L-Carnitine L-Tartrate
A form of carnitine that aids in fat metabolism and may improve exercise recovery.
Also known as: LCLT
Overview
L-Carnitine L-Tartrate (LCLT) is a supplement that combines L-carnitine with tartaric acid. L-carnitine is an amino acid derivative that plays a crucial role in energy production by transporting fatty acids into your cells' mitochondria. The mitochondria act as engines within your cells, burning these fats to create usable energy. LCLT is a popular form in sports nutrition for its rapid absorption rate. It is suggested to aid in fat loss, increase energy, and reduce muscle soreness after exercise.
