5-Hour Energy drinks are meant to give that boost of energy, but new reports suggest it could kill you.
The Food and Drug Administration is investigating reports of 13 deaths over the last four years in connection to the drink.
Since 2009, 5-Hour Energy has been mentioned in 90 filings with the FDA including serious conditions like heart attacks, convulsions and in one case spontaneous abortion.
The report is the second time in recent weeks citing energy drinks and deaths have emerged.
So far Living Essentials, which distributes 5-Hour Energy, has not responded to written questions about the filing.
