Rockstar Energy (also branded as ROCKST☆R) is an energy drink that comes in over 20 flavors and is sold globally. Since its inception in 2001, Rockstar has become one of the top energy drink brands in the United States.

Rockstar Energy and Liver Damage

Rockstar contains a blend of B-vitamins like niacin (Vitamin B3). The problem is that niacin is toxic to the liver. It can elevate liver enzyme levels in the blood, which is a sign of liver injury. In high doses, niacin accumulates in the liver and causes inflammation. This side effect is also known as non-viral or toxic hepatitis. In severe cases, niacin overdoses cause severe liver injury, liver failure, or death.

Rockstar and Toxic Hepatitis

Toxic hepatitis is a side effect that causes inflammation in the liver. There are several reports of hepatitis in people who consumed a lot of energy drinks. One case was reported in a 50 year-old construction worker who drank 4-5 cans per day for 3 weeks (160-200mg niacin per day). Another case was in a 22 year-old female who drank 10 cans per day for 10 weeks (300mg of niacin per day).

Amount of Caffeine in Rockstar

The major ingredients in Rockstar Energy are caffeine, sugar, and water. It also contains a variety of herbs and supplements like taurine. There are two different levels of caffeine — 10-mg per ounce or 15-mg per ounce. The most highly-caffeinated Rockstar drinks contain 320-mg of caffeine in a 24-ounce can.

What is the problem?

Caffeine is toxic in high doses and many people do not realize how much caffeine is in the Rockstar Energy beverage they are consuming. This risk is especially serious for children and young adults, pregnant women, and people who have heart conditions (especially undiagnosed). Studies suggest that doses of caffeine above 500-mg are dangerous.

Rockstar Energy Heart Attack Lawsuit

A man who had a heart attack after drinking Rockstar Energy filed a lawsuit June 2015. The man, Oscar Maldonado, said he drank four cans of Rockstar in less than 8 hours. He developed chest pain and shortness of breath that gradually worsened. Three days later, he was hospitalized, diagnosed with a heart attack, and immediately underwent emergency surgery.

FDA Reports Injuries & Deaths

The FDA confirmed 18 deaths and over 150 injuries were associated with energy drinks from 2006-2012. Federal investigators warned that energy drinks were cited in over 13,000 emergency room visits in 2009.

In 2012, the FDA issued a report (PDF) on adverse events linked to the top three energy drinks, including Rockstar. Although no deaths were reported, 13 serious adverse events were linked to Rockstar since 2006. These events included:

  • Heart attack
  • High blood pressure

  • Abnormal heart rhythm
  • Mania and psychotic disorders
  • Flu-like illness
