The Food and Drug Administration [FDA] has faced calls to investigate the PRIME Energy drink over the levels of caffeine in the canned beverage.

PRIME is a beverage brand launched by YouTubers Logan Paul and KSI and has become wildly popular.

It has become the must-have product for the younger generation, leading to stores selling out quickly.

However, the canned PRIME Energy drink, separate from the Prime Hydration drink that has no caffeine, is coming under scrutiny.

Sen. Charles Schumer has called on the FDA to investigate the drink, that has 200 milligrams per 12 ounces, equivalent to about half a dozen Coke cans or nearly two Red Bulls.

“One of the summer’s hottest status symbols for kids is not an outfit, or a toy—it’s a beverage,” said Schumer, a Democrat from New York. “But buyer and parents beware because it’s a serious health concern for the kids it so feverishly targets.”

A PRIME representative said the beverage comes with a warning label that says it is ‘not recommended for children under 18’ and that it has comparable lives of caffeine to rival brands.

“As a brand, our top priority is consumer safety, so we welcome discussions with the FDA or any other organisation regarding suggested industry changes they feel are necessary in order to protect consumers,” spokesperson Alyx Sealy, said in a statement.
