Best Beta-Alanine Energy Drinks of 2025

"I find C4 Sugar-Free Watermelon fits perfectly into my workout routine. I take it 30 minutes before training, and honestly, it's the best pre-workout ever! The taste is amazing and it delivers incredible results during my workouts, reducing muscle fatigue and keeping me energized."

"These drinks are so good! They taste fantastic and give me just the energy boost I need."

"I absolutely love the C4 Jolly Rancher flavor! It’s spot on and works great for my workouts or whenever I need a little pick-me-up."

"I've been searching for an energy drink that really works, and C4 Energy is it! It provides me with a consistent boost, whether I'm working out or just need a pick-me-up during the day. The blend of 200mg caffeine and performance ingredients really makes a difference, and I love that it comes with zero sugar and low calories."

"I decided to try the C4 Performance Energy Drink in Starburst Strawberry, and I was pleasantly surprised! The flavor is refreshingly sweet, and it truly captures that classic strawberry taste without any unpleasant aftertaste. The energy boost was immediate, giving me a clean, focused energy that helped me power through my workout without the jitters."

"As someone who has replaced coffee with C4, I can say that the sweet flavor is appealing, and I don’t experience any jitters. However, I do find it a bit pricey compared to other options. Still, it’s a nice treat for an energy drink!"

"I've used pre-workouts for years, and as I've aged, many make my heart race or spike my blood pressure. This uncarbonated C4 provides great energy and strength without those issues. Great stuff!"

"I enjoy a boost before hitting the gym, and C4 is one of the best options. The Orange Slice flavor is decent, but the Fruit Punch is my favorite. I appreciate the energy and effectiveness, but caffeine sensitivity should be considered."

"The taste is quite good, with a hint of artificial watermelon, which I don’t mind. I find that C4 gives me a quick surge to power through my workouts. Personally, I prefer the Orange Slice flavor, as it tastes a bit more natural and isn't overly sweet like the Fruit Punch."

"I absolutely love these drinks! They give me a nice pick-me-up without any jitters or anxiety. The caffeine from green tea provides a lasting boost that helps me through my workday."

"I use this for a boost during school hours due to my ADHD. The taste surprised me; it wasn't overly sweet and was really refreshing. The energy lasted for hours without any blood sugar spikes or jitters."

"Overall, I found the taste decent and the 200mg caffeine gave me a noticeable energy boost. However, I think the price is a bit high unless I catch them on sale."

"At this stage in my life, I can't just wake up and have all kinds of energy. I was searching for something to complement the caffeine pill I take before hitting the gym. I always felt tired around 2 or 3 PM. After discovering this drink and reading the reviews, I decided to give it a try. I opened a can on a Saturday at around 10 AM and was pleasantly surprised. It provided a smooth energy ramp-up without any jitters. I felt energized and focused throughout most of the day. I definitely recommend it and will be incorporating it into my routine about 3 to 4 days a week."

"The taste is fantastic, and the energy boost is like nothing I've experienced with other energy drinks. I was skeptical at first, but after nine subscriptions, I can confidently say I'm convinced. I found a flavor I love and won't be looking back. Give it a try, and you won't regret it!"

"I've been using this product during college and in the military. Yes, it might be a bit much, but it delivers exactly what you need. I prefer it over Monster, thanks to its high caffeine content of 350 MG and 41,000% B12 daily value. I enjoy the taste, which has a tart flavor that some say resembles grape."

"I've found my new favorite energy drink! The OG Luck flavor is just right—not too sweet and no unpleasant aftertaste. With 200mg of caffeine and added ingredients like maca and ginseng, I get a nice energy boost without feeling jittery or crashing later. It's a great, healthier option that’s definitely worth trying!"

"I was impressed with the zero-sugar energy drink. It delivers a smooth energy boost without any crash, and the taste is surprisingly good for a sugar-free drink. The flavors are refreshing and not overly sweet, making it a clean choice for anyone looking to maintain their diet."

"While I appreciate the great flavors and low calories, the sourness of some flavors isn't my favorite. However, aside from that, the overall taste is enjoyable, and I think they offer good value for money with their decent energy boost."

"I absolutely love the energy this drink provides! It really wakes up my mind and body. The premixed formula works better for me than their other products, and the taste is pretty good. I do experience a bit of itchiness in my palms, but I enjoy that sensation. I only need to drink a quarter of a bottle each day, which is perfect since I prefer not to consume a lot of liquid, especially energy drinks, to feel the effects."

"As someone who's not into pre-workout powders, I found this drink to be a fantastic alternative. I've finished one case already and I can't wait for the next! It gives me the energy I need to power through my workouts, plus I really enjoy the taste. The fact that it isn't carbonated is an extra bonus for me."

"I really enjoy the taste of this drink, and it definitely gives me a pick-me-up every time. The screw cap and the non-carbonated feature are fantastic. However, I wish it came in 16 ounces instead of just 12. Otherwise, it's a great product!"

"This product gives me the energy boost I expect from an energy drink, though the flavor is a bit sharper than other orange drinks I've tried."

"I find the flavor almost too good, reminiscent of orange crush soda, and it effectively works as an energy drink."

"Having tried numerous energy drinks during my night shifts, I can confidently say that Spike wakes me up and provides more energy than any other brand I've experienced."

"I don’t usually like energy drinks, but these have no weird aftertaste. The blue raspberry flavor is noticeable. It’s a bit thicker than water, so I might enjoy it more if I mix it into a shake. At $46.74 for 12, it’s a good deal. I received this through Vine and am leaving this review voluntarily."

"I ordered this thinking I would get 12 individual shakes, but I only got one shake and couldn’t return it. It’s disappointing."

"My brother, who is really into pre-workout drinks, absolutely loves this! He thinks it tastes great and provides a solid energy boost. The blue raspberry flavor isn’t overpowering, which is a plus."
