Levo-body-building beverage is an amino acid-like substance that converts fat into heat. L-carnitine is indeed a kind of fat transporter, which can promote fatty acids to enter mitochondria for oxidative decomposition. However, a normal and healthy human body will not lack L-carnitine, and the human body can produce L-carnitine by itself.

Physiological function of left-handed exercise

L-carnitine is widely distributed in nature, and the content of carnitine in muscle tissue is high. Animal experiments show that the concentration of L-carnitine in adrenal gland is the highest, followed by heart, bone, muscle, adipose tissue and liver. Free L-carnitine is excreted in urine. Carnitine is required by human body through dietary intake and/or endogenous synthesis.

Carnitine can be synthesized from lysine and methionine in human liver and kidney, with the help of VC, nicotinic acid, VB6 and iron. VC is necessary for the biosynthesis of carnitine. Among all nutritional auxiliary factors, VC has the greatest influence on the biosynthesis speed of carnitine. Experiments show that the speed of carnitine biosynthesis in kidney of vitamin-deficient guinea pigs is reduced by 8 ~ 10 times, especially in heart and skeletal muscle.

The concentration of carnitine in the above tissues of animals lacking VC decreased by 50%. Iron is also needed in the reaction that needs VC, and the concentration of carnitine in liver and heart tissue of pregnant rats with iron deficiency is obviously reduced.
