to the test to see how it matches up to my usual energy drinks. Spoiler alert, it kind of blows them out of the water!
Before we dive in though we’ve got a little treat for you – you can get 15% off your order of Nutrein Clean Energy when you use the code GYMFLUENCER at the online checkout.
Nutrein Low Sugar Energy Drink
Nutrein’s low sugar energy drink is a grown-up upgrade from the energy drinks you used to grab to see you through an all-nighter or to pick you up after a big night out. In fact, it’s one that’s actually kind of good for you. Each can contains 80mg of natural caffeine (from green coffee beans, so no weird chemicals) and a stack of extras your brain and body will thank you for.
We’re talking 7 essential vitamins, including B vitamins to tackle tiredness, plus 5 nootropics like L-Theanine for focus, Ashwagandha for calm, and Maca Root to give your mood a boost.
The flavours
Can we just take a second for the flavours? Because Nutrein seriously nailed it. I tried all three and here’s the verdict:
- Peach Passion – This one is sofruity and fresh. The peach and passionfruit combo is juicy, a bit tangy, and is ideal for mid-morning slumps.
- Mango Sunrise – If you like tropical vibes, this is your can. Mango meets blood orange, and it somehow tastes like sunshine in a tin. I took this one pre-workout and felt like I could take on the world.
- Pink Lemonade – Honestly, this one surprised me the most. It’s sweet but not sickly, with a lovely berry twist. Perfect for those mid-afternoon slumps.
All three are super refreshing, lightly sparkling (not aggressive bubbles, we love that), and don’t leave that weird aftertaste you get with some low sugar energy drinks.

No crash, no jitters, just clean energy
Now this was the big test. I’ve tried plenty of low sugar energy drinks that promise no crash, but the post-caffeine nosedive still always gets me. But that’s not the case with Nutrein.
That 80mg of natural caffeine gives you a smooth, steady lift which is enough to wake you up, focus your brain, and power through a workout or work meeting. But it doesn’t leave you twitchy, sweaty, or wide awake at 3am regretting everything. I had one before an evening workout and was still able to wind down for bed like a functioning adult. Honestly, it’s the kind of boost that works with your day, not against it.
Another win for Nutrein? The size. These 250ml cans are the perfect grab-and-go option. I tossed one in my gym bag, one in my work tote, and kept one in the fridge for emergency brain fog days.
They’re also ideal if you’re trying to avoid the sugary vending machine trap or want something to sip instead of your third iced coffee of the day.
And price-wise? A 4-pack is just £5.99, and a 12-pack is £16.99. Honestly, not bad at all considering the ingredients, benefits, and the fact that it actually works.
