Less sugar, More energy
I tried this C4 Smart Energy because I needed something that gives me energy without making me feel jittery. The first thing I liked is that it has zero sugar, so you don’t get that crash afterward and it’s not just an energy drink it also helps with focus, which makes it perfect if you work from home or need to concentrate. The Cherry Berry Lime flavor is really good, it doesn’t taste artificial like others. I’ve been using it in the mornings or whenever I need a quick boost during the day and honestly, you can feel the difference. I recommend

Wife Loved em!
Personally I’m not a berry fruit kinda dude but the missus loved this so much we ran through the 12pk within the week.No sugar, no colors, no fake flavors. 200mg of caffeine that comes from green coffee bean extract so it’s natural. I noticed it has Cognizin Citicoline and for those interested - this is a patented citicoline supplement that helps with memory, focus and mental energy. Definitely better than whatever the big name energy drink brands stuff into their cans.Price wise this is solid to buy off Amazon! It came in at half the price of buying a single can of Red Bull from a gas station and it came straight to my doorstep undented and not shaken up!

Good energy boost without the sugar crash
I’ve tried a lot of energy drinks and this one was surprisingly good. The flavor is refreshing and not overly sweet, especially for a sugar-free drink. It gives a nice steady energy boost without making me feel jittery or causing a crash later. I also like that it feels lighter compared to some heavier energy drinks. Great option for busy days, workouts, or when you just need extra focus and motivation.

Lime and it’s surprisingly refreshing! 🍒🍋
The flavor is fruity with a nice lime kick, not too sweet, and I love that it has zero sugar. It gives a smooth energy boost and helps me stay focused without feeling jittery. Perfect for busy days or a quick pick-me-up! ⚡️

A staple.
We love these drinks. The caffeine content is too high because of the smaller size. The natural caffeine reduces jitters. This is our favorite flavor. The case is enough to last a few weeks without having to buy individually at the store for significantly more money.

Fit and feeling fantastic!!
C4. Smart energy is actually extremely amazing and not only do I feel more energized, but I feel more hydrated while working out. I absolutely love the cherry berry lime. It smells incredible!! doesn’t remind me of some weird fruity gasoline like other energy drinks!! the ingredients are fantastic the green coffee beans I think really makes a difference and it sets it apart from other energy drinks!! this is a great value of the 24 pack literally last me almost a month if not longer if I’m drinking one a day or one every other day !! This is awesome for if you’re at the gym or going for a walk or just during the day and you need a little pick me up!!
