An excessive amount of fat tissue is one of the main causes of problems related to body shape... how to deal with this situation? In this context, the use of L-carnitine can be helpful, a substance that enables fighting discomfort caused by excess fat... in the following analysis, you will learn more about its properties and benefits in supplementation.
What are the detailed facts about carnitine and what are its functions?
The name L-carnitine refers to an organic compound that is produced in the human brain, kidneys, and liver. It is also a vitamin-like substance that is delivered to the body in two ways: through endogenous synthesis in the human body and through the consumption of food products in which it is found, such as lamb, fish, pork, and beef. It is worth noting that poultry meat contains less carnitine, while plant products only contain trace amounts of this substance. Carnitine primarily has a transport function, delivering fatty acids to the mitochondria, where they are converted into energy that enables the proper functioning of the body at the cellular level. Carnitine also has a detoxification function, removing fatty acids with medium and short chain length from the mitochondria. L-carnitine is used in the treatment of diseases of the circulatory system such as atherosclerosis, heart failure, and coronary heart disease, as well as in the treatment of muscle damage. It can also be helpful in the treatment of obesity and lipid disorders.
Necessity and consequences of deficiency
The ingestion of L-carnitine is especially recommended for individuals participating in intense exercise, performing heavy physical work, as well as for vegans and some vegetarians. For a healthy and adult person, the daily dose is approximately 15 mg. The body produces between 11 and 34 mg of carnitine per day, and the amount supplied with food ranges from 20 to 200 mg. A vegan or vegetarian diet contains approximately 1 mg of carnitine per day. A deficiency in L-carnitine can lead to muscle wasting (weakening or atrophy of muscle fibers) and heart failure. There are also reports of negative effects of the medication on the digestive system, such as diarrhea, abdominal pain, or nausea. On the other hand, clinical studies confirm a good tolerance of this substance by the human body.
Conclusions
In summary, L-carnitine is employed for the removal of excess fatty acids that accumulate. Its transport capability enables the conversion of surplus fatty acids into energy, which is essential during strenuous physical exertion or dynamic physical work. Additionally, L-carnitine exhibits a detoxifying effect that safeguards our body from potential cardiovascular issues and disorders of the muscular system.
