L-Carnitine Biologically, this essential amino acid serves as a fat shuttle that moves long chain fatty acids into the “furnace” of the cell, the mitochondrion. This means that when you take a supplement of L-Carnitine, that you will be able to burn fat quicker. Fat provides a valuable source of energy for muscles, including the hardest working muscle in the body, the heart. https://www.nationalnutrition.ca/articles/supplements/carnitine/ #Supplements
