Method and limits

The caffeine figure comes from blog.buckedup.com; recipes, brewing and batches vary, so a real serving can differ. The curves use a standard one-compartment model with an average 5-hour half-life and a sleep-friendly line of 50 mg; your own body may clear caffeine faster or slower. How it works has the details.

These are estimates for information, not medical advice. If you are pregnant, ask your doctor; common guidance is under 200 mg a day.
