L-carnitine, also known as 1-Propanaminium, 3-carboxy-2-hydroxy-N,N,N-trimethyl, or 3-hydroxy-4-(trimethylammonio)butanoate, is an amino acid produced by our body and is essential for the proper function of our cells. Its main role is to transfer fatty acids from the blood to the mitochondria, which are the energy-producing cells. Without sufficient amounts of L-carnitine, our body cannot effectively use fats as an energy source, which can lead to various health problems.
L-carnitine is mainly used in health care and nutritional supplements. As a drug, it is prescribed for certain metabolic disorders that cause a deficiency of this amino acid in the body. As a nutritional supplement, it is especially popular among athletes and people seeking fat loss. Furthermore, L-carnitine is also found in certain foods such as red meat, fish, poultry, but also nuts and seeds, and is therefore an important component of a balanced diet. In addition, it is also used in the cosmetic industry, where it is added to some creams and lotions for its positive effect on skin health.
