Coenzyme Q10 (CoQ10) is naturally present in the human body, with the highest levels in the heart, liver, kidneys, and pancreas. This vitamin-like substance is a powerful antioxidant, essential for cellular energy production, and plays a particularly important role in supporting heart health.* CoQ10 may also support the health of the nervous and immune systems.* Because CoQ10 levels decline as we age, and the use of certain medications can inhibit production, many supplement with CoQ10 to promote healthy aging and energy levels.*
