In 2001, while living in the United States, I encountered energy drinks through the dance scene and was deeply impressed. After returning to Japan, I found that energy drinks were considered novelty beverages, so I established a comprehensive website in 2013 to share the true appeal of energy drinks. As an energy drink enthusiast, I began drinking them seriously again, collecting over 8,000 varieties of energy drinks from various countries. I am also active as a critic and expert, receiving media interviews.

Flavor of C4 ENERGY ORANGE SLICE

Upon opening, the scent of juice-free orange spreads immediately. Let's give it a try.
Flavor of C4 ENERGY ORANGE SLICE
When sipped, it revealed a mildly sweet, juice-free orange flavor. The acidity isn’t very strong either, making it a refreshingly clean-tasting drink ideal as a pre-workout beverage for C4 ENERGY’s typical training scenarios.

It feels like a simple juice-free orange drink, not a real orange with pulp, with the flavor adjusted to provide a smooth hydration experience.

There’s no chemical taste and no unpleasant artificial sweetness, allowing focus on training while enjoying the orange flavor.

Energy Ingredients of C4 ENERGY ORANGE SLICE

Contains 200 mg of caffeine, beta-alanine for fatigue reduction and endurance, citrulline for enhanced pumps, betaine for strength gains, and tyrosine as a precursor for adrenaline. Each ingredient is ideal for a pre-workout drink.

Beta-alanine, often included in pre-workout formulas or taken separately, can cause a tingling sensation on the face when consumed. This is a normal effect known as the beta-alanine rush, so there’s no need to worry.

Design of C4 ENERGY ORANGE SLICE

The design follows C4 ENERGY’s original line, combining the brand’s yellow with the flavor’s orange. C4 ENERGY is well known for its main yellow and black “danger” motif, which I really like. It’s a color scheme and design I enjoy a lot.

On the back, the ingredients from the C4 ENERGY series, “beta-alanine” and “betaine,” are listed.

For those who only drink energy drinks, these ingredients might seem meaningless, but for fitness enthusiasts who originally purchase C4 as a supplement, they are well known. This labeling clearly shows that the drink is branded for people involved in fitness.
