Caffeine is a central nervous system stimulant, which is often used to help restore mental alertness when drowsiness occurs.
Caffeine is a stimulant and it can cause a mild physical dependence, but most experts don’t consider it to be addictive. 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 days.1
It takes your body 3-5 hours to eliminate half of the caffeine you ingest. The remaining caffeine can stay in your system for up to 14 hours.2
The maximum recommended caffeine intake per day is 400mg, which is 8x PRO PLUS tablets.
The amount of caffeine in a cup of tea or coffee depends on how enthusiastic you are with the teaspoons, but you can use this table as a guide:
|Filter coffee||100 ml||50 - 100 mg||£0.27 (approx.)|
