The way caffeine impacts sleep and fatigue varies greatly due to individual metabolic differences and sensitivities. In general, caffeine’s half-life (meaning the amount of time it takes for the consumed quantity to halve in the bloodstream) lasts between 2-12 hours, with a common average of around six, meaning it tends hang around in your system for a while.
Given caffeine works as an adenosine blocker, this can be detrimental to your sleep, especially if you have large doses within 3-6 hours of your bedtime. As we all know, sleep is crucial for both neurological and physiological recovery, meaning it is advisable to avoid large caffeine intakes later in the day.
It’s in these scenarios that products like Zuum Energy Gum can be especially useful.
Unlike pre-workouts, coffees and energy drinks, which contain 80mg + of caffeine per serving, each piece of Zuum is formulated with the half-life effects of caffeine in-mind, containing just 40mg of caffeine per piece. This allows Zuum’s athletes to strategically control their caffeine boost for when they need it, whilst leaving the body in time for when you don’t, allowing them to charge through an evening work-out with the importance of rest and recovery firmly in mind.
