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 7,000 varieties of energy drinks from various countries. I am also active as a critic and expert, receiving media interviews.

Flavor of ROCKSTAR XDURANCE MARSHMALLOW

The sweet, rich, and creamy aroma wafts from the glass... At this point, I couldn't help but laugh. What have they created?

When you take a sip, the impression of the aroma is exactly the same: a smooth, creamy sweetness fills your mouth. You briefly feel the crispness of the carbonation, but for the most part, the mellow sweetness gently wraps around you, offering a soft, marshmallow-like atmosphere.

Whether it tastes exactly like marshmallows is subjective, but if you imagine the texture of a marshmallow in your mouth, it really starts to feel like marshmallow flavor. It's a strange thing!

I keep grinning every time I drink it, thinking, "How did they come up with this?" And I'm truly impressed by how they've managed to create such a sweet, rich flavor with zero sugar and zero calories.

The aftertaste lingers remarkably long on your tongue, yet there's no unpleasant artificial sweetener taste left behind. This is outstanding.

Both the taste and aroma are perfectly focused on achieving a soft, gentle sweetness, and though it shares a similar flavor profile with Rockstar XDURANCE's Cotton Candy, I personally prefer the smoother and more rounded marshmallow version.

Energy Ingredients of ROCKSTAR XDURANCE MARSHMALLOW

Contains 300mg of caffeine, 200mg of leucine, 50mg of isoleucine, 50mg of valine, and 4mg of CoQ10. The amount of BCAAs is negligible.

With 300mg of caffeine, it's great for keeping you awake or for pre-workout energy. Although, I can't quite imagine drinking something as sweet as marshmallow before exercising... (^_^;)

Design of ROCKSTAR XDURANCE MARSHMALLOW

This time, Rockstar XDURANCE goes with a pure white can, a contrast to the black base of previous XDURANCE cans.

The 300mg caffeine content is highlighted in red, making it stand out more than the other XDURANCE products.

Since they started highlighting the caffeine content prominently, the large "X" logo is now added to the side.

I'm not sure if this white and red combination is the best choice, though...

They could have gone all white, or maybe even made the letters of "XDURANCE" in pastel colors to match the marshmallow theme, which could have been interesting!
