In fact, carnitine is not an amino acid, but the chemical structure of this substance is very similar to amino acid structure. That’s why it got this classification. One function of carnitine – is the transport of fatty acids, in the oxidation process of which are produced energy. In other word, it contributes to processing fats into energy, preventing thereby the deposition of fat.
Another important feature of this substance – is decreasing level of triglycidyl in the blood, which leads to weight loss.
People gets carnitine from natural products of animal origin: meat, fish, poultry, eggs, and also synthesized in the body as long as such amino acids are available as methionine, and lysine.
If carnitine is not enough in your body, may occur the following symptoms: obesity, fatigue, heart pain.
Of all the forms of carnitine (D, L-carnitine, D-carnitine, L-carnitine, acetyl-L-carnitine), preference should be given to the last two, as the D-carnitine not only is inefficient, but also minimizes the effect of L-carnitine, as long as both form are combined in the supplement.
