NOTE: we do NOT recommend added caffeine for anyone.
The information below has been left here for historic purposes.
Tea (both black and green, with the former containing more caffeine) is the most recommended source of caffeine.
Drinking coffee is not recommended, because in this case the amount of caffeine is much higher – it may be particularly dangerous with brain cancers.
Also, coffee, unlike tea, acidifies the organism.
