The sale of energy drinks could be banned in England to anybody under 18, amid fears they are damaging children's health, the prime minister has said.
The government has launched a public consultation on its plans to make it illegal to sell the drinks to children.
Energy drinks contain high levels of sugar and caffeine and have been linked to obesity and other health issues.
The government is asking for views on what age the ban should apply to, but gave under 16 and under 18 as options.
Scotland, Northern Ireland and Wales have the power to implement their own bans.
UK youngsters are among the highest consumers of energy drinks in Europe, research has previously suggested.
The drinks contain high levels of caffeine and sugar, often much more than those of standard soft drinks.
Excessive consumption has been linked to a range of health issues in children, from obesity, tooth decay, headaches and sleep problems to stomach aches and hyperactivity.
The ban would apply to drinks containing 150mg of caffeine or more per litre. Many shops already have their own voluntary bans in place for under-16s, but it is still possible for children to buy the drinks from some retailers and vending machines.
"It is vital that we do all we can to make sure children have the best start in life and I encourage everyone to put forward their views, " said Prime Minister Theresa May.
