What is High caffeine?
High caffeine refers to any ingredient or product with a significant amount of caffeine, a natural stimulant most commonly found in coffee beans, tea leaves, and other plant sources. It's often extracted and added to energy drinks, supplements, and various caffeinated products.
Caffeine is used for its stimulating effects on the central nervous system, which can increase alertness and reduce fatigue. Scientific evidence shows caffeine can improve attention and physical performance, but it may also lead to increased heart rate, anxiety, or sleep disturbances in sensitive individuals, especially in high doses.
When you see 'high caffeine' on a label, it indicates a product with a caffeine content significantly above the average for typical caffeinated beverages, so it's important to be mindful of your total daily caffeine intake.
