What Are Energy Drinks?
What exactly are energy drinks?
Here at Fizzy Wake-Up, we define an energy drink as a cold caffeinated beverage. It doesn’t have to be carbonated, but at the same time we aren’t including the traditional caffeinated drinks such as tea and coffee. Energy drinks typically rely on the combination of sugar and caffeine to provide the consumer with a boost of energy. Some energy drinks contain other ingredients which are purported to provide additional energy boosts. Guarana, for example, is a natural source of caffeine. Vitamins and minerals such as taurine and vitamin B12 are also common ingredients. Generally they are fruit flavoured, with ‘mixed fruit’ being the most common and recognisable – we call them ‘clones’ because they are trying to taste similar to Red Bull. Just by way of comparison, an average energy drink of 250ml contains about 80mg of caffeine whereas an average single shot of espresso contains around 65mg. Most high street coffee chains ‘medium’ and ‘large’ drinks containing significantly more caffeine that this making an average energy drink roughly comparable in caffeine content to a cup of coffee.
Is caffeine safe?
Caffeine is a stimulant, so is technically a psychoactive drug which acts on your nervous system. Caffeine consumption can have serious consequences if taken to excess. It is addictive, even in small quantities when consumed regularly, and can cause nervousness, sleep irregularity, anxiety and it should be avoided altogether during pregnancy. However, in moderation it is considered safe and occasionally beneficial, sharpening reflexes and increasing alertness.
