How Much Caffeine Is in Coca‑Cola Zero Sugar?
Caffeine levels in Coca‑Cola Zero Sugar are relatively low compared to coffee or energy drinks. A standard 12 fl oz can contains 34 mg of caffeine, which is less than half the caffeine in a typical cup of coffee.
- 12 fl oz can: 34 mg caffeine
- Per fl oz: ~2.8 mg caffeine
- Daily Limit (Adults): 400 mg recommended maximum
This makes Coca‑Cola Zero Sugar a mild stimulant, suitable for those who want a gentle lift without the intensity of stronger caffeinated beverages.

Coca‑Cola Zero Sugar Caffeine by Can Size
Coca‑Cola Zero Sugar is packaged in multiple can sizes, each offering the same caffeine concentration but different total amounts depending on volume.
- 7.5 fl oz mini can: ~21 mg caffeine
- 12 fl oz standard can: 34 mg caffeine
- 16 fl oz tall can: ~45 mg caffeine
Smaller cans are ideal for portion control, while larger cans provide a slightly stronger boost. Regardless of size, the caffeine concentration per ounce remains consistent.
Coca‑Cola Zero Sugar Caffeine in Bottles
Bottled Coca‑Cola Zero Sugar offers larger serving sizes compared to cans, making it a popular choice for sharing or extended consumption. The caffeine concentration remains consistent across all formats, but the total caffeine content increases with volume.
- 20 fl oz bottle: ~57 mg caffeine
- 1 liter bottle: ~95 mg caffeine
- 2 liter bottle: ~190 mg caffeine
These larger formats are often shared or consumed gradually, so caffeine intake depends on serving size rather than the total bottle content.
Serving Size Breakdown: Caffeine per Ounce and Milliliter
Coca‑Cola Zero Sugar maintains a consistent caffeine concentration across all packaging formats, which makes it easy to calculate intake regardless of whether you’re drinking from a can, bottle, or pouring into a glass.
- Per ounce: ~2.8 mg caffeine
- Per 100 ml: ~9.5 mg caffeine
This breakdown helps consumers track intake when pouring into cups or mixing with other beverages.
