Many supermarkets and other major retailers in Britain already decline to sell energy drinks to children. But they remain readily available from smaller stores and vending machines, and some brands are sold for as little as a pound, about $1.30.

The government said that one 250-milliliter can of energy drink often contained around 80 milligrams of caffeine — the equivalent of a cup of coffee or nearly three cans of cola — and up to 60 percent more sugar on average than regular soft drinks. It said excessive consumption among children had been linked to headaches, sleep problems, stomach aches and hyperactivity.

The plan would ban the sale to children of energy drinks that contain more than 150 milligrams of caffeine per liter.
