Green Tea Extract

Green tea extract is derived from the leaves of Camellia sinensis and is a rich source of catechins, which are polyphenolic antioxidants. It is included in some dog foods in small quantities for its antioxidant and anti-inflammatory properties. However, green tea contains caffeine, and care must be taken to ensure that the levels used are low enough to be safe. At the trace amounts typically used in pet food formulation, it is generally considered safe, but it offers modest practical benefit at such concentrations.
