The Swedish cardiologist Dr. Urban Alehagen has written persuasively that there exists a special inter-relationship between selenium and Coenzyme Q10 in the prevention of cardiovascular diseases.
Briefly, Prof. Alehagen, together with the Norwegian professor Jan Aaseth, makes the point that low selenium intakes and status could restrict the cells’ ability to get optimal concentrations of Coenzyme Q10 and that the cells need adequate of Coenzyme Q10 to permit optimal function of selenium [Alehagen & Aaseth 2015a].
The clinical outcomes of the KiSel-10 intervention study in which community living Swedish citizens, average age 78 years, were administered selenium and Coenzyme Q10 daily for four years show that combined selenium and Coenzyme Q10 supplementation, compared to placebo treatment, can be beneficial in populations that have low selenium status:
