This is a question researches are still squabbling over. Does green tea have more antioxidants than black tea? Should I drink instant tea or loose leaf tea for better health benefits? Is hot tea better than iced tea? And here’s what it comes down to: . Higher quality teas may have more catechin antioxidants than lower quality teas.. White tea has more antioxidants than any other tea.. Green tea has more catechin antioxidants than black tea since black tea goes through more processing.. Unfermented ratios tea has more polyphenol antioxidants than fermented ratios.. Freshly brewed teas have more polyphenol antioxidants than instant or bottled teas.. More researches seem o agree that brewed (cold or hot) or caffeinated tea has more antioxidants than instant teas.
