Red Bull vs Monster: the caffeine math
Label caffeine, size by size.
| Line | Size | Caffeine | ≈ coffees | % of 400mg/day |
|---|---|---|---|---|
| Red Bull 8.4oz | 8.4oz | 80mg | 0.8 | 20% |
| Red Bull 12oz | 12oz | 114mg | 1.2 | 28% |
| Red Bull 16oz | 16oz | 151mg | 1.6 | 38% |
| Monster Energy | 16oz | 160mg | 1.7 | 40% |
| Monster Ultra | 16oz | 140mg | 1.5 | 35% |
Per-can numbers hide the real difference: caffeine density. Red Bull's strongest line runs 9.4mg/oz vs Monster's 10.0mg/oz, and whichever you choose, the second can of the day matters more than the brand.
