It is impossible to say exactly how much caffeine is contained in a cup of coffee. The grade, dosage, pretreatment, and brewing method are important here. Therefore, it is only possible to estimate its quantity approximately. A serving of cappuccino (300 ml) contains approximately 100 mg of caffeine. Americano (300 ml) - 160 mg. Filter coffee (300 ml) - 150 mg. Espresso (100 ml) - 200 mg. Instant coffee (1 tsp dry powder) - 40-60 mg. Therefore, do not consume more than 3-4 cups (150 ml each) of the drink per day. It was this amount of research that allowed us to get the maximum benefit. Excessive consumption can already have a negative effect on the body.

This way you can definitely avoid side effects. In addition, caffeine is also found in tea, carbonated sugary drinks, cocoa and chocolate. Consider this.
