topicL-Carnitine Exercise Performance Randomized Trial
claimAim This review aims to provide an integrated synthesis that bridges mechanistic evidence (anti-inflammatory, antioxidant) with clinical outcomes (mortality, arrhythmias) for LC supplementation in CAD, while critically appraising inconsistencies across the literature (e.g., heart failure, reinfarction).

topicL-Carnitine Exercise Performance Randomized Trial
claimBackground Coronary artery disease (CAD) persists as a major global health burden, contributing significantly to both morbidity and mortality rates worldwide, mostly attributable to atherosclerosis and oxidative stress.

topicL-Carnitine Exercise Performance Randomized Trial
claimL-carnitine (LC), a natural derivative of amino acid, plays a critical role in mitochondrial fatty acid transport and has demonstrated potential antioxidant as well as anti-inflammatory effects.

topicL-Carnitine Exercise Performance Randomized Trial
claim1 Aging is characterized by progressive physiological decline, including loss of skeletal muscle mass and function (Sarcopenia), reduced mitochondrial efficiency, and increased oxidative stress, all of which contribute to frailty and diminished quality of life in older adults ().
