Euro RSCG Wnek Gosper has produced the TV and radio campaign, which takes a humorous approach to promoting the bar's claimed invigorating properties.
The advertising, breaking next Tuesday, aims to turn Boost Guarana into a potent competitor to other energy-enhancing products such as Lucozade and Red Bull in the £750 million sector.
Carat is handling media planning and buying for the campaign, which is targeted at 16- to 24-year-old males looking for a rapid energy rush.
The bar was launched in the UK six months ago.
In the TV spot, a tyre changer is turned into an ace tyre tightener in a Grand Prix pit team. But his super ability is found to come from Boost Guarana and, disgraced, he ends up handing out inner tubes to kids at a water park. The film ends with the line "Without it you're nuffing".
The radio work sustains the theme of people performing spectacularly, including a milkman who completes the rounds for the entire dairy.
The TV campaign was written by Neil Williams, art directed by Ed Bones and directed by Pedro Romhanyi through Outsider.
