There is a special biological interrelationship between Coenzyme Q10 and selenium. From a cardiologist’s perspective, there is a theoretical advantage in using both substances to prevent heart disease if the patients’ intakes are sub-optimal [Alehagen & Aaseth 2015a].

This advantage has been demonstrated in the outcomes of the KiSel-10 Study, a randomized controlled trial that enrolled elderly community dwelling Swedish citizens, average age 78 years, with known low serum selenium status (mean: 67.1 mcg/L) [Alehagen 2013; Alehagen 2016a; Alehagen 2016b].
