Red Bull is an energy drink produced in Austria. Its founder and chairman is Dietrich Mateschitz who is politically conservative. According to a 2005 study, it was the most popular energy drink in the world, possessing over 60% of the market share. Its main alertness-inducing ingredients are caffeine, taurine and glucuronolactone, all of which can cause adverse cardiovascular effects. However, a study by the European Food Safety Authority (EFSA) has concluded that the amounts present in Red Bull are considered safe.
Red Bull also owns several sports teams, most notably Red Bull New York (Major League Soccer), RB Leipzig (Bundesliga), Red Bull Racing (Formula 1), and Red Bull 5G (which is an eSports [i.e. Video Game tournament] event).
