85% of the US population consumes at least one caffeinated beverage per day, mean intake among consumers is 165mg per day, and the FDA cites 400mg a day as an amount generally not associated with dangerous effects in healthy adults. Every number on this page is linked to a primary or reputable compiled source; anything we could not verify was cut.
TL;DR: the five headline caffeine statistics for 2026
- 85% of the US population has at least one caffeinated beverage per day (Mitchell et al. 2014, Food and Chemical Toxicology).
- Mean daily caffeine intake among all ages: 165mg; highest in ages 50 to 64 at 226mg per day (same study).
- FDA benchmark: 400mg a day, about two to three 12-ounce cups of coffee (FDA).
- EFSA: single doses up to 200mg and habitual intake up to 400mg per day do not raise safety concerns for healthy adults; 200mg per day for pregnant women (EFSA).
- US convenience-store energy drink sales passed $16 billion in 2025, up 10% (Circana via C-Store Dive).
Caffeine content by beverage category
The FDA's consumer guidance lists caffeine per 12 fluid ounces by category; EFSA lists typical single servings. Both are compiled reference values, and brewed drinks vary with the beans and the brew.
| Beverage | Caffeine | Source |
|---|---|---|
| Brewed coffee, 12 oz | 113 to 247mg | FDA |
| Decaf coffee, 8 oz | 2 to 15mg | FDA |
| Black tea, 12 oz | 71mg | FDA |
| Green tea, 12 oz | 37mg | FDA |
| Caffeinated soft drink, 12 oz | 23 to 83mg | FDA |
| Energy drink, 12 oz | 41 to 246mg | FDA |
| Espresso, 60 ml single serving | 80mg | EFSA |
| Filter coffee, 200 ml cup | 90mg | EFSA |

How much caffeine Americans actually consume
The most-cited nationally representative intake study is Mitchell et al. 2014 in Food and Chemical Toxicology (abstract), based on a 7-day beverage diary of 37,602 consumers. Its findings: 85% of the US population consumes at least one caffeinated beverage per day; mean daily intake from all beverages was 165mg for all ages combined; intake was highest among consumers aged 50 to 64 at 226mg per day; and coffee was the primary contributor to caffeine intake in all age groups. These are consumption figures, not health findings.
Coffee remains the delivery vehicle: 66% of American adults drank coffee in the past day, averaging nearly 3 cups per day among drinkers (NCA National Coffee Data Trends, Sept 2025).
The guidance numbers everyone cites
The FDA cites 400mg a day, which it describes as about two to three 12-fluid-ounce cups of coffee, as an amount not generally associated with dangerous negative effects for healthy adults. The European Food Safety Authority reached the same 400mg daily figure (about 5.7mg per kg of body weight), adds that single doses up to 200mg do not raise safety concerns for healthy adults, and sets 200mg per day for pregnant women. Tolerance varies by person; treat these as reference points, not advice.
The energy drink category
Energy drinks are the fastest-moving caffeinated category at retail: US convenience-store dollar sales grew 10% in the year ending December 31, 2025 to more than $16 billion, with unit sales up 8%, per Circana data reported by C-Store Dive. Category-level detail, including per-brand caffeine, is on our energy drink statistics page.
