The FDA is reviewing concerns raised by Senate Majority Leader Chuck Schumer about the high caffeine content in Prime Energy, an energy drink founded by YouTube stars Logan Paul and KSI. Schumer claims the drink, which contains six times more caffeine than a standard can of Coca-Cola, is being marketed to children and teens. The company insists it complies with all FDA regulations and is not intended for anyone under 18. Canada's health agency has declared that Prime Energy should not be sold in the country due to its high caffeine content.
