How Daily Caffeine Intake Is Calculated

Daily Caffeine Intake represents the sum of all milligrams consumed from various sources like coffee, tea, and medication. This calculation compares your total consumption against recommended safety guidelines.

Total Intake = (Coffee cups × 95mg) + (Tea cups × 26mg) + (Soda cans × 95mg) + (Chocolate servings × 9mg) + (Meds ? 100mg : 0)

The calculation follows these steps:

  1. First, we calculate total milligrams by multiplying your drink count by standard caffeine content.
  2. Next, we compare your total to a recommended limit based on your age group, such as 400mg for adults.
  3. Finally, we adjust the limit based on your sensitivity score to provide a personalized safety percentage.

This method relies on FDA and AAP standards to ensure your results are medically grounded and accurate.

What Your Daily Caffeine Intake Means

Your result shows the total caffeine in your system and compares it to safe limits for your specific body type and age group.

General Health Maintenance

For most healthy adults, a result between 100mg and 400mg is considered safe and moderate. However, going above 400mg can lead to restlessness, an upset stomach, or a fast heart rate.

Pregnancy Safety

If you are expecting, your result should ideally be below 200mg. Staying within this range helps ensure the safety and healthy development of your baby.

Managing Anxiety and Sleep

If you suffer from anxiety or have trouble sleeping, keeping your intake under 100mg is often best. Lower amounts help reduce the risk of increased heart rate, panic attacks, or nervousness.

Important Note: Everyone metabolizes caffeine differently due to genetics, so always listen to your body.
