Does caffeine in tea affect the body differently than the caffeine in coffee?

Answer 1

A cup of coffee tends to have much more caffeine than a cup of tea.

Tea (including black tea, green tea, white tea, oolong tea, etc.) tends to have about 15-70mg of caffeine per 8 oz. cup, whereas the same size cup of coffee tends to have about 80-135mg of caffeine. You cannot generalize about one type of tea (black, green, etc.) containing more or less caffeine.

However, by dry weight, tea actually contains substantially more caffeine than coffee. This fact can be misleading, since when brewing coffee, one uses more coffee grounds by weight than one uses tea. Tea is very light, and typically, only 2-3 grams of loose tea leaf are steeped to produce an 8 oz. cup of tea.

The brewing method for tea (and to some degree for coffee) can have a large effect on the caffeine content. For tea, using more leaf, and steeping for longer times, can result in a much higher caffeine content in the finished cup.

Answer 2

For me, I would say yes! After I changed my beverage from coffee to tea, I don't get migraines any more and tea doesn't make me feel so dehydrated.

From what I've gathered, it is said that tea leaves in their dry form has more caffeine than coffee beans, but after brewing the tea the caffeine would be lower than the brewed coffee.

Answer 3

A cup of black tea has half the amount of caffeine than a cup of coffee, and a larger amount of antioxidants such as plant polyphenols, flavonoids, catechins, and tannins. Coffee does not have some these properties present, yet does have its share of minerals.

But coffee does have its advantages over tea in some areas. As just mentioned, take the simple fact that if you can tolerate caffeine, coffee is a great stimulant, and is helpful in waking folks up in the morning. People also prefer the stronger taste of coffee when having breakfast over the lighter flavor of tea.

Answer 4

There is no difference in the ways that caffeine from different sources will affect the body. The caffeine from tea will act the same as the caffeine from coke, chocolate, coffee, red bull, or any other caffeine-containing product. However, there are differing levels of other chemicals in tea and coffee that will affect you, as well as the differing caffeine concentrations. Theobromine and Theophylline are two chemicals of the many that are found in differing concentrations between these two drnks, and these may affect you in different ways. But before comparing the caffeine in Tea and Coffee, first check the concentrations of caffeine in these drinks- although the tea leaf has more caffeine in it, not all of this is released, and as such coffee is typically much stronger in terms of caffeine than tea, and so will affect you more.
