amount of caffeine in coffee cup
Most people slowing their caffeine intake say that reducing their daily fix by a rate of 1/2 cup of coffee a day makes the change relatively pain-free. Others count their weekly intake and aim for three to five cups less per week. Decaf coffee from Dunkin Donuts may also contain quite a bit of caffeine. According to one source, a small cup (10 oz) has 53 mg of caffeine, and a large cup (24 oz) contains 128 mg (13). That’s almost as much caffeine as you find in other varieties of regular coffee. Your daily caffeine intake can add up quickly, especially when 16 ounces at many coffee shops is the norm. Plus, if you drink iced coffee, the portions tend to be large and usually aren’t watered down so a majority of the cup is coffee. The sweet spot seems to be no more than 4 cups or 400 milligrams of coffee a day to get the health benefits and curb your cravings without any side effects. But the right amount really depends on how it makes you feel. How much is too much? Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That's roughly the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two energy shot drinks. Although caffeine use may be safe for adults, it's not a good idea for children. And adolescents should limit themselves to no more than 100 mg of caffeine a day. Coffee: How much is too much caffeine? If you need your morning coffee to wake up and several more cups to get through the day, you may worry that your habit isn’t healthy. Although experts say coffee is one of the best beverages you can drink, too much caffeine can have serious side effects. Also known as regular coffee, brewed coffee is made by pouring hot or boiling water over ground coffee beans, usually contained in a filter. One cup of brewed coffee (8 oz) contains about 70–140 mg of caffeine, or about 95 mg on average (1, 2). Coffee is the biggest dietary source of caffeine. You can expect to get around 95 mg of caffeine from an average cup of coffee. However, this amount varies between different coffee drinks, and can range from almost zero to over 500 mg. This is a detailed guide to the caffeine content of different types and brands of coffee. Drinking coffee can also increase energy and improve memory, reaction time and mood. In fact, a study out of the Harvard School of Public Health found that people who drink two to four cups of coffee a day reduce their risk for suicide by 50 percent. Bottom Line: The average caffeine content of an 8-oz, brewed cup of coffee is 95 mg. A single espresso or espresso-based drink contains 63 mg, and decaf coffee contains about 3 mg of caffeine (on average).
