What caffeine is and how it works in the body
Caffeine is the most studied stimulant in the world. Unlike what many people think, it does not create energy from nothing: it works by blocking adenosine receptors in the brain, the molecule responsible for the feeling of tiredness, allowing alertness neurotransmitters like dopamine and noradrenaline to act with greater intensity.
In Stay Focus, 80mg of anhydrous caffeine per dose is combined with Korean ginseng, ginkgo biloba, magnesium and a complete B vitamin complex, creating a synergistic effect that goes beyond immediate energy: it supports concentration, mental clarity and cognitive endurance throughout the day.
Unlike coffee, Stay Focus does not cause sharp energy spikes followed by a sudden crash. The combination of caffeine with B vitamins and magnesium produces a smoother, more progressive and longer-lasting effect.
Acts in 15 to 45 minutes
Caffeine is absorbed quickly by the body, with peak effect between 30 and 60 minutes after taking it.
80mg per dose
Equivalent to one espresso, but with a smoother effect thanks to the combination with B vitamins and magnesium.
Blocks tiredness
Caffeine does not create energy. It blocks the adenosine receptors that make us feel sleepy and unfocused.
