how much caffeine does red bull have
Red Bull's standard 8.4 fl oz (250 ml) can contains 80 mg of caffeine. This amount stays consistent across original, sugar-free, and most flavored varieties, scaling up proportionally for larger sizes.
Caffeine by Can Size
Red Bull offers cans in multiple sizes, with caffeine content calculated at roughly 9.5 mg per fl oz. Here's the breakdown from reliable sources:
| Can Size | Caffeine (mg) | Source Notes |
|---|---|---|
| 8.4 fl oz (250 ml) | 80 mg | Standard across all core varieties | [3][5][9][1]
| 12 fl oz (355 ml) | 114 mg | Sugarfree and Editions | [5][1]
| 16 fl oz (473 ml) | 151 mg | Regular energy drink | [7][1][5]
| 20 fl oz (591 ml) | 189 mg | Larger format | [1][5]
Compared to Coffee and Others
A standard Red Bull (80 mg) matches the caffeine in an average home-brewed coffee cup (about 80-95 mg per 8 oz). It's less than many competitors:
- Monster (16 oz): ~160 mg
- Bang Energy: ~300 mg
Coffee can vary widely (70-140 mg per cup), but Red Bull delivers a predictable hit alongside taurine, sugar (or not), and B-vitamins for that signature buzz.
Quick Health Context
At 80 mg, one can fits safely within the FDA's 400 mg daily limit for most adults—similar to coffee. Larger cans or multiples add up fast, so pace yourself, especially if sensitive. No major formula changes noted as of early 2026.
TL;DR: 80 mg in the classic 8.4 oz can; scales with size (~9.5 mg/oz). Like a cup of joe. Information gathered from public forums or data available on the internet and portrayed here.
