An energy drink is a type of non-alcoholic psychoactive functional beverage containing stimulant compounds, usually caffeine (at a higher concentration than ordinary soda pop) and taurine, which is marketed as reducing tiredness and improving performance and concentration (marketed as "energy", but distinct from food energy). They may or may not be Soft drink and may also contain sugar, other sweeteners, or herbal extracts, among numerous other possible ingredients. Energy drinks are different from sugar-sweetened beverages. While both energy drinks and sugar-sweetened beverages typically contain high levels of sugar, energy drinks include stimulants like caffeine and taurine and are marketed for energy, and sugar-sweetened beverages like sodas and fruit juices usually do not.
They are a subset of the larger group of energy products, which includes bars and energy gel, and distinct from sports drinks, which are advertised to enhance sports performance. There are many brands and varieties in this drink category.
Energy drinks have the effects of caffeine and sugar, but there is little or no evidence that the wide variety of other ingredients have any effect. Most effects of energy drinks on Cognition performance, such as increased attention and reaction speed, are primarily due to the presence of caffeine. Other studies ascribe those performance improvements to the effects of the combined ingredients.
Advertising for energy drinks usually features increased muscle strength and endurance, but there is no scientific consensus to support these claims. Energy drinks have been associated with many health risks, such as an increased rate of injury when usage is combined with alcohol, and excessive or repeated consumption can lead to cardiac and psychiatric conditions. Populations at risk for complications from energy drink consumption include youth, caffeine-naive or caffeine-sensitive, pregnant, competitive athletes and people with underlying cardiovascular disease.
There is no reliable evidence that other ingredients in energy drinks provide further benefits, even though the drinks are frequently advertised in a way that suggests they have unique benefits. The dietary supplements in energy drinks may be purported to supply benefits, such as for vitamin B12, but no claims of using supplements to enhance health in otherwise normal people have been verified scientifically.
Marketing of energy drinks has been particularly directed towards teenagers, with manufacturers sponsoring or advertising at extreme sports events and music concerts, and targeting a youthful audience through social media channels.
According to the Mayo Clinic, it is safe for the typical healthy adult to consume a total of 400 mg of caffeine a day. This has been confirmed by a panel of the European Food Safety Authority (EFSA), which also concludes that a caffeine intake of up to 400 mg per day does not raise safety concerns for adults. According to the EFSA this is equivalent to 4 cups of coffee (90 mg each) or 2 1/2 standard cans (250 ml) of energy drink (160 mg each/80 mg per serving).
Adverse effects associated with caffeine consumption in amounts greater than 400 mg include nervousness, irritability, sleeplessness, increased urination, abnormal heart rhythms (Heart arrhythmia), and dyspepsia. In the United States, caffeine dosage is not required to be displayed on product labels for food. However, companies often place the caffeine content of their drinks on the label regardless, and some advocates are urging the Food and Drug Administration (FDA) to change this practice.
The consumption of caffeinated energy drinks has been associated with adverse effects on cardiovascular health, including increased heart rate and blood pressure, which can pose risks for individuals with underlying heart conditions.In Europe, energy drinks containing sugar and caffeine have been associated with the deaths of athletes. Reviews have noted that caffeine content was not the only factor, and that the cocktail of other ingredients in energy drinks made them more dangerous than drinks whose only stimulant was caffeine; the studies noted that more research and government regulation were needed.
The American Academy of Pediatrics recommends that children do not consume caffeinated energy drinks. For children and teenagers, safe levels of caffeine consumption have not been established.
In 2011 in the United States, 11% of the 20,783 people aged 12 or older who visited the emergency room for issues related to energy drinks were hospitalized. The number of energy-drink related emergency room visits in the United States doubled between 2007 and 2011.
In 2012, federal officials had received reports of 13 deaths over the previous four years that cited some possible involvement of 5-Hour Energy, which is classified as an energy shot, or a subsection of the energy drink category. Between 2009 and 2012, 5-Hour Energy had been mentioned in 90 filings with the F.D.A., including more than 30 that involved serious or life-threatening injuries like heart attacks, convulsions, and in one case, a spontaneous abortion.
