L-carnitine is popular as a potential ergogenic aid because of its role in converting fat into energy. It is essentially involved in energy production through increased fatty acid oxidation.
Essence L-carnitine. Dietary supplement in the form of capsules containing 1000 mg of L-carnitine tartrate in the portion of the product recommended for consumption during the day.
L-carnitine is an ingredient that is often used during periods of work on the figure. It is known for its role in fatty acid oxidation and energy metabolism. The energy obtained in this way can be used during physical exertion (therefore L-carnitine is often recommended for use before training and is also a component of pre-training products). Remember that the best combination is a well-balanced diet and physical activity, as well as the right amount of time needed for regeneration of the entire body.
Naturally, occurring carnitine is a quaternary amine that is present in all mammalian species. L-carnitine is synthesized endogenously in the liver, kidneys and brain from the essential amino acids lysine and methionine or consumed in animal products. Its synthesis is catalysed by four enzymatic reactions and requires the presence of vitamin C, vitamin B6, niacin and reduced iron as co-factors. L-carnitine biosynthesis accounts for only 25% of the daily requirement. Therefore, you should pay attention to food products containing L-carnitine or take care of its supplementation. It is worth noting that dietary L-carnitine intake is highly variable. It is estimated that in omnivorous humans, 75% of the body's carnitine comes from the diet. Its primary source is red meat. In contrast, plant-based foods contain negligible amounts of L-carnitine (1).
On the tissue level, the main storage of L-carnitine is found in the heart and skeletal muscle (about 95%), while much lower concentrations are found in the liver, kidneys and plasma. It is estimated that its content in muscles is about 70 times higher than in blood plasma (1).
L-carnitine is an essential transport factor for the membrane acyl-coenzyme A (CoA) and is involved in the oxidation of fatty acids in the liver and kidneys. In addition, carnitine can improve blood flow and oxygen supply to muscle tissue by improving endothelial function, thereby improving muscle regeneration. L-carnitine may also increase the general state of antioxidant enzymes, which may also affect muscle regeneration. L-carnitine has shown a potential multidirectional effect on various physiological and metabolic pathways that can improve athletic performance in both medium and high-intensity exercise (2).
L-carnitine is popular as a potential ergogenic aid because of its role in converting fat into energy. It is essentially involved in energy production through increased fatty acid oxidation. L-carnitine has been very popular for years (3). Endurance athletes use carnitine to increase fat oxidation and conserve muscle glycogen (4). However, the role of L-carnitine and its derivatives in the metabolism of carbohydrates and lipids is still under investigation (3).
