Statistics show that, in the UK, two thirds of children aged 10 to 17 and a quarter of children aged six to nine regularly consume energy drinks.
The ban, if approved, will apply to energy drinks containing more than 150mg of caffeine per litre.
"It's a question not of whether we do it, but how," a government source told the Guardian.
"There is no evidence that energy drinks have any nutritional value or place in the diet of children and young people. That's why we're pleased to see the government take action on this and other measures to tackle childhood obesity and improve children's health," Russell Viner, president of the Royal College of Paediatrics and Child Health, told the UK newspaper.
