Olympian Labs L-Carnitine Fumarate - L-Carnitine is an essential nutrient first found in muscle extracts in 1905. Later, in 1927, the chemical structure of L-Carnitine was confirmed. This vitamin-like nutrient, also known as Vitamin BT wasn’t available commercially until the 1980’s. L-Carnitine’s main responsibility is that of energy production and proper fat metabolism.

L-Carnitine is found most often in meat and meat extract. In the human body, L-Carnitine is found abundantly in heart and skeletal muscle. It can be synthesized in the human liver, but insufficient amounts are produced in infants, in adolescents and in adults under certain physiological conditions. Two essential amino acids, lysine and methionine, are required for L-Carnitine bioynthesis,. Vitamin C, Iron, Vitamin B6 and Niacin are also involved in a sequence of enzymatically catalyzed reactions. It is evident that a lack of availability of any of these essential nutrients would greatly impair the body’s ability to synthesize L-Carnitine.
