L-carnitine plays a key role in the transport of higher fatty acids in the mitochondria, where they are oxidized to form ATP (fat is converted into energy needed by the body), thereby promoting fat utilization. The next function of L-carnitine is to provide a sparing effect on proteins (by preventing the use of amino acids for energy needs). It is necessary to maintain optimal physiological condition and normal muscle function (the content of L-carnitine in muscle tissue is 20-50 mg/kg), and is involved in the processes of energy supply to muscle tissue, in particular the heart muscle. L-carnitine is effective for heart failure, angina pectoris, and arrhythmias. It effectively improves exercise tolerance in both sick and healthy people. The dietary supplement L-carnitine helps reduce cholesterol and triglycerides, normalizes fat metabolism in the liver, inhibits the development of atherosclerosis, improves metabolism, improves liver function (this is of great importance for people suffering from alcoholism) and also promotes the removal of metabolites, toxic substances and so-called "carbon waste". Dietary supplement L-carnitine helps the body manage its energy reserves more efficiently, that is, it can be used to increase the body’s endurance and improve heart function. It helps reduce subcutaneous fat, increase muscle mass, more quickly restore the body after training, and generally has a beneficial effect on the condition of people involved in sports. Athletes often have a deficiency of L-carnitine, as a result of which cardiac activity worsens and the content of triglycerides in the blood increases. During training and competitions, the supply of glycogen is saved, the supply of oxygen to cells is significantly improved, which explains the increased endurance.
