How to Take It
Best taken in the morning
Morning or early afternoon only — caffeine within 8 hours of bed measurably disrupts sleep.
With or without food
On the label
Take one tablet no more than every three to four hours, up to a maximum of 1000 mg (5 tablets) in 24 hours. There is 200 mg of caffeine in one tablet, about as much as in a large, strong cup of coffee.
General guidance based on the ingredients, not a substitute for the label or your doctor.
