To reduce potential harm, limit your intake to 16 ounces (473 ml) a day and avoid all other caffeinated beverages. Energy drink consumption has increased dramatically over the past two decades, especially among adolescents and young adults. Energy drinks are being aggressively marketed on the grounds that these products provide energy to improve physical and cognitive performance. However, studies supporting these claims are limited.
In fact, several adverse health effects have been linked to energy drinks; this has raised the question of whether these drinks are safe. This review was conducted to identify and discuss published articles that examined the beneficial and adverse health effects related to energy drinks. It is concluded that, while energy drinks may have beneficial effects on physical performance, these products also have potential harmful health consequences. The marketing of energy drinks should be limited or banned until independent research confirms their safety, especially among adolescents.
In each performance test, there were no significant changes to indicate that the energy drink had no effect on improving physical performance. Several studies have examined the behavioral effects of energy drinks that contain caffeine, glucose, taurine, and vitamins among their components. To safely drink energy drinks, limit yourself to 2 drinks a day, so you don't exceed the recommended caffeine intake. You should also avoid drinking energy drinks before or during an intense workout, as they can increase your heart rate and put extra pressure on your heart.
Energy drinks can have positive beneficial effects on physical performance in a variety of sports activities. At the same time, warnings about the dangers of energy drinks and stories of young people dying of heart failure after drinking too many energy drinks are becoming more frequent. However, just like coffee or tea, we know that taking too much of a dietary supplement can be bad, and that extends to energy drinks as well. Energy drinks have become very popular in recent years among people looking for “a pick-me-up” at noon, a pick-me-up in the morning, or even a way (not recommended) to delay the effects of drinking alcohol.
The results showed that energy drinks reduced both reaction times in behavioral control tasks and rates of mental fatigue, while increasing subjective rates of stimulation. They showed that the energy drink studied significantly improved aerobic endurance (staying at most between 65 and 75%). The truth is, when healthy people consume them in moderation and under the right circumstances, energy drinks are often safe. They found that eating energy drinks before exercise did not improve physical performance indices, which included the time elapsed until exhaustion, maximum oxygen consumption, blood pressure, heart rate, and capillary oxygen saturation.
The results revealed that both cognitive function and mood improved significantly in people with partial sleep deprivation who consumed energy drinks.
