L-Carnitine is an amino acid (a building block for proteins).
Red meat and dairy produce are the primary dietary sources but it is also naturally produced in the body, helping to produce energy.
Carnitines carry certain fatty acids to the mitochondria to be burned as fuel; in this way L-Carnitine works with the mitochondria, known as the powerhouses of the cells, and helps the body to metabolise fat.
All Carnitines are antioxidants and work in different, but related, ways, some are closely connected to cardiac health, some to metabolism and others to neurological health.
It is produced in the liver and kidneys, then stored in the skeletal muscles, heart and brain.
