Caffeine 200mg tablets are an effective stimulant used to enhance energy levels, alertness, and cognitive function. Caffeine is the most widely used psychoactive substance in the world, primarily due to its ability to increase mental focus and reduce fatigue. These tablets are commonly taken by individuals looking to stay awake and alert during long hours of work or study, and they are often used by athletes to improve performance. The recommended dosage should not exceed 400mg of caffeine daily to avoid side effects such as anxiety, jitteriness, and increased heart rate. While caffeine is generally safe in moderate amounts, excessive consumption can lead to dependency and other health issues.
