Zusammenfassung
Der natürliche Stoff L-Carnitin transportiert langkettige Fettsäuren vom Zytosol ins
Innere der Mitochondrien, wo sie verbrannt werden. Es ist somit Schlüsselsubstanz
für die Energiegewinnung aus Fetten. Doch die Fähigkeiten von L-Carnitin gehen weit
über die eines „Fatburners” hinaus. L-Carnitin ist an vielen biochemischen Prozessen
im Organismus beteiligt. In konzentrierter Form zugeführt hat L-Carnitin gezeigt,
dass es in Schwangerschaft und Stillzeit Mutter und Kind vor Erkrankungen bewahren
kann, sich bei Herzerkrankungen günstig auf das Herz auswirkt, die Insulinsensitivität
verbessert, die Regeneration der Muskulatur nach Belastung fördert und oxidativen
Stress reduziert. Der menschliche Körper kann L-Carnitin aus den Aminosäuren L-Lysin
und L-Methionin selbst herstellen. Eine Supplementation von L-Carnitin ist sinnvoll
in Phasen eines erhöhten Carnitinbedarfs oder eines Carnitinmangels, wie er zum Beispiel
bei Dialysepatienten und sekundär in der Schwangerschaft auftreten kann. Auch bei
Ausdauersport und vegetarischer Ernährung finden sich deutlich erniedrigte L-Carnitin-Spiegel.
Abstract
The natural substance L-Carnitine transports long-chain fatty acids from the cytosol
to the interior of the mitochondria, were they are burned. Therefore L-Carnitine is
the key substance for the generation of energy from fats, but it is much more than
a mere “fat burner”. L-Carnitine is involved in many biochemical processes in the
organism. If L-Carnitine is administered in a concentrated form, the following effects
have been shown: during pregnancy it can protect mother and child from diseases, in
the case of heart diseases it has a positive effect on the heart, it improves the
insulin sensitivity, it stimulates the regeneration of the muscles after strain, and
reduces oxidative stress. The human body itself can produce L-Carnitine from the amino
acids L-Lysine and L-Methionine. A supplementation of L-Carnitine makes sense during
phases of an increased need for carnitine or in the case of a carnitine deficiency,
as it can occur in dialysis patients and secondary during pregnancy. During endurance
sport as well as a vegetarian diet there are significantly reduced levels of L-Carnitine.
