Energy drinks are defined as soft drinks that are high in caffeine (over 150mg/litre). Over half of energy drinks products in 2015 & 2017 were also high in sugar. Parents and teachers support a ban on sales of energy drinks to children, linked to physical symptoms and adverse effects on behaviour. In 2018 all major UK supermarkets as well as the members of the Federation of Independent Retailers in Scotland introduced a voluntary ban on sales of energy drinks to under-16s, thus acknowledging that these products are potentially harmful to children.
