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.

Excellent Energy Drink with Great Taste and No Crash
Pros: great taste, energy without a crash, no dyesCons: how healthy really are energy drinks?I was looking for a "healthy" energy drink that I could use to replace my water enhancer and didn't have any dyes. This one fit the bill. Its on the pricier side compared to other options but its not the most expensive one out there. It works without the crash typical of energy drinks. They're carbonated and similar to Sprite in terms of texture. I can't comment on caffeine sensitivity since the only time I was sensitive to caffeine was after I had my son and I initially started drinking caffeine again. Overall, I like these enough to subscribe and save so I'll always have some on hand. As a mom who is the primary parent and works full time with a career, I can't live without some form of caffeine.

Clean Energy with Great Taste
I've tried numerous energy drinks, but C4 Smart Energy Drink – Boost Focus and Energy with Zero Sugar, Natural Energy, and Nootropics - 200mg Caffeine - Cherry Berry Lime (12oz Pack of 12) stands out. The Cherry Berry Lime flavor is refreshing without being overly sweet. It provides a solid energy boost without the jitters or crash. The zero sugar and natural caffeine are definite pluses. Highly recommend for anyone needing a reliable pick-me-up.

Not my favorite but still great!
Taste great but makes me jittery! Price is comparable to most. Strong carbonation but that’s expected. Lower sugar content which I like. Variety of flavors so you don’t get burnt out on them.

Great flavor and super caffeine kick!!
Really great taste and superb caffeine kick! Tastes more like a real watermelon flavor vs a candied watermelon like the vast majority of the other watermelon energy drinks on the market. 200mg of caffeine is great to have when you need a jolt to make it through the day. I would absolutely recommend this drink to anyone who wants a more "true" watermelon flavor. Another great perk of these energy drinks are the ingredients that specifically help improve focus and help mental clarity! The carbonation level is kinda high but it's not terrible. The effectiveness of these can't be denied!

My favorite energy drink
I love these drinks. No negative effects from the caffine and I do feel like they sharpen my focus while I study. The flavor is also my favorite of all energy drinks I've tried. I wish they were a smidge cheaper as they're usually a few dollars more than Red Bull but they're still worth it to me.
