A recent news story has noted the consequences of drinking popular energy drink Red Bull in excess as a UK driver was booked for dangerous driving after drinking 20 cans (20 cans!) of the product.
Interestingly, the Canadian Journal of Psychiatry published a case report in 2001 suggesting that excessive intake triggered a manic episode in a gentleman with bipolar disorder.
Red Bull has had several papers published on it in scientific journals. It is often not referred to by brand, but often by the euphamism of ‘energy drink [with taurine and caffeine]’ or ‘functional energy drink’.
Despite the marketing hype, it has been genuinely shown to improve mental performance for a short duration, and particularly usefully, to counteract dangerous driver sleepiness during tests with a driving simulator.
…when taken in sensible doses, of course.
