• Conclusions:– Supplementation with carnitine, taurine and Co-Q10

resulted in higher myocardial levels of the ingredients

– These higher levels improve myocardial function

– After supplementation the time to exhaustion is larger

– Supplementation leads to a reduction of end diastolic volume

– This reduction improves prognosis for cardiac diseases
