What is Green Tea Extract?
Green tea extract is a concentrated extract from the leaves of the Camellia sinensis plant. You will find a variety of bioactive compounds in this concentrate, especially polyphenols and catechins. The main active ingredient, epigallocatechin-3-gallate (EGCG), is characterized by its strong antioxidant properties. During production, the tea leaves are gently dried and extracted to preserve the valuable ingredients. In contrast to the infusion, the extract contains a higher concentration of active ingredients. You can take it in the form of capsules, tablets or powder. Scientific studies indicate potential health-promoting effects, including supporting the metabolism and the cardiovascular system. Note, however, that effectiveness can vary individually and further research is needed to fully understand all effects.
Where does green tea extract come from?
Green tea extract is primarily found in the leaves of the tea plant Camellia sinensis. This plant is native to various regions of Asia, particularly China, Japan and India. You can also discover the valuable ingredients in other plant species of the Camellia genus. Interestingly, some fruits such as apples and pears also contain small amounts of these substances. In nature, you often find these compounds in plants that need to protect themselves against environmental stressors. Note that the concentration of the active ingredients can vary depending on the growing region, time of harvest and processing method. Modern extraction methods allow you to use the bioactive components in concentrated form. In addition to classic green tea, you can also find these ingredients in white and oolong tea, although in different amounts.
