| Coffee | 95-200 |
From this comparison, it’s clear that coffee generally contains significantly more caffeine than green tea. This fundamental difference is just one aspect of the conversation regarding their effects on the body.
The Mechanism of Caffeine Absorption
Understanding how caffeine is absorbed in the body offers insight into the experience one feels after consuming green tea or coffee.
Caffeine in Green Tea
The caffeine in green tea is absorbed more slowly due to the presence of an amino acid called L-theanine. This compound is known for its calming effects, which can temper some of the stimulating properties of caffeine, providing a more balanced and sustained energy boost. As a result, green tea may foster improved focus without the jitteriness often associated with coffee.
Caffeine in Coffee
Coffee, on the other hand, tends to deliver a rapid spike in caffeine levels into the bloodstream, leading to a quicker onset of alertness. However, this can also translate to a more abrupt decline in energy as the caffeine wears off, often leaving drinkers feeling fatigued or moody.
