How much will be left at bedtime?
1 × 1 tbsp (5.4 g) of Unsweetened cocoa powder
Left at 11:00 PM (8 h later), average metabolism
≈ 4 mg
Range 2–6 mg (fast to slow metabolism)
12 mg is already at or under the 50 mg this tool aims to have left at bedtime.
What sleep studies found near this dose
- Gardiner et al. 2025 (randomized trial): In 23 healthy young men, 100 mg taken 12, 8 or 4 hours before bed had no significant effect on measured or self-rated sleep.
- 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
How long does Unsweetened cocoa powder 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 1 tbsp (5.4 g) of Unsweetened cocoa powder (12 mg), about 6 mg is still in your body 5 hours later and about 3 mg after 10 hours. If you clear caffeine slowly (an 8-hour half-life), about 5 mg is left after 10 hours.
Estimated caffeine left at 11:00 PM from one 1 tbsp (5.4 g) (12 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) | ≈ 2 mg | 0–3 mg |
| 12:00 PM (11 h before bed) | ≈ 3 mg | 1–5 mg |
| 3:00 PM (8 h before bed) | ≈ 4 mg | 2–6 mg |
| 6:00 PM (5 h before bed) | ≈ 6 mg | 4–8 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 32 servings.
- Up to 200 mg at one time for healthy adults (EFSA): about 16 servings in one go.
- Up to 200 mg a day in pregnancy (EFSA, NHS): about 16 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 lists Dutch-process (alkalized) cocoa powder at 78 mg per 100 g, but each USDA cocoa value rests on a single sample.
How the serving amount was worked out: USDA lists 230 mg per 100 g (1 sample); 5.4 g × 2.30 = 12.4 mg.

General information, not medical advice
If you feel unwell after caffeine — for example chest pain, a fast or irregular heartbeat that does not settle, fainting, confusion or trouble breathing — get urgent medical help. If you are pregnant or breastfeeding, under 18, take medication, or have a heart, liver or anxiety condition, high blood pressure or a sleep disorder, ask a doctor or pharmacist what amount is right for you.
