An energy drink is a drink that contains stimulant ingredients, most commonly caffeine, and is marketed as giving mental and physical stimulation (marketed as “energy”, but distinct from food energy). They can be carbonated or not, and they can contain sugar, other sweeteners, herbal extracts, taurine, and amino acids. They are a subset of the larger category of energy goods that includes bars and gels, as opposed to sports beverages, which are claimed to improve athletic performance. This drink category contains numerous brands and types.

Typically, energy drinks do not include coffee, tea, or other naturally caffeinated beverages. Even though other soft drinks like cola may contain caffeine, they are not regarded as energy drinks. Buckfast Tonic Wine is one alcoholic beverage that includes caffeine and other stimulants. According to the Mayo Clinic, a total of 400 mg of caffeine per day is safe for the average healthy adult. This was validated by a panel of the European Food Safety Authority (EFSA), which also concluded that a caffeine intake of up to 400 mg per day is safe for adults. 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), according to the ESFA.
