The role of L-carnitine

Oct 14, 2021

1. Help fat burning

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

The process of fat metabolism has to go through a barrier. The barrier is the mitochondrial membrane. Mitochondria can burn fat to release energy and be consumed by the body, but long-chain fatty acids cannot pass this barrier smoothly. So L-carnitine acts as a porter! Carry the long-chain fatty acids little by little to the outside of the shield, and send them to the mitochondria for further oxidation!


2. Enhance endurance and improve athletic ability

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

At the same time, L-carnitine can also promote the oxidative utilization of branched-chain amino acids, and can change the activity of respiratory enzymes in mitochondria, thereby improving the body's aerobic oxidation function.


3. Promote fatigue recovery

Excessive production of lactic acid during exercise will increase the acidity of blood and tissue fluid, reduce the production of ATP, and cause fatigue. Supplementing L-carnitine can promote the activity of pyruvate deaminase in cells, thereby promoting the oxidative utilization of glucose, which is beneficial to delay the occurrence of fatigue during exercise.

Simply put, during exercise, the body’s glycogen function will be consumed first. When glycogen is not enough, fat will be consumed for energy. At this time, if the body’s carnitine is not enough, the consumption of fatty acids will not keep up, which will lead to glycogen. Or glucose anaerobic metabolism, accumulation of lactic acid causes fatigue.
