People love it for its bold, sugary flavors and the immediate, tangible energy surge it provides, making it a staple in gaming, music, and late-night work culture.
⚠️ Watch-outs & how to enjoy it better
The high sugar content can lead to a sharp blood-sugar spike followed by a crash, and the caffeine may cause jitters or disrupt sleep. To counteract this, pair it with a protein-rich snack to slow sugar absorption, limit consumption to half a can, and avoid drinking it late in the day.
