Caffeine is a common stimulant found in both tea and coffee, which can be enjoyed in a variety of forms: brewed, espresso, or in capsule form from a single-serve coffeemaker. Caffeine affects the body's central nervous system, providing mental and physical energy and alertness. However, there are some key differences between the caffeine in tea and the caffeine in coffee that affect its stimulating properties.
Caffeine in tea is generally considered to be of higher quality than caffeine in coffee. Tea leaves contain higher concentrations of caffeine, approximately 40-70mg per cup compared to coffee, which contains 20-100mg per cup (CNBC). This makes tea a more concentrated source of caffeine, and therefore more efficient at providing an energizing effect. In addition, tea's unique plant compound, theanine, seems to increase the calming effects of caffeine and reduce the jittery feeling associated with drinking too much coffee (Healthline).
The type of caffeine found in tea may also have a gentler effect on the stomach than coffee's caffeine. Unlike coffee, most teas are not acidic and do not contain oils that irritate the stomach (Bon Appetit). Tea's lower acidity and reduced bitterness can help to combat common digestive symptoms like reflux, bloating, and upset stomach.
Although tea and coffee both contain caffeine, it is clear that there are a few differences that must be taken into consideration when deciding which to enjoy. Tea's higher quality caffeine, coupled with its calming theanine and lower acidity levels, make it a more digestible choice when seeking an energy boost, particularly for those with sensitive stomachs.
