Caffeine has long become a staple on film sets – crews working long hours may get very irascible if the coffee  runs out or worse the coffee you provide is not up to scratch.

This is especially true in New Zealand and Australia where coffee culture has bloomed since the development of the flat white in Melbourne in 1993. Tastes have quickly migrated from perked or instant coffee to strong expresso served with warm milk, foam, chocolate or black. caffeine is also not only in coffee you can find caffeine in tea cocoa and energy drinks.

Caffeine is a naturally occurring stimulant found in tea, coffee, cocoa and cola as well as some other plant based foods such as Guarana. Foods containing caffeine have been used for medicinal purposes for thousands of years. Caffeine is one of the most commonly consumed stimulants in the world. It is absorbed easily and rapidly by both the stomach and small intestine, it then circulates throughout the whole body, including the brain. Thats why that first coffee always creates a stimulating jolt and is often reffered to as a “hit”.

Caffeine affects the central nervous system and are generally associated with mood effects, such as feelings of increased energy, efficiency, self-confidence, alertness, motivation and concentration.

So how much should you have?

There are currently no recognised safety limits for caffeine . Whilst research supports that a caffeine intake of up to 400 mg/day is not associated with an adverse effects in healthy adults, 3mg per kilogram weight is the level generally accepted as the recommended limit of caffeine intake for adults.
