"An Australian study found the sugar free version of the caffeine-loaded beverage causes the blood to become sticky and increases the chance of a life threatening clot.

Dr Scott Willoughby, who tested the drink on students, said: “One hour after they drank Red Bull, their blood systems were no longer normal. They were abnormal like we would expect in a patient with cardiovascular disease.

“If you add in other risk factors for cardiovascular disease - stress or high blood pressure - this could be potentially deadly.”

The study was carried out at the Cardiovascular Research Centre at the Royal Adelaide Hospital.

Red Bull spokeswoman Linda Rychter said the report would be assessed by the company’s head office in Austria."
