How does caffeine work?
Caffeine acts on the central nervous system playing a role in alertness when tiredness occurs.
Is caffeine addictive?
Many people consume caffeine everyday as part of their diet and it can cause mild physical dependence. If you’re used to drinking two cups of coffee a day and you give it up, you may experience some mild withdrawal symptoms, such as a headache or fatigue, for a couple of days1.
How much caffeine can I have?
The maximum recommended caffeine intake per day is 400mg, from all sources.
