The rumor: It’s possible to get caffeine poisoning
As he was driving down an Ohio freeway minutes after swallowing five Magnum 357 caffeine pills, Christian Brenner started to vibrate — and the cars in his rearview mirror did as well. Fortunately, Brenner pulled over and walked around in an effort to try and come down.

Caffeine acts as a stimulant in humans. It can be found in the seeds, leaves and fruit of plants like coffee or kola nuts.
“Safe doses of caffeine are usually quoted at around 200 to 300 milligrams, or two to four cups of coffee per day,” says Dr. David Seres, associate professor of clinical medicine at Columbia University.
