According to researchers from Mayo Clinic, healthy young adults who do not consume caffeine regularly may be susceptible to cardiac events on using energy drinks. The study goes to cement earlier concerns about the risks associated with the consumption of energy drinks on offer. Lack of caffeine in the body has been found to result in a rise in resting blood pressure, which can be triggered by an intake of an energy drink.


The study was carried out on 25 healthy individuals, all between the age of 19 and 40, focusing on heart rate and blood pressure changes after consumption of one of the many commercially available energy drinks or a placebo drink.

The blood pressure and heart rate were also recorded 30 minutes before consumption of an energy drink/ placebo and then compared with those of people who did consume caffeine and those who did not.

Researchers were able to detect an increase in blood pressure on people who used an energy drink as opposed to a placebo drink. The rise was even more prominent in people who did not consume caffeine on a regular basis. Blood pressure levels more than doubled in caffeine naïve adults after consumption of the energy drink.

The findings of the study are to be presented at the American college of cardiology. Energy drink consumption has been on the rise especially among young people who occasionally don’t engage in physical activities to stay fit.

The effects of the energy drink to the heart rate were found to be more evident in older people who in one way or another might have a higher risk to these side effects. Researchers also affirm that people with existing medical conditions might experience a higher increase in blood pressure after consuming an energy drink.

However, researchers stress the need to consume energy drinks in moderation and taking into consideration the many health risks at hand.

    Energy drinks have been safely consumed for nearly three decades around the world, and in the U.S. for about 15 years. Despite misinformation often in the media, most mainstream varieties have about half the caffeine as a similar size cup of coffeehouse coffee. That said, in addition to complying with all FDA regulations, energy drink makers take several voluntary steps to
    safeguard consumers. For instance, product packaging features a statement that makes clear energy drinks are not intended (or recommended) for children, pregnant or nursing women, and persons sensitive to caffeine. This, among other actions, is a clear indication that the industry is doing its part to ensure these products are marketed to the audiences for whom they are intended.
