Manufacturer statements · Source by source

Caffeine, as stated.

Caffeine amounts stated on manufacturer pages, alongside the original serving wording and source evidence.

Percentages compare one stated product amount with the FDA's 400 mg/day figure for healthy adults. They are arithmetic comparisons, not consumption targets, and do not apply to people who are pregnant or breastfeeding, children, teens, or people with heart conditions or caffeine-interacting medications. Serving wording and product notes qualify the stated amounts; a missing serving size is not inferred. Read the FDA context →
