Wakefulness and attention
What drives the caffeine response.
Caffeine acts on the central nervous system, temporarily reducing the effect of sleepiness signals. That is the main reason people use it when they want to feel more awake. Wakequill combines a 50 mg caffeine serving with L-theanine and vitamin B12. B12 contributes to normal blood and nerve function, while theanine is an amino acid studied alongside caffeine. The combination keeps these roles distinct: nutritional support from a vitamin is different from the short-term stimulation caffeine can produce.
