Antioxidants have been linked to a range of health benefits, from the prevention of things like cardiovascular disease to the delaying of the ageing process. These compounds, which are widely present in the tea leaf in the form of polyphenols, help counter the harmful effects of ‘free radicals’ and decrease cell damage in the body. Tea is also a source of vitamin C, B1 and B6, and as well as the minerals manganese, essential for bone growth, and potassium, vital for maintaining body fluid levels.
