Summary
Overall, L-Carnitine thus takes over a number of vital functions in the human body. The entire fat metabolism is dependent on L-carnitine being present in sufficient quantities in the human body. Above all, the heart is dependent on the energy produced by the fat metabolism.
As a result, people suffering from heart muscle diseases should take special care to supply sufficient amounts of L-carnitine to prevent a deficiency of the substance. Other groups of people who, as a result of an unbalanced diet, consume few foods in which L-carnitine occurs naturally in significant amounts also benefit from the external intake of L-carnitine. However, the promises of the fat burner L-carnitine cannot be scientifically confirmed.
Without simultaneous exercise, no decrease in body fat can be expected from an intake of L-carnitine in healthy people where sufficient amounts of L-carnitine are present in the body. In addition, current studies note that a chronically increased concentration of L-carnitine could be harmful to health and therefore, from a medical point of view, the intake of L-carnitine without a proven deficiency cannot be recommended.
