L-carnitine, also known as carnitine, is a natural vitamin-like substance that plays an important role in the body's energy metabolism. It is synthesized from the amino acids L-lysine and L-methionine and is found mainly in animal products, especially meat and dairy products.
The main function of L-carnitine is to transport fatty acids to the mitochondria, the so-called "power plants of the cells", where they are burned for energy. It therefore plays an important role in the breakdown of fatty acids for energy. This makes L-carnitine a popular dietary supplement among people seeking weight loss or improved fat burning.
In addition, L-carnitine may also help reduce fatigue and enhance athletic performance by improving oxygen transport and energy turnover in muscles. It is also discussed whether L-carnitine can have positive effects on muscle growth and recovery after exercise.
L-carnitine plays an important role in energy metabolism and can support fat burning and athletic performance. However, it is important to consider individual needs and any contraindications before taking it as a dietary supplement.
