Catechins are a group of polyphenolic compounds that belong to flavonoids and have powerful antioxidant properties. They are found mainly in tea (especially green tea), cocoa, red wine, blueberries, pomegranates and some other plant products. Catechins are known for their ability to neutralize free radicals, protect cells from oxidative stress, and prevent the development of many chronic diseases.
In addition to the antioxidant effect, catechins have anti-inflammatory, antimicrobial and immune-stimulating properties. They help strengthen the walls of blood vessels, reduce the level of “bad” cholesterol (LDL) and improve the general condition of the cardiovascular system. Studies also show that catechins may help normalize blood glucose levels, making them useful for the prevention of type 2 diabetes.
Green tea catechins, such as epihalocatechin-3-galate (EGCG), have antitumor properties, help in detoxifying the body, and may slow down the aging process. They also help improve metabolism, which makes them popular in products to maintain a healthy weight. Due to all these properties, catechins are important bioactive compounds that are actively used in medicine, dietetics and cosmetology.
