Green tea extract is a concentrated form of green tea that contains higher levels of beneficial compounds, including catechins, polyphenols, and amino acids, compared to the amount found in brewed green tea. Green tea is made from the leaves of the Camellia sinensis plant, the same plant used to produce black and oolong teas, but it is processed differently, which leads to a higher content of certain beneficial components.

Catechins: The most abundant catechin in green tea is epigallocatechin gallate (EGCG), which is known for its potent antioxidant properties.
Antioxidant Properties: The polyphenols in green tea extract act as antioxidants, which may help protect cells from damage caused by free radicals.
Weight Management: Some studies suggest that the caffeine and EGCG in green tea extract may help with weight loss by boosting metabolism and increasing fat oxidation.
Brain Function: Green tea extract may have neuroprotective effects and is believed to improve brain function, including memory and learning.
Heart Health: It may help lower the risk of heart disease by improving blood flow and reducing blood pressure, inflammation, and the formation of clots.
Cancer Prevention: Laboratory studies have shown that green tea components may slow the growth of certain cancer cells, but more research is needed to confirm these effects in humans.
Oral Health: The antimicrobial properties of green tea may help reduce plaque and improve gum health.
Skin Health: Topical applications of green tea extract have been used for their anti-inflammatory and antioxidant effects on the skin.
