While coffee has been the energy-boosting beverage of choice since the 16th century, a new pick-me-up has been gaining popularity since the late 1990s: the energy drink. The colorful, loud cans fill gas station coolers everywhere, just waiting to be grabbed by everyone from tired truck drivers to high schoolers mid-cram session who are looking for a quick kick of energy and focus.
Though they might be effective pick-me-ups in the moment, most of these drinks contain a large amount of caffeine, sugar, additives, guarana, taurine and L-carnitine that can potentially have lasting health effects, according to the Center for Disease Control and Prevention. Potential risks include increase in blood pressure and heart rate, dehydration, irregular heartbeat, heart failure, anxiety and insomnia. The risk is especially high for children and adolescents.
A single 8-ounce energy drink can have as much as 250 milligrams of caffeine, according to the FDA. In comparison, one 8-ounce cup of coffee will usually contain up to 100 milligrams. Additionally, many energy drink brands will offer 16- and 24-ounce cans containing multiple servings.
The American Heart Association recommends that men consume no more than 36 grams of added sugar per day. For women, it recommends a limit of 25 grams of added sugar per day. That means a single day’s allotment could be maxed out on just one energy drink — or even half of an energy drink, depending on which brand you choose.
As for the other ingredients, there are a few things you should know. Guarana is derived from seeds of an Amazon plant that contain approximately four times the amount of caffeine found in coffee beans, and according to research published in the journal PLOS One, also contains other compounds thought to enhance caffeine’s stimulant effect. Ingredients such as taurine and L-carnitine sound scary but are really just amino acids thought to help the body metabolize energy. According to a study published in the journal Regulatory Toxicology and Pharmacology, they are safe to consume even in large amounts. Alternatively, additives made of salt compounds (which usually either include the suffix “chloride” or begin with the word “sodium”) can increase the sodium levels in each can; a high-sodium diet could increase the risk of high blood pressure and other health complications.
Here is a closer look at what’s inside some of the most popular energy drinks on the market.
