Understand your personal limits and make informed choices about your favorite caffeinated beverages for better health and wellbeing. This tool is designed for adults to promote responsible caffeine consumption.
Formula:
The calculator estimates your recommended daily caffeine limit for adults based on your body weight using the following formula:
Recommended Daily Caffeine Limit (mg) = Body Weight (kg) × 5 mg/kg
Important Note: For most healthy adults, the generally accepted maximum caffeine intake is 400 mg per day. This calculator will cap the recommended limit at 400 mg, even if your body weight suggests a higher potential amount.
- Body Weight (kg): Your body weight in kilograms.
- 5 mg/kg: A commonly used guideline for a moderate, safe daily caffeine dose for healthy adults.
