People have gone into cardiac arrest after consuming more than one energy beverage, and when they’ve done sort of further analysis on these individuals, they haven’t been able to find anything abnormal other than the very high levels of caffeine and taurine in the toxicology. In one case, a young 28-year-old who drunk eight cans of an energy drink actually went into cardiac arrest, and they found arteries of his heart were completely locked up. When they were able to open them up, all the testing revealed nothing wrong with this person other than he had high levels of caffeine and taurine.
Common Ingredients of Energy Drinks
Most energy drinks typically contain following ingredients:-
- Large amounts of caffeine
- Added sugars
- vitamins, such as B vitamins
- Legal stimulants, such as guarana, a plant that grows in the Amazon; taurine, an amino acid that’s naturally found in meat and fish; and L-carnitine, a substance in our bodies that helps turn fat into energy.
Effects of Energy Drinks on Our Health
The impacts that energy drinks may have on your heart and cardiovascular system could be due to how the caffeine interacts with other ingredients, such as the taurine, Taurine, a common amino acid, can affect the levels of water and minerals in your blood. Bits of guarana, the plant from the Amazon, are commonly added to energy drinks and already contain caffeine, which can increase a drink’s total caffeine amount.
The blood vessels in the heart during exercise have to get larger; they dilate and get larger so that more blood flow can get to the heart. The possible interaction of caffeine with the other ingredients in energy drinks may impact the function of your arteries by inhibiting them from dilating properly, especially during exercise.
How Many Energy Drinks are Safe
Depending on how many energy drinks you consume, doses of caffeine equal to or above 200 milligrams can be linked to caffeine intoxication. Symptoms include anxiety, insomnia, gastrointestinal irritation, muscle twitching, restlessness and periods of inexhaustibility. The Consortium for Health and Military Performance recommends that service members, from sailors to Marines, limit their caffeine intake to no more than 200 milligrams every four hours and no more than 800 milligrams throughout the day.
For adolescents, 12 to 18, the academy recommends that they should not exceed 100 milligrams of caffeine a day, an intake of caffeine greater than 100 milligrams a day has been associated with elevated blood pressure in adolescents. As for most adults, up to 400 milligrams of caffeine a day appears to be safe. Healthy adults who choose to drink energy drinks should not exceed one can per day.
