Cellucor C4 Smart Energy Drink - Sugar Free Performance Fuel & Nootropic Brain Booster, Coffee Substitute or Alternative | Cherry Berry Lime 12 Oz - 12 Pack

C4 Smart Energy is a functional energy drink that delivers a solid boost without the jittery side effects common in high-caffeine beverages. It contains 200mg of caffeine from natural sources and includes ingredients like Cognizin® Citicoline, which is marketed to support mental focus. The drink is sugar-free and low in calories, which makes it a good option for people watching their diet or trying to avoid crashes from sugar-loaded drinks. The flavor is surprisingly clean and not overly sweet, with options like Peach Mango, Frozen Bombsicle, and Cherry Limeade. It doesn’t have the harsh aftertaste some energy drinks do. I noticed a noticeable increase in alertness and focus about 20 minutes after drinking it, which lasted a few hours. Overall, C4 Smart Energy is a solid choice for students, gamers, or professionals who need a mental boost without the downsides of sugary or overly aggressive energy drinks.

This is the best energy drink that I’ve ever had. No alkaline taste like Red Bull, and doesn’t ever feel like my heart is going to pop out of my chest. It’s light and tasty and works great.

Great flavor and value for the money.

Unlike the Cherry Limeade, these are pretty good! They aren’t the best out there, but I would probably buy them again if there was a good sale.

C4 Smart Energy Drink has easily become one of my favorite energy drinks. What really sets it apart is how clean and balanced the energy feels. It provides a noticeable boost in focus and alertness without the jitters, racing heart, or hard crash that comes with many other energy drinks. The taste is excellent—smooth, refreshing, and not overly sweet or artificial. It goes down easy whether I’m drinking it before a workout, during a long workday, or when I need extra mental focus. The inclusion of ingredients geared toward brain function really shows, especially when I need sustained concentration. I also appreciate that it doesn’t leave me feeling wired or drained afterward. The energy feels controlled and steady, making it great for both physical activity and everyday use. Overall, C4 Smart Energy delivers exactly what it promises: clean energy, great flavor, and reliable performance. I would highly recommend it to anyone looking for a smarter alternative to traditional energy drinks.

Tastes great.

It’s tasty. One can, I leisurely sipped while wearing a Hawaiian shirt and lounging outside in the sun. one can, I was in a hurry and had to chug. Both went down smooth.

Love the flavor. Just the right size. I've tried others but this flavor the best so far.
