Energy drinks contain one ingredient doing nearly all of the work and several that are mostly there for the label.
What is actually active
Caffeine, at amounts varying widely between products, does most of what an energy drink does. Sugar contributes a rapid glycaemic effect followed by a fall. Taurine is present in substantial amounts and its contribution is not well established, with research not clearly demonstrating an independent effect at these doses. B vitamins are present, generally well above requirement, and have no acute energy effect in people who are not deficient despite the energy positioning.
Combination claims
Marketing frequently claims synergy between caffeine, taurine and glucuronolactone. Studies examining the combination against caffeine alone have generally not demonstrated effects clearly attributable to the additional components. The reasonable conclusion is that most of the effect is caffeine plus sugar, and that a coffee costs less and delivers the caffeine without the sugar load.

See Cognizil PricingThe risks
Total caffeine intake is the main issue, since some products contain amounts comparable to several coffees in a single serving and are consumed rapidly rather than sipped. Cardiovascular events have been reported in case series, particularly with high intake, in young people, and combined with alcohol - a combination that reduces perceived intoxication without reducing impairment. Dental effects from acidity and sugar. Regular high intake in adolescents is associated with sleep problems and is worth taking seriously.
Key takeaways
- Caffeine and sugar account for nearly all of the acute effect
- Studies have not clearly shown taurine adding to caffeine at these doses
- B vitamins have no acute energy effect in people who are not deficient
- Combining with alcohol reduces perceived intoxication without reducing impairment
