Products that contain caffeine are a great way to relieve tiredness and improve mental focus. Tiredness occurs when signalling molecules build up in sufficient amounts to bind to receptors in our brain; caffeine also binds and blocks the use of these receptors stopping these tiring effects, allowing us to feel more alert.
