A 500ml Monster Energy can contains 160mg of caffeine and 55g of sugar. The caffeine is double that of a standard Red Bull 250ml can and equivalent to roughly two medium espressos in a single container. The salt content (0.20g per 100ml) is also higher than most energy drinks, contributing to an electrolyte profile that partially supports the 'sports drink' positioning. Monster's distinctive claw logo and black branding is targeted primarily at males aged 18-35.
