How Much Daily Caffeine Is Too Much?

Determining your daily caffeine threshold depends on several factors, including age, weight, and individual sensitivity.

Generally, health experts recommend limiting daily caffeine intake to 400 milligrams for most adults, which is approximately the amount found in four 8-ounce cups of brewed coffee. (1)
