CAFFEINE GUIDE

Track caffeine daily and choose drinks with confidence

Caffeine Tracker is a free caffeine lookup and daily intake tool. Compare caffeine by brand, drink and size, log when and how much you drink, and review your daily and monthly totals.

Tracking and metabolism estimates

The tracker totals your daily intake and uses a simplified five-hour half-life model to estimate caffeine remaining in your body. Metabolism varies with individual health, pregnancy, smoking and medication, so results are for everyday reference only.

Transparent drink data

The drink database separates official brand values, careful estimates and statistical averages by size. Official values take priority, while estimates are clearly identified instead of being presented as laboratory measurements.
