L-carnitine (Levocarnitine) is constituent of striated muscle and liver. It is used therapeutically to stimulate gastric and pancreatic secretions and in the treatment of hyperlipoproteinemias.Target: OthersL-carnitine (Levocarnitine) is an endogenous molecule involved in fatty acid metabolism, biosynthesized within the human body using amino acids: L-lysine and L-methionine, as substrates. L-carnitine (Levocarnitine) can also be found in many foods, but red meats, such as beef and lamb, are the best choices for adding carnitine into the diet [1]. Administering L-carnitine (510 mg/day) to patients with the disease. L-carnitine (Levocarnitine) treatment significantly improved the total time for dozing off during the daytime, calculated from the sleep logs, compared with that of placebo-treated periods. L-carnitine (Levocarnitine) efficiently increased serum acylcarnitine levels, and reduced serum triglycerides concentration [2]. L-carnitine (Levocarnitine) and its derivatives show promise in the treatment of chronic conditions and diseases associated with mitochondrial dysfunction but further translational studies are needed to fully explore their potential [3].
