In brief: 200-300mg
200-300mg of caffeine daily (equivalent to 2-4 cups of coffee) is generally thought to be safe for most adults, although this amount varies widely depending upon your metabolism & sensitivity.
Once you hit 500-600mg daily, your risk for side effects increases and tends to outweigh any benefits.
