The US Food and Drug Administration (FDA) has said it will address concerns surrounding the Prime Energy drink, while health officials in Canada have decided to recall the product because it exceeds legal caffeine limits.
Prime Energy was created by YouTube stars KSI and Logan Paul and has caused a social media stir, with some resellers claiming to sell a single bottle for up to £100.
US senate majority leader Chuck Schumer raised concerns in an open letter to FDA commissioner Dr Robert Califf, which highlighted that the drink has six times more caffeine than a standard 340ml Coca-Cola can.
While a spokesperson for Prime said the drink is not intended for anyone under 18, Schumer argues that it is marketed towards a social media demographic, and that its founders also attract a younger fanbase.
The Prime spokesperson noted that the drink “complied with all FDA guidelines before hitting the market”, CNBC reported.
Adults can consume up to 400mg of caffeine a day without negative health effects, according to the FDA, and while there is no set limit for children, doctors say children under 12 should not consume any caffeine.
Prime drinks contain 200mg of caffeine.
“Consumers should take care when consuming for the first time a new packaged food containing added caffeine if the amount of caffeine in the food is not declared on the label,” said the FDA.
Prime Energy has not yet been officially launched in Canada, but some stores are selling it without approval, BBC News reported.
In Canada, the upper limit for caffeine is 180mg per serving.
The Canadian Food Inspection Agency said officials are "actively working to address this issue" of stores possibly selling Prime Energy without approval, according to the BBC.
