You might expect the caffeine content of a drink to be right there on the label. Usually it isn't — and that surprises people, given how much caffeine varies between drinks.
What's required
For most foods and drinks, listing the exact caffeine amount is voluntary, not required. If caffeine is added to a product, it must appear in the ingredient list, but the milligram amount doesn't have to be stated. Many energy drinks and some sodas now disclose it voluntarily, and dietary supplements with caffeine have their own rules — but your morning latte generally won't tell you.
How much is safe
The FDA cites 400 milligrams per day as an amount not generally associated with negative effects for healthy adults — roughly four or five cups of coffee. Sensitivity varies widely: some people feel jittery at 100 mg, and pregnant people are usually advised to stay under 200 mg. Caffeine has no % Daily Value because it's not an essential nutrient.
How much is in common drinks
- Brewed coffee (8 oz): ~80–100 mg
- Espresso shot: ~60–75 mg
- Cold brew (16 oz): ~200 mg or more
- Black tea (8 oz): ~40–50 mg
- Cola (12 oz): ~30–40 mg
- Energy drink (16 oz): ~150–160 mg, sometimes far more
Why BevFacts shows it anyway
Because caffeine is one of the two numbers people most want from a drink (the other being sugar), the BevFacts label puts a caffeine line on every label and shows it as a percentage of the 400 mg daily guidance — even though real labels aren't required to. Add espresso shots and you'll watch it climb.
