The exam support drink 'ZONe ENERGY [Solution]' has a refreshing sweetness and refreshing acidity that makes it easy to drink.



From the energy drink 'ZONe ENERGY', ' ZONe ENERGY [Solution] ', which focuses on exam support, will be released on Tuesday, January 13, 2026. It was developed with the theme of 'giving all examinees an invincible [solution]', and the actual product arrived at the GIGAZINE editorial department, so I actually tried drinking it to see what it tasted like.

The ZONe ENERGY [Solution] packaging features a blue design with the word [Solution] written in large letters. The top of the packaging reads 'Absolute Intelligence [AI],' which was inspired by the fact that many people use AI to find answers during exam season and study smartly.



The can has many mathematical formulas written in a spiral, including

the general term of the Fibonacci sequence , Ramanujan's formula for pi , Euler's gamma constant , and the binomial theorem . These formulas were supervised by Takumi Yobinori , a YouTuber who uploads lecture videos on mathematics and physics.



The ingredients are sugars (sugar (domestically produced), glucose), palatinose, caffeine, niacinamide, sweetener (sucralose), etc. Calories are 212 kcal per 400 ml bottle, and the caffeine content is 75 mg.



I was curious about what was inside, so I poured it into a clear glass.



It is a carbonated drink that is light blue in color.



When you drink it, the carbonation is mild, with a refreshing, artificial grape-like aroma, a clean sweetness, and a slight acidity. The aftertaste is refreshing, and the sweetness fades away quickly without lingering. The editorial staff who tried it commented, 'Unlike the chemical-like taste of so-called energy drinks, it's like a Ramune and is very easy to drink,' 'Rather than drinking it to start the engine, it feels like drinking it to calm down and continue working,' and 'After drinking it for a while, I felt a warmth deep inside my body. It was like stepping on the accelerator, and it may work more slowly than a typical energy drink.'



ZONe ENERGY [Solution] will be released on Tuesday, January 13, 2026. The suggested retail price is 223 yen.
