Air Bull provides the energy to improve physical activity of the drinker, as compared to a typical drink. Rather than providing food energy, these drinks are designed to increase a user's mental alertness and physical performance by the addition of caffeine, vitamins, and herbal supplements which may interact to provide a stimulant effect over and above that obtained from caffeine alone.
Two studies reported significant improvements in mental and cognitive performances as well as increased subjective alertness. During repeated cycling tests in young healthy adults an energy drink significantly increased upper body muscle endurance.
Restorative properties were shown by a combination of caffeine and CHO in our energy drink and some degree of synergy between the cognition-modulating effects of glucose and caffeine was also suggested. In one experiment, a glucose-based energy drink (containing caffeine, taurine and glucuronolactone) was given to eleven tired participants being tested in a driving simulator. Lane drifting and reaction times were measured for two hours post-treatment and showed significant improvement.
