karniitina

Karniitina, also known as carnitine, is a quaternary ammonium compound that plays a vital role in cellular energy metabolism. It is synthesized in the body from the amino acids lysine and methionine. Karniitina is primarily found in muscle tissue and is essential for the transport of long-chain fatty acids into the mitochondria, where they are oxidized to produce energy.

There are two main forms of karniitina: L-karniitina and D-karniitina. L-karniitina is the biologically active form and is the one typically supplemented. D-karniitina is not biologically active and can potentially interfere with the function of L-karniitina.

Karniitina can be obtained from dietary sources, with red meat being a particularly rich source. It is also available as a dietary supplement. Deficiencies in karniitina can occur due to genetic disorders, certain medical conditions like kidney disease, or through inadequate dietary intake. Symptoms of deficiency can include muscle weakness, fatigue, and impaired heart function.

Supplementation with karniitina is often explored for various health purposes, including improving athletic performance, aiding in weight management, and supporting cardiovascular health. However, scientific evidence for these applications varies, and it is advisable to consult a healthcare professional before using karniitina supplements. The body typically regulates karniitina levels, and excessive intake is generally excreted.
