What sleep studies found near this dose

- Gardiner et al. 2023 (meta-analysis): To avoid losing sleep time, the authors suggest a coffee (107 mg per 250 ml) at least 8.8 hours before bed.
Estimate from a simple model: half-life of 3, 5 or 8 hours, 50 mg bedtime target. How we calculate
Caffeine by size
| Serving | Caffeine |
|---|---|
| 8 fl oz cup (248 g) | 81.8 mg |
| Small (372 g) | 122.8 mg |
How long does Caffè mocha stay in your system?
Our model halves caffeine every 5 hours for average metabolism, and every 3 or 8 hours for fast or slow metabolism. From one 8 fl oz cup (248 g) of Caffè mocha (82 mg), about 41 mg is still in your body 5 hours later and about 21 mg after 10 hours. If you clear caffeine slowly (an 8-hour half-life), about 34 mg is left after 10 hours.
Estimated caffeine left at 11:00 PM from one 8 fl oz cup (248 g) (82 mg), using a half-life of 5 hours for average metabolism and 3 to 8 hours for the range. How we calculate
| Had at | Left at bedtime (average) | Range |
|---|---|---|
| 8:00 AM (15 h before bed) | ≈ 10 mg | 3–22 mg |
| 12:00 PM (11 h before bed) | ≈ 18 mg | 6–32 mg |
| 3:00 PM (8 h before bed) | ≈ 27 mg | 13–41 mg |
| 6:00 PM (5 h before bed) | ≈ 41 mg | 26–53 mg |
How many fit in a day?
Reference amounts are for caffeine from all sources combined. Counted at the upper end of the stated amount, one serving at a time:
- Up to 400 mg a day for most healthy adults (FDA, EFSA): about 4 servings.
- Up to 200 mg at one time for healthy adults (EFSA): about 2 servings in one go.
- Up to 200 mg a day in pregnancy (EFSA, NHS): about 2 servings.
These are reference amounts for groups of people, not a personal limit. Some people feel jittery or sleep worse on much less. See the cutoff calculator for timing.
Good to know
USDA's value is a recipe estimate built from 60 g espresso, 305 g 2% milk and 37.5 g chocolate syrup.
How the serving amount was worked out: USDA lists 33 mg per 100 g; 248 g × 0.33 = 81.8 mg; 372 g × 0.33 = 122.8 mg.
Caffè mocha vs other espresso drink drinks
- Caffè latte: Caffè mocha has about the same amount of caffeine as caffè latte per 8 fl oz cup (248 g): 81.8 mg vs 86.4 mg.
