What are the functions and benefits of L-carnitine?

L-carnitine generally promotes fat metabolism, enhances exercise endurance, improves cardiovascular health, assists in weight loss, and protects the liver. A detailed analysis is as follows:

1. Promotes fat metabolism: L-carnitine transports fatty acids into the mitochondria for oxidation and decomposition, thereby providing energy to the body. This process helps reduce fat accumulation.

2. Enhances exercise endurance: By improving the utilization of fat, L-carnitine delays glycogen depletion and increases energy supply during physical activity, thus helping to improve exercise endurance and stamina.

3. Improves cardiovascular health: L-carnitine lowers blood triglycerides and low-density lipoprotein levels while increasing high-density lipoprotein levels, helping maintain vascular health and prevent cardiovascular diseases.

4. Assists in weight loss: By accelerating fat burning and energy consumption, L-carnitine can aid in weight loss when combined with a balanced diet and moderate exercise, making it particularly suitable for individuals aiming to reduce body fat.

5. Protects the liver: L-carnitine promotes fat metabolism and reduces fat deposition in the liver, thereby alleviating the burden on the liver and offering certain improvement effects for conditions such as fatty liver.

When using L-carnitine, it is important to choose reputable products and supplement appropriately according to individual needs and physical condition. Excessive intake should be avoided to prevent adverse reactions. Additionally, combining it with a balanced diet and moderate exercise will help maximize its benefits.
