C4 Performance Energy Drinks Cosmic Rainbow 500ml (12 pack) | Sugar Free Energy Drink with 160mg Caffeine, 250mg Betaine, 1050mg Taurine | Low Calorie Fizzy Drinks for On the Go Energy and Focus

C4 is a new brand to me, I just don't see it in the shops in the same way as I do more common brands of energy drink such as Red Bull, Monster, Reign and Rockstar - perhaps it is more common abroad/internationally. So despite being a regular drinker of energy drinks, this was my first time trying this brand. And I have to say that I'm very impresses. The taste is good - I tried "Cosmic Rainbow" and although its very sweet, the inclusion of malic acid means that it has a tartness to it aswell, a little like sour fizzy cola bottle sweets. The level of caffeine (160mg) gives a useful boost and is approximately the same as in other brands' 500ml drinks. I'm not sure that the taurine and betaine included have much scientific backing behind them in terms of efficacy. One thing I do like with the ingredients is that although the drink contains added B3 and B12 vitamins, these are at relatively sensible levels for supplementation - one can contains around 50% of the recommended daily amount of each - I'd rather that it had none since vitamin mega-dosing can be dangerous, but the amount here is relatively low, certainly compared to brands I've come across such as Monster (500%) and Moose (4000%) which seems irresponsible from those brands and would even be illegal in some European countries! All in all, I think this is going to be my go-to energy drink for now and I'll look forward to trying some more flavours on those days when I fancy a caffeine hit from a refreshing cold drink rather than a hot coffee.

Great value and very long date Also Great taste

Great value if you can get it on offer. I tend to aim for around £1 per can. Taste good and doesnt give any of the "tingles" you might get with pre wourkout. The cosmic rainbow flavour smells like skittles but the taste isn't that strong. Would still recommend, they do taste good. Google described the taste as similar to skittles, i wouldn't agree.

Taste Nice

I drink a fair amount of C4 before workouts because I love the beta-alanine tingle, and it always wakes me up without a massive crash later. I usually stick to the Frozen Bombsicle or Skittles flavors, but I decided to give Cosmic Rainbow a shot for a change of pace. It is definitely still very tasty—it’s sweet and fruity, kind of like a handful of melted candy. However, it’s just not quite as nice as the other options they have. It feels a little generic compared to their branded collabs. I’d happily drink it again if it was the only cold one in the fridge, but it probably won't be my first choice next time.

Tastes great, like a fist full of skittles. Sweet but not overpowering and 26cals a can, great if you're watching the sugar intake and gives a good buzz with 160mg of caffeine.

Good price. Not keen on taste

Amazing

Amazing! The best tasting sugar free energy drink in my opinion

Some of the cans arrived half-empty, and one of them leaked onto the table.

I am not joking. Is this good or bad? Up to you to decide. The similarity to skittles pops in every now and then but its not the first thing that comes to mind

Allt jag vill ha i en PWO ! synd bara så svårt att hitta i Sverige och dessutom lite grann för dyrt. Men.. smaken( särskilt när drick är kallt) energi som den ge- överstiger alla mina förväntningar!
