Caffeine in chocolate, pills and pre-workout
The sources people forget to count: a bar of dark chocolate, a tablet, a scoop before the gym. Two of these are the largest single doses on the whole site.
| Drink | Serving | Caffeine | Time to clear | Latest for an 11 pm bedtime |
|---|---|---|---|---|
| Pre-workout | one scoop | 201 mg | 13 and a half hours | 9:32 am |
| Caffeine pill | one 200 mg tablet | 200 mg | 13 and a half hours | 9:34 am |
| Dark chocolate | 1.7 oz bar (50 g) | 40 mg | already clear | any time |
| Milk chocolate | 1.7 oz bar (50 g) | 10 mg | already clear | any time |
Caffeine pills and pre-workout powders are measured, not brewed, so they hit the same 200 mg every time with no variation. That precision cuts both ways: it is easy to dose deliberately, and easy to take one at 5 pm without thinking of it as a drink. Chocolate is minor by comparison, though a 100 g bar of dark chocolate matches an espresso.
