Facts & Fiction
Guarana contains a high amount of guaranine, a chemical
substance with the same characteristics as caffeine. This makes Guarana a stimulant
similar to coffee, which means that it:
- quickens perceptions
- delays sleep
- helps with endurance based activities
- can help to recover from a hangover
- impairs the appetite
- will lead to more frequent visits to the toilet
- causes a higher blood pressure and an increased heart rate
- can make you feel jittery and may prevent sleep at all.
Guarana is not:
- a 'miracle medicine'
- a dangerous drug
- an easy way to lose weight
- a vitamin
- a food supplement
Not proven by scientific research, but some users state that:
- Guarana is a 'Smart Drug'
- Guarana is an aphrodisiac
- their health improved thanks to guarana
- Theoretically, it is possible to overdose on caffeine or guarana. The fatal dose has
been estimated at 10 grams of pure caffeine / guaranine (taken at once!). Guarana seeds
contain maximal 10% caffeine, so when you would swallow at least 100 grams guarana seeds
at once, things start to look ugly. Our advice: don't even think about it.
To put all of this in perspective: the average cup of coffee contains 65-130 milligrams of
caffeine; some very strong guarana-based syrups can contain up to 350 milligrams.

- People with cardiac problems or a high blood pressure should avoid Guarana (and smoking
or drinking coffee, for that matter) When in doubt - consult your doctor.
- As with all stimulants, dependency may occur.
