Coffee is actually the stronger pick-me-up – it has about 30 per cent more caffeine than an energy drink.
One cup (250ml) has about 104mg of caffeine, compared to about 80mg in the same amount of Red Bull energy drink, said Ms Ler Yi Bin from Mount Alvernia Hospital’s nutrition & dietetics services.
While energy drinks may contain other ingredients like taurine, glucuronolactone, herbal extracts and B vitamins, some studies claim that caffeine remains the core ingredient for their stimulatory effects.
Drink no more than three servings of caffeinated drinks day, said Ms Ler. This includes both coffee and energy drinks.
Caffeine stimulates the central nervous system, giving the body a sense of alertness. But it also increases one’s heart rate and blood pressure and dehydrates the body.
An overdose (more than 300mg) can affect your sleep pattern, quicken your heartbeat and cause headaches and dehydration.
