Can selenium supplementation help to prevent cardiovascular disease

Research into the efficacy of selenium and cardiovascular disease (CVD) prevention is characterised by uncertainty. Evidence from large ongoing trials is needed to establish whether low selenium concentrations are a definite risk factor for CVD in healthy populations, yet certain individuals may benefit from supplementation, according to a leading cardiologist. Professor Hosen Kiat, Professor of Medicine & Cardiology, said, “Whilst evidence thus far may not support the supplementation of selenium as a preventative measure for CVD for healthy patients with an adequate dietary selenium intake and normal serum levels, this needs to be distinguished from the importance of adequately addressing dietary or disease related selenium deficiency with oral selenium supplementation.”
