- Polyphenols: In addition to catechins, the extract contains other polyphenol compounds such as flavonoids. These polyphenols contribute to the overall antioxidant capacity of Green Tea Extract. They also play a role in modulating various biological processes in the body, including cell signaling and enzyme activity.
- Theanine: Theanine is an amino acid unique to tea plants. It is present in significant amounts in Green Tea Extract. Theanine has a calming effect on the nervous system and can promote relaxation without causing drowsiness. It also has the potential to enhance cognitive function, including attention, focus, and mental alertness.

Cosmetics and Personal Care
- Skin Care Products: Green Tea Extract is a popular ingredient in skin care products.

Pharmaceutical and Nutraceutical
- Natural Medicine: Green Tea Extract is used in the development of natural medicine products. It may be used as a single - ingredient product or in combination with other natural substances to treat or prevent various health conditions. For example, it is being studied for its potential role in preventing certain types of cancer, as well as in managing metabolic syndrome.
- Nutraceutical Formulations: In the nutraceutical industry, Green Tea Extract is used in a variety of formulations. It can be combined with other nutrients like vitamins, minerals, and other herbal extracts to create comprehensive health - promoting supplements. These formulations are designed to target specific health concerns, such as cardiovascular health, immune support, and cognitive function.
Function:
- Antioxidant Protection: The high concentration of antioxidants, especially catechins, in Green Tea Extract provides robust protection against oxidative stress. Oxidative stress is caused by an imbalance between free radicals and the body's antioxidant defenses, and it is associated with various diseases, including cancer, heart disease, and neurodegenerative disorders. By neutralizing free radicals, Green Tea Extract helps to reduce cellular damage and inflammation, promoting overall health.
- Weight Management: Some studies suggest that Green Tea Extract may aid in weight management. The catechins, particularly EGCG, can increase metabolism and fat oxidation. This means that the body may burn more calories and fat, potentially leading to weight loss or weight maintenance. Additionally, theanine in the extract can help reduce stress - related overeating, which is a common factor contributing to weight gain.
- Heart Health: Green Tea Extract has been linked to improved heart health. It can help lower cholesterol levels, particularly LDL (bad) cholesterol, and reduce blood pressure. The antioxidants in the extract also prevent the oxidation of LDL cholesterol, which is a key step in the development of atherosclerosis. By improving these cardiovascular risk factors, Green Tea Extract may help reduce the risk of heart disease.
- Cognitive Function Enhancement: Theanine in Green Tea Extract, in combination with caffeine (present in small amounts), can enhance cognitive function. Theanine promotes relaxation and reduces anxiety, while caffeine provides a mild stimulant effect. Together, they can improve mental alertness, concentration, and memory. This makes Green Tea Extract a potential supplement for those looking to boost their cognitive performance.
