About Caffeine Safety
Caffeine is a natural stimulant most commonly found in tea, coffee, and cacao plants. It works by stimulating the brain and central nervous system, helping you stay alert and preventing the onset of tiredness.
While caffeine is generally safe for most people when consumed in moderation, it's important to be aware of your personal limits. Factors such as body weight, medication use, individual sensitivity, and certain health conditions can affect how your body processes caffeine.
This calculator provides a general guideline based on your body weight and health conditions, but remember that everyone's sensitivity to caffeine is different. If you experience negative effects like jitters, anxiety, rapid heartbeat, or trouble sleeping, consider reducing your caffeine intake.
