L-carnitine in fitness science

What is L-carnitine?

L- carnitine, also known as L-carnitine, translated into carnitine in Chinese, is an amino acid that promotes the conversion of fat into energy. Red meat is the main source of L-carnitine, which means L-carnitine is an amino acid derivative separated from meat, so it is called "meat" alkali.

The role of L-carnitine

1, to help burn fat

L-carnitine is an essential coenzyme in the process of fat metabolism, which can promote fatty acids to enter mitochondria for oxidative decomposition.

The metabolic process of fat goes through an obstacle, that is, mitochondrial membrane. Mitochondria can burn fat to release energy, which is consumed by the body, but long-chain fatty acids cannot pass this obstacle smoothly. Therefore, L-carnitine has played the role of a porter! Take the long-chain fatty acids out of the protective cover bit by bit and send them to mitochondria for further oxidation!

2. Enhance endurance and improve athletic ability.

L-carnitine can promote the oxidation and energy supply of fatty acids through mitochondrial membrane, so it can promote fat burning in the body to provide energy during exercise.

At the same time, L-carnitine can also promote the oxidation and utilization of branched-chain amino acids, and change the activity of respiratory enzymes in mitochondria, thus improving the ability of aerobic oxidation.

3. Promote fatigue recovery

Excessive lactic acid production during exercise will increase the acidity of blood and tissue fluid, reduce the production of ATP and lead to fatigue. Supplementing L-carnitine can promote the activity of pyruvate deaminase in cells, thus promoting the oxidation and utilization of glucose, which is conducive to delaying the occurrence of fatigue during exercise.

Simply put, when exercising, the liver sugar function in the body will be consumed first, and when the liver sugar is not enough, fat will be consumed for energy supply. At this time, if carnitine in the body is insufficient and fatty acid consumption can't keep up, it will lead to anaerobic metabolism of sugar or glucose in the liver, and lactic acid accumulation will lead to fatigue.
