Energy drink manufacturers have compared the amount of caffeine in their products to that of hot beverages sold in coffee houses, but the products are often packaged in very large sizes and they are not sold in controlled environments like coffee houses, which typically would not serve young children. Energy drinks are widely available in convenience stores next to traditional soft drinks, typically packaged in very similar cans and using similar marketing techniques.
Many of the products contain pharmaceutical grade caffeine and additional caffeine from other natural sources. This much caffeine in one serving can cause a person’s heart to beat rapidly, increase blood pressure, or other nervous, digestive or cardiovascular system side effects, health experts warn.
Some energy drinks in many of the popular lines, like Monster and Red Bull, can contain up to 400 mg of caffeine per can. In comparison, a cup of coffee typically has around 100 mg of caffeine.
Caffeine poisoning can occur in adults at levels higher than 400 mg a day; however children under 12 can experience caffeine poisoning at only 2.5 mg per 2.2 pounds of body weight.
A study published in September backed up the new findings, revealing energy drinks like Rock Star and Red Bull may cause serious heart problems.
French researchers revealed the popular energy drinks may be linked to increased risk of angina, irregular heartbeats and even sudden death.
