How Much Caffeine Should I Have in a Day?
What is Caffeine?
Caffeine is a stimulant naturally found in the leaves and fruits of some plants. It’s naturally found in products such as coffee, black and green tea, and cocoa. It’s also added to cola soft drinks and energy drinks. It may also be in chocolate bars, energy bars and some non-prescription medications, such as cough syrup. Guarana is also a natural source of caffeine, which you may find added to some energy drinks1.
Caffeine is a stimulant, which means it (temporarily) increases activity in your brain and nervous system. It also increases the circulation of chemicals such as cortisol and adrenaline in the body.

We can now buy a variety of non-alcoholic gin and beer that make a great cocktail alternative. It's very much the same with coffee, as modern decaf coffees are a great way to avoid too much caffeine.
While you may not want to give up that all important cup of caffeinated liquid gold in the morning, decaf coffee can be perfect for the afternoons; you’ll still get all the wonderful coffee flavour with a fraction of the caffeine.
Personally, I drink our regular cold drip coffee in the mornings but come the afternoon it’s decaf all the way. An afternoon decaf coffee, lime and soda is a longstanding fav.
