Monster Rehab Energy Drink Class Action Lawsuit

By Kimberly Mirando


Monster Rehab energy drinkMonster Energy Co. has been hit with a class action lawsuit claiming that its Monster Rehab Green Tea + Energy drink contains unknown amounts of epigallocatechin-3-gallate (ECGC), “an extremely dangerous and potentially lethal ingredient,” and that the company fails to warn consumers that it could cause hepatoxic side effects, or chemical-driven liver damage.

California resident and lead plaintiff Jennifer Wooding alleges in the Monster Rehab class action lawsuit that medical research shows ECGC has been linked to liver injuries and could cause adverse side effects, and that it should not be consumed with alcohol or by those with compromised livers. Yet advertisements for Monster Rehab suggest it should be consumed as a pick-me-up after a long night of partying. 

“Instead of being the safe energy drink that Defendants promised, the subject product causes dangerous hepatotoxic side effects, including without limitation, death, acute liver failure, hepatitis and other liver injuries,” the Monster Rehab class action lawsuit says. “Despite knowing that the subject product could result in severe injury and even death in susceptible users, Defendants marketed and sold the subject product to millions of unsuspecting consumers without any warning whatsoever.”

While ECGC has antioxidant properties in small doses, the class action lawsuit points to 20-year-old research that shows ECGC has toxic liver effects “when used in the doses present in dietary supplements.”

Monster Rehab Green Tea + Energy contains an unknown amount of ECGC, which has been linked to numerous cases of liver injury in Europe, the class action lawsuit says.

It is the latest development in a series of legal filings against the popular energy drink company.

The FDA is investigating five deaths and one non-fatal heart attack in connection with Monster Energy drinks that occurred over the past year. The family of one of these victims, a 14-year-old girl who died of a toxic caffeine overdose, has filed a wrongful death lawsuit against Monster over their daughter’s death. The company has also been hit with a class action securities fraud lawsuit filed by investors accusing Monster of failing to disclose it is being investigated for alleged false advertising and marketing by a state Attorney General.

Other energy drink makers are also facing litigation over allegedly dangerous amounts of caffeine in their products. The makers of Four Loko are still fighting a class action lawsuit alleging the now-banned alcoholic energy drink “causes sickness and alcohol poisoning, and even death.” And an October 2012 class action lawsuit claims VPX Redline energy drink causes extreme adverse health effects that resemble a cocaine overdose.

The Monster energy drink class action lawsuit is seeking to represent a proposed class of all consumers nationwide that purchased Monster Rehab Tea + Energy. It is seeking restitution, punitive and treble damages, a corrective advertising campaign and more for alleged violations of the Consumers Legal Remedies Act and California Business and Professions Code, breach of express and implied warranties, and unjust enrichment.

The Monster Rehab Class Action Lawsuit case is Wooding v. Monster Energy Company, et al., Case No. 30-2012-00609716-CU-BT-CXC, California Superior Court, Orange County.

    I suppose side effects like headaches after drinking monster energy drinks it might be a good idea not to continue. You can get a headache from just about anything with caffine the law suit has to do with liver issues from ECGC. And a child that consumes any large amounts of caffeine can be lethal. What do u do about that? Can’t prohibit kids from buying anything with caffine in it. It all comes down to parent responsibility. Sorry to hear that happen thou, no child should have to die from that.

    • Anon April 3, 2014

      Half of these people are idiots. If you have headaches don’t drink the freaking drink. It’s not monsters fault their daughter died, sorry to say she was stupid and probably drank way too many.

  • Patrick December 17, 2014

    Why not just have them release the actual per serving/can amount of ECGC so that we, as a society of conscious & informed consumers, can decide if it needs to be either banned (if found to contain too much ECGC) or merely used with discretion?

    • Brandon December 30, 2015

      because they cant actually tell its the tea leaves that are used to make the drink no way to do it unless every can was checked and recorded on the can which would be a pain.. really sad to see it go why cant they just put a caution or something of the sort. I mean why has this not been an issue with ANY tea ? I am not sure.

    Why is a 14 year old girl drinking anything other than smoothies, milk, and water? Her parents are to blame for not bestowing healthy habits on her. America is so stupid. It is so cheap to eat healthy. People just don’t want to take the 2 hours plus to prep there food for the week. Quit looking for quick fixes. That little girl should of been eating a huge breakfast, not drinking caffeinated drinks with supplements her parents probably cannot even pronounce. People going to start suing alcohol companies for cancer and other related effects even though they are not alcoholics?

    I used to drink the monster green tea a lot ..I was loosing wait but then one day I drank it and got a numb filling and like a rush filling in my fingers and I new it was from drinking the monster green tea drink so to test myself I stop drinking It for awhile like a month then just to try it again it did the same filling so I stopped but now I still have trouble sometimes I think it messed me up from drinking it to much..

  • jacqueline September 13, 2015

    How do you get information on the lawsuit. My husband drank these daily.

  • Soulless1388 February 19, 2016

    LMFAO wow I have massive health problems and it is a known fact that drinking to much or anything is bad. Green tea in large amounts isn’t good for anyone at all anyways. But others shouldn’t have to be affected for a few that have either abused the Monster Product or some kinda freak thing. And it is known that energy drinks and liquor don’t mix but because of the high people are gonna mix them. I really wish 5his world was heading in a different way but it’s not. People just want a quick buck these days and working for it is so out of the question.

  • Soulless1388 February 19, 2016

    Oh and when I was in the Marine Corps. most of us drink these (all Monster Products) all the time close to if not an actual overdose on a daily basis and if we are in a combat zone we drink worse. So really why would the public do this.
