Caffeine

Caffeine helps restore wakefulness and reduces drowsiness, making it especially useful during periods of mental fatigue or sleepiness.

It improves accuracy, reasoning, memory, reaction time, and attention, particularly in mentally or physically demanding situations.

Caffeine can help restore cognitive abilities that are impaired due to acute sleep deprivation, improving focus and performance.

When combined with painkillers like acetaminophen or ibuprofen, caffeine enhances their effectiveness, leading to better pain relief.

It enhances endurance, strength, speed, agility, and overall exercise performance, making it widely used in sports and fitness.

Caffeine slightly boosts fat burning both at rest and during exercise, though the overall effect is relatively small.

It improves attention, reaction time, memory, and reduces mental fatigue when consumed before or during physical activity.
