Green tea extract
Green tea extract is a herbal derivative from green tea leaves (Camellia sinensis). Containing antioxidant ingredients – mainly green tea catechins (GTC) – green tea and its derivatives are sought after for their health benefits.
History[edit | edit source]
Green tea has been consumed in China and other parts of Asia for centuries. The medicinal properties of green tea extract are significantly concentrated and many people will consume green tea supplements for this reason.
Composition[edit | edit source]
Green tea extract is rich in several types of polyphenols, which are a type of antioxidant. The most abundant catechin in green tea is epigallocatechin gallate (EGCG), which is thought to play a pivotal role in the green tea's anticancer and antioxidant effects.
Health Benefits[edit | edit source]
Green tea extract has been shown to have a positive effect on health issues such as weight loss, liver disorders, type 2 diabetes, Alzheimer's disease, and more. However, more research is needed to fully understand the extent of these benefits and the optimal dosage.
Side Effects[edit | edit source]
While green tea extract is generally well tolerated, it can cause stomach problems, headache, and dizziness. It has also been linked to liver problems in rare cases.
