Solid boost, no jittery effects!
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.

Best Energy Drinks I’ve Tried—Perfect for Workouts and Long Days
I’ve tried a lot of energy drinks over the years, but Cellucor C4 Performance and C4 Smart Energy are easily the best I’ve come across.C4 Performance Energy Drink is my go-to pre-workout. It gives me a clean, intense boost that actually feels like it’s doing something without the crash or jitters. I feel more focused, more driven, and I can push harder in the gym. The BetaPower really makes a difference—I can feel it in my endurance and strength, especially during heavy lifts or cardio. And the flavors? Seriously good. Frozen Bombsicle is my favorite—it tastes like nostalgia and motivation in a can.Then there’s C4 Smart Energy, which is a total lifesaver on my work days. I’m a nurse doing night shifts, so staying mentally sharp is non-negotiable. Smart Energy gives me that focus and clarity I need without making me feel wired. It’s smooth, tastes great, and I love that it’s zero sugar and packed with brain-boosting ingredients like Cognizin.These two drinks have completely replaced coffee and most other energy drinks for me. Whether I need physical power or mental focus, C4 has something that works—and I actually look forward to drinking them.

My New Go-To Energy Boost!
As someone who leads an active lifestyle, finding a pre-workout drink that aligns with my health goals can be a challenge. That’s why I was thrilled to discover the C4 Energy & Smart Energy Drinks Variety Pack. Let me tell you, these drinks have become my go-to fuel for all my workouts!The variety pack comes with four delicious flavors, making it perfect for those who like to switch things up. From the refreshing Strawberry Watermelon Ice to the invigorating Sparkling Peach Mango, each flavor packs a punch and leaves me feeling energized and focused for my workouts.One of the things I love most about these energy drinks is their versatility. Not only do they provide a much-needed energy boost before my workouts, but they also serve as a great coffee substitute or alternative. On those early mornings when I need a pick-me-up, I can reach for one of these drinks instead of a cup of coffee, and I still get the energy I need without the jitters or crash later on.The fact that these drinks are sugar-free is a huge plus for me. I appreciate that I can enjoy the taste without worrying about consuming unnecessary calories or compromising my health goals. The absence of artificial colors or dyes is another great feature, as it gives me peace of mind knowing that I’m putting only quality ingredients into my body.The 12-pack variety pack is not only convenient but also a great value for money. I can easily grab a can whenever I need a quick energy boost, whether it’s during a workout or a busy day at work.Overall, I highly recommend the C4 Energy & Smart Energy Drinks Variety Pack to anyone looking for a reliable and healthy way to stay energized throughout the day. With its variety of flavors, zero calories, and no artificial colors or dyes, this pack is a winner in my book. Give it a try and experience the difference for yourself!

Good Energy Drink
Only giving 4 starts because the flavors of the black cherry and watermelon burst weren’t very good, but that could be personal preference. The Cherry Berry Lime and Blue Raspberry were amazing! Gave me just enough energy to not make me jittery. If I order again I would get the flavors that I like.

Great energy and flavor
I always purchase the Cherry berry lime as it is my favorite. I work long hours and tend to have an energy drink on shift most nights. Others I’ve tried severely dehydrated me and make me have to pee a lot whereas these C4 Smart Energy do not have the same effect. The caffeine in these are derived from green coffee beans rather than asynthetic caffeine source so it gives a pleasant pick-me-up without jitters and no crash later. These are the only energy drinks I consume now. I just feel better than when drinking other brands.

New Fave
Definitely worth the money. I love the taste and health benefits of this C4 flavor. It gives me a ton of energy without feeling jittery at all. I didn’t have any issues with leakage or smell. Easy to use, love the watermelon colors.

Taste good. No bad aftertaste
Like the taste. 👅 Clear in color. Gives me the right amount of energy.Only issue was the expiration date was within a few months. So I will not buy from this seller again.

I was taking this for several weeks now to try to improve my focus for studying, and it was doing the total opposite. Whenever i drink this I can’t focus or even grasp the most basic concept. It also screwed up my memory and gave me lots of severe headaches and sleep problems.It also tastes horrible compared to diet coke or other diet drinks.

Noticeable improvement in energy level and focus on the C4 Smart Energy version. Bought this for working on a critical project, had it in the morning after breakfast. I was able to avoid mental and physical fatigue and keep working for 10+ hours straight, with full on energy, focus and motivation, without needing any breaks/coffee/tea in between. Remember you can have only one per day and I believe its not recommended to use this continuously for more than 8 weeks. I intend to use this only when I have something critical to get done. Taste is very good (Peach Mango / Smart Energy)
