Green Tea supplements and its extracts serve the best purpose to help body fight off these mechanisms called free radicals.
In our modern life many dietary supplements such as vitamin C and E, Selenium, Manganese, Copper, Zinc, Beta-Carotene etc., are widely used. However, the best one so far is Green tea (Camellia Sinensis) which is wide used all over the globe. Originally from China, Green tea migrated to Japan and the rest of the world by the 17th century. This has wide uses as it has the best and highly concentrated dose of antioxidants. There are three main varieties of tea, Green, Black, and Oolong. The difference between these teas is in their processing. Green tea is made from unfermented leaves and reportedly contains the highest concentration of powerful antioxidants called Polyphenols.
