Review: 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
Review: Great taste and good energy boost - I really like this energy drink. The Cherry Berry Lime flavor is refreshing and doesn't have that weird chemical aftertaste you get with some sugar-free drinks. I like that it uses natural caffeine and contains zero sugar.

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!!