While caffeine is traditionally not seen as a drug of abuse, there is growing discussion that its use—especially in the form of energy drinks—may exhibit a "Gateway drug effect," increasing the likelihood of subsequent use of alcohol and other substances; Students who regularly consume caffeinated energy drinks have a greater risk of alcohol use disorder, cocaine use and misuse of prescription stimulants. The elevated risk remains after accounting for prior substance use and other risk factors. Controlled animal and human studies showed that caffeine from energy drinks in combination with alcohol increased the craving for more alcohol more strongly than alcohol alone. These findings correspond to epidemiological data that people who consume energy drinks generally showed an increased tendency to take alcohol and other substances.
In Europe, Dietrich Mateschitz, an Austrian entrepreneur, introduced the Red Bull product, a worldwide bestseller in the 21st century. Mateschitz developed Red Bull based on the Thai drink Krating Daeng, itself based on Lipovitan. Red Bull became the dominant brand in the US after its introduction in 1997, with a market share of approximately 47% in 2005.
In New Zealand and Australia, the leading energy drink product in those markets, V, was introduced by Frucor. The product now represents over 60% of market in New Zealand and Australia.
In 2002, Hansen Natural Company introduced the energy drink Monster Energy. Hansen Natural Company changed their name to Monster Beverage after an agreement by shareholders to change the name after Monster Energy became the largest source of revenue. The company's previous beverages were taken ownership of by the Coca-Cola Company.
The energy shot product, an offshoot of the energy drink, was launched in the US with products such as 5-Hour Energy, which was first released onto the market in 2004. A consumer health analyst explained in a March 2014 media article: "Energy shots took off because of energy drinks. If you're a white collar worker, you're not necessarily willing to down a big Monster energy drink, but you may drink an energy shot."
In 2007, energy drink powders and effervescent tablets were introduced, whereby either can be added to water to create an energy drink.
On 14 August 2012, the word energy drink was listed for the first time in the Merriam-Webster's Collegiate Dictionary.
Caffeinated alcoholic drinks are also sold in some countries in a wide variety of formulations. The American products Four Loko and Joose originally combined caffeine and alcohol before caffeinated alcoholic drinks were banned in the US in 2010.
In the United States, the caffeine content of energy drinks is in the range of 40 to 250 mg per 8 fluid ounce (237 ml) serving. The FDA recommends that 400 mg per day is safe for adults (excluding pregnant people), while 1200 mg per day can be toxicity.
The global energy drink market was estimated to be worth $45.80 billion in 2020 and is predicted to grow at an annual rate of 8.2% to reach $108.40 billion by 2031.
73 countries and territories have implemented policies such as taxation, bans within schools, sale bans, labeling, and marketing restrictions on energy drinks, usually to reduce consumption among those under 18.
In 2009, a school in Hove, England, requested that local shops refrain from selling energy drinks to students. Headteacher Falklanda Sanders added that "This was a preventative measure, as all research shows that consuming high-energy drinks can have a detrimental impact on the ability of young people to concentrate in class." The school negotiated for their local branch of the Tesco supermarket to display posters asking students not to purchase the products. Similar measures were taken by a school in Oxted, England, which banned students from consuming drinks and sent letters to parents.
While not yet age-restricted by legislation, all major UK supermarkets have agreed to voluntarily stop the sale of energy drinks to under-16s. The UK government plans to end the sale of energy drinks to under-16s in the future.
In January 2018, many United Kingdom supermarkets banned the sale of energy drinks containing more than 150 mg of caffeine per liter to people under 16 years old; this was followed by the UK government announcing that it planned to ban all sales of energy drinks to minors in 2019. However, in 2022 such plans were reported to have been scrapped by Health Secretary Sajid Javid.
Some places ban the sale of prepackaged caffeinated alcoholic drinks, which can be described as energy drinks containing alcohol. In response to these bans, the marketers can change the formula of their products.
In terms of labeling, caffeine must be disclosed on the product label. The specific amount of caffeine, however, does not have to be specified.
In 2013, the US Senate Commerce Committee requested 16 energy drink manufacturers to voluntarily agree not to market to children under 18.
In 2014, the American Beverage Association published the "Guidelines for the Responsible Labeling and Marketing of EDs" encouraging companies that produce energy drinks to voluntarily report the total caffeine content from all sources, limit marketing to children, and report adverse health effects to the Food and Drug Administration.
