Caffeine and Cognitive Performance

Caffeine improves cognitive performance by blocking adenosine receptors, counteracting drowsiness and enhancing reaction time, memory, and mental endurance.

Caffeine may lower the risk of neurodegenerative diseases such as Alzheimer’s and Parkinson’s due to its antioxidant and anti-inflammatory properties.

Caffeine may enhance neurogenesis and improve synaptic plasticity, both of which support learning and memory.
