In a randomized clinical trial involving patients suffering from chronic heart failure, the effect of dietary supplements containing a vitamin-mineral combination was investigated. The study was carried out at the Charité Clinic in Berlin and showed that the pumping function of the heart (left ventricular ejection fraction) was significantly improved by the dietary supplement. The patients’ quality of life also improved significantly. Further details can be found in the study.
