Explainer
In plain language
Added caffeine is caffeine put into a product on purpose, separate from what naturally occurs in coffee, tea, or cocoa. It is a stimulant that increases alertness and reduces the feeling of tiredness. In food and drinks it usually appears as purified anhydrous caffeine or as an extract like green coffee extract, and it shows up in energy drinks, sodas, and some snacks and supplements.
Assessment
Why it is flagged
Caffeine is well studied and considered safe for most healthy adults in moderate amounts, which is why this flag is low severity. The FDA advises that healthy adults limit intake to about 400 mg per day, roughly four to five cups of coffee, and notes that very high single doses, especially from pure powdered caffeine, have been associated with serious effects. Clear Label flags added caffeine mainly for visibility: caffeine-sensitive people, pregnant consumers who are often advised to limit intake, and parents watching children's intake benefit from knowing when it has been added rather than naturally present. Effects like jitteriness, disrupted sleep, or a racing heart vary a lot from person to person. Tracking which products contain added caffeine against your own energy and sleep is exactly the kind of pattern Clear Label helps you see.

Practical
Reading the label
Look for caffeine, anhydrous caffeine, or green coffee extract in the ingredient list. Total caffeine amounts are not always listed, and it can hide inside proprietary energy blends where the exact dose is not broken out.
Alternatives
If you want to avoid it
Some people choose decaffeinated versions or naturally lower-caffeine options like herbal teas when they want to cut back. Checking labels for caffeine-free variants of the same drink is often the simplest comparison.
FAQ
Common questions
How much caffeine is too much?
The FDA advises healthy adults to stay under about 400 mg per day, though sensitivity varies. Pregnant people are often advised to consume less, and pure powdered caffeine can reach dangerous amounts in tiny volumes.
Is added caffeine different from coffee's caffeine?
Chemically the caffeine is the same. The label distinction matters because added caffeine can appear in products you might not expect to be stimulating, like snacks or flavored water.
Why does caffeine affect me more than other people?
People metabolize caffeine at different speeds, partly for genetic reasons, so the same dose can feel very different. Logging caffeinated products against your sleep and energy is a practical way to find your own threshold.
