An amino acid that is crucial for the oxidation of fats to generate energy. L-Carnitine functions as a carrier for the transport of fatty acids into the mitochondria, the "energy furnaces" of the cell. Carnitine is a "semi-essential" nutrient, in that its synthesis in the body is complex and may be hindered in individuals who are nutritionally compromised.*
