Super Coffee has more caffeine than Coca-Cola Zero Sugar: 200mg vs 34mg in the same 12 oz bottle. That is a 166mg gap, and since the cans match, the per-serving number is the whole story.
These are different categories of drink, which changes how the caffeine arrives. Energy drinks and sodas list an exact number because caffeine is a measured additive; brewed drinks vary with the beans and the brew, so their figures are compiled averages. The numbers here are the standard published values for each.
Coca-Cola Zero Sugar vs Super Coffee: the numbers
| Coca-Cola Zero Sugar | Super Coffee | |
|---|---|---|
| Caffeine per serving | 34mg per 12 oz can | 200mg per 12 oz bottle |
| Caffeine per fl oz | 2.8mg | 16.7mg |
| Servings to reach 400mg (FDA context) | 11.8 | 2.0 |

The concentration gap is the striking part: Super Coffee packs roughly 6 times the caffeine per ounce. Sipping speed matters at that density; a 12 oz bottle finished in minutes hits differently than the same milligrams spread over a slow cup.
Which one should you pick?
Pick Coca-Cola Zero Sugar when you want the lighter dose or a slower ramp, and Super Coffee when you actually need the bigger hit and know your tolerance. If you are stacking either with other caffeinated drinks through the day, run the math against the 400mg reference rather than guessing.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
