Senate Majority Leader Chuck Schumer has asked the Food and Drug Administration to investigate Prime Hydration for its marketing towards children and the high amounts of caffeine in its energy drinks.

Prime Hydration was founded by social media influencers Logan Paul and KSI. The company has signed sponsorships with soccer teams FC Barcelona and Arsenal, MLB’s Los Angeles Dodgers, and UFC as Prime’s retail sales reached $250 million in its first year.

A 12-ounce can of Prime’s energy drink contains 200 milligrams of caffeine, significantly more than the caffeine found in a 12-ounce Coca-Cola (34 milligrams) and an 8.4-ounce Red Bull (80 milligrams). In a press release, Schumer called Prime a “status symbol for kids” and “a serious health concern for the kids it so feverishly targets.”
