- Of the 10 other chocolate foods and drinks in our chocolate chart, 6 have more caffeine per serving, 3 have less, and 1 can have more or less, because its amount overlaps with this one's.
How much will be left at bedtime?
1 × 1 tablespoon (20 g) of Chocolate syrup
Left at 11:00 PM (8 h later), average metabolism
≈ 1.2 mg
Range 0.6–1.8 mg (fast to slow metabolism)
3.6 mg is already at or under the 50 mg this tool aims to have left at bedtime.
Estimate from a simple model: half-life of 3, 5 or 8 hours, 50 mg bedtime target. How we calculate
How long does Chocolate syrup 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 tablespoon (20 g) of Chocolate syrup (3.6 mg), about 1.8 mg is still in your body 5 hours later and about 0.9 mg after 10 hours. If you clear caffeine slowly (an 8-hour half-life), about 1.5 mg is left after 10 hours.
Estimated caffeine left at 11:00 PM from one 1 tablespoon (20 g) (3.6 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) | ≈ 0.5 mg | 0.1–1 mg |
| 12:00 PM (11 h before bed) | ≈ 0.8 mg | 0.3–1.4 mg |
| 3:00 PM (8 h before bed) | ≈ 1.2 mg | 0.6–1.8 mg |
| 6:00 PM (5 h before bed) | ≈ 1.8 mg | 1.1–2.3 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 111 servings.
- Up to 200 mg at one time for healthy adults (EFSA): about 55 servings in one go.
- Up to 200 mg a day in pregnancy (EFSA, NHS): about 55 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.

How the serving amount was worked out: USDA estimate (recipe value built from its Nestlé chocolate syrup record): 18 mg per 100 g; 20 g × 0.18 = 3.6 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.
