L-Carnitine is referred to by many as a "fat burner" and is recommended for weight loss. It is a naturally occurring protein compound that is important for fat metabolism. The name L-carnitine is derived from the Latin word carnis, which translates as meat. Carnitine is namely formed from amino acids that are mainly found in red meat.
L-carnitine is basically a substance produced by the body in the liver, kidney and brain. The body can synthesize it from the two amino acids lysine and methionine. Therefore, it does not need to be added from the outside to ensure the functioning of the organism. On average, 15 mg are produced by the body per day, while an additional 10-70 mg are absorbed through protein-rich food.
In the body, L-carnitine acts as a transport molecule, as it ensures that the long-chain fatty acids from the fat and muscle tissue reach the mitochondria. Once there, they are burned in a special process called beta oxidation.
The benefit of L-Carnitine
L-Carnitine can support a diet in a natural way and without any side effects. It helps the body to get the required energy from the fat cells and thus ensures better fat burning. This effect was proven in 2002 by some scientists from the University of Leipzig and later confirmed by researchers from the University of Rostock.
Strength and fitness athletes also prefer L-carnitine, as it is very well tolerated and does not put a strain on the cardiovascular system. With the support of L-Carnitine, additional muscle mass can be built up within a short period of time. Vegetarians and vegans also like to resort to L-carnitine to prevent an undersupply due to the lack of meat consumption.
In addition, L-carnitine strengthens the immune system, increases endurance performance, promotes concentration and helps with fatigue. Certain clinical pictures, such as Crohn's disease, also benefit from an additional intake of L-carnitine. It also participates in many biochemical processes in the organism in a direct or indirect way. L-carnitine can bring about an improvement in blood lipid levels and have a positive effect on existing heart disease.
The intake of carnitine
It is recommended to take L-carnitine on an empty stomach, if possible, because only then it can develop its full effect. Athletes should usually take it before training. The recommended daily dose is up to 2 g distributed throughout the day. If taken sensibly, it is usually not possible to overdose, because excess L-carnitine is excreted without any problems.
L-carnitine can be taken as a dietary supplement to boost the metabolism. In combination with a balanced diet and sufficient exercise, it can support the body's weight loss and have a positive effect on physical performance.
