To be used as a food supplement – as an additional source of Acetyl-L-Carnitine

It is recommended to consult a medical specialist before taking the supplement.

L-Carnitine is an indispensable component of nutrition allowing optimal development of the human body. L-carnitine is an amino acid that delivers fat to the muscles, where it is burned to produce energy. L-carnitine plays a huge role in the metabolism of fats. As a result, it helps to increase endurance during training and the provision of oxygen to cells. L-carnitine enhances protein synthesis and fatty acid transport to mitochondria, where they burn to synthesize energy. L-carnitine is especially often used in sports, as well as during diets.

L-carnitine is an amino acid, vitamin-like substance, in its characteristics, close to the vitamins of group B. Acetyl-L-carnitine is absolutely necessary for the normal supply of the body with its own energy and for the metabolism of fats, and, therefore, for all life processes.


Acetyl-L-Carnitine can be used to address chronic fatigue, weight gain, and decrease in physical activity. It can be used to compensate the lack of L-Carnitine in a body, i.e. during the periods of increased mental activity, heavy physical or emotional stress or during sports training. The supplement can be used to normalize body weight.

Intended effects

Acetyl-L-Carnitine has a wide spectrum of action:

  • activates the process of metabolism;
  • helps to convert fat into energy;
  • reduces fatigue during prolonged brain activity;
  • increases the performance and endurance of the body during sports or any other physical activity;
  • provides a feeling of cheerfulness.
