L-carnitine: Properties and benefits for our body

The human body performs a large number of processes. Each of them allows you to enjoy the optimal functioning of the body. It is worth highlighting those that are related to those that provide energy . This is essential to stay active for much longer. One of the most useful elements for this is L-carnitine.

In this article we will see what L-carnitine is, what its properties are and what benefits it offers to the body.

What is L-carnitine?

L-carnitine is a molecule made up of two amino acids that the body is capable of producing on its own. For its formation, only the presence of lysine and methionine is required, which help to synthesize it in the liver and kidney. Once it is created, it acts as a conductor of fats , allowing the body to increase the presence of energy.

Depending on the amount present in the body, the person will have more or less strength , hence its importance. In the case of some people, it is possible that there is a deficiency of L-carnitine, either due to a health problem or due to the intake of high-fat foods. For this reason, they may need to ingest this molecule through supplements.

Debido a su efecto positivo en la energía corporal, se suele utilizar por deportistas y por quienes realizan una gran cantidad de actividades cada día.

Las propiedades de la L-carnitina no se limitan a producir energía, aunque sin duda es una de las principales razones para consumirla. A continuación, señalaremos otras características de esta molécula, y sus efectos en el cuerpo.


Although it is not its main characteristic, it should be noted that those who want to lose weight and, at the same time, maintain their muscle mass, have a great ally in L-carnitine, because it helps to fulfill both functions with great success. This is because it helps convert fat into energy , which is used when exercising.

In this particular, it refers to the health problems that L-carnitine deficiency can cause. For each of them, the opinion of an expert doctor is necessary, who will indicate the amount to be applied. This may depend on the age of the patient . Although each case is different, below, we will see the most frequent doses.

  • Newborns. In any presentation, 50 mg should be administered for each kilogram of the infant. This quantity must be administered in a period of 24 hours, dividing it into several parts.
  • Children and adolescents. The dose to be used should be between 50 and 100 mg for each kilogram of the patient. This amount corresponds to the maximum allowed in one day.

Some conditions may require up to 200 mg per kilogram of the person , but this depends on your health condition, as well as the opinion of the treating physician. Similarly, it is necessary to be sure that the patient does not have an allergy to any of the components of L-carnitine. This is possible, despite being a component that the body can manufacture.
