Green tea extract ideal to accompany a balanced diet and maintain the line. It is believed that green tea (Camellia sinensis) gently increases the metabolic rate (the ability to convert food into energy). It is also a powerful antioxidant and free radical scavenger. These effects are due to compounds called catechins (polyphenols), which are present in high-quality green tea leaf extracts. It also provides the important compound L-theanine. A single tablet is equivalent to ½ litre of traditionally brewed green tea and contains a fraction of the caffeine content.
