In addition to its ability to increase the metabolic rate, green tea is a powerful antioxidant, being destroyer of free radicals.

This formulation provides 259mg of catechins from green tea leaves with the important amino acid L-Theanine. Each tablet corresponds to a ½ liter green tea. Suitable for vegetarians
