Additional Information

L-Carnitine is a non-essential amino acid that helps to maintain overall good health by facilitating the transfer of fatty acid groups into the mitochondrial membrane for cellular energy production.* It naturally occurs in red meat and other animal source foods, but we recommend supplementation to obtain optimal levels of this excellent amino acid.

Natural color variation may occur in this product.
