The group, which has 15 stores in Jersey, announced the move this week in line with their UK counterparts.
Anyone wishing to buy products containing over 150 mg of caffeine per litre will now need to show ID if asked to do so by a sales assistant.
Mark Cox, chief operating officer for the Co-op, said that the decision was taken following growing concern about the consumption of energy drinks among young people.
‘After consultation with UK Co-op Group, we recognise that we must act.
‘It is a balance between offering choice and doing the right thing, so the decision was taken to play a role in limiting young people’s access to high-caffeine drinks.’
The drinks are said to have a serious impact on children’s behaviour, with one teaching union describing them as ‘readily available legal highs’.
The group is the latest company with stores in the Island to introduce the measures, along with Waitrose and Boots.
And in the UK, Asda, Aldi, Lidl, Morrisons, Tesco and Sainsbury’s have also all implemented a ban.
