The brand has partnered with David Beckham, and is the first to be granted rights to use his image and signature on packaging and marketing material.
GO3 plans to roll out its range of Omega-3 fish oil supplements, including a Junior Strawberry children's variant, in the autumn.
The packaging and logo, which was designed by Smith & Milton, is intended to appeal to all ages.
GO3 is owned by Norwegian businessman Geir Srantzen, who also owns frozen-foods brand Findus.
