Standardized grape seed extracts can be an effective aid in facing damage caused by free radicals, such as cellular aging, cardiovascular disorders, or DNA damage. Due to their high antioxidant capacity, they counteract the damaging effects caused by excess free radicals produced physiologically by the body or by external sources such as UV rays or cigarette smoke. Grape seed extract was also demonstrated to protect against bacterial infections, such as Staphylococcus aureus infections.
