Carnitine’s most important known metabolic function is to transport long chain fatty acids into the mitochondria of muscle cells for oxidation. Cardiac muscle is especially dependent upon this mechanism as an important source of metabolic energy. Due to its physiological role, L-Carnitine supplementation is often chosen by sports people. In addition carnitine has a role in the thermogenesis (heat production) of brown adipose tissue, and in the regulation of gluconeogenesis. For this reason it is often taken as a supplement by slimmers. Although the body can make carnitine from the essential amino acid, lysine, a dietary source is important. The main source of carnitine in our diets comes from red meat and dairy foods, whilst dietary supplementation of L-Carnitine can safeguard intake of this metabolically essential substance. Lamberts® L-Carnitine is a pure, free-form amino acid that is ready to be absorbed by the body without needing to be broken down by digestive enzymes. Each capsule provides a full 500mg of L-Carnitine, a useful level compared to the amount provided by the average diet.
