Caffeine is a widely consumed stimulant found in coffee, tea, energy drinks, and various supplements. While moderate caffeine consumption is generally safe for most adults, understanding the risks of caffeine overdose is crucial for preventing potentially dangerous situations. This comprehensive guide explores safe consumption limits, warning signs, and when to seek medical attention.
