CoQ10 has been studied in humans and reviewed extensively in the scientific literature; it has been documented to be beneficial in promoting cardiovascular health. A number of studies indicate that supplementation with CoQ10 supports healthy heart function, including maintenance of a normal heartbeat and the metabolism of oxygen in the heart. Furthermore, research shows that individuals with hypertension and angina may experience a faster loss of CoQ10 during exercise. In these instances, supplementation may help increase blood levels of CoQ10, while supporting the ability to exercise longer.
