NOW® L-Carnitine Liquid provides all of the extensive benefits of Carnitine in a highly absorbable liquid form. 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. NOW® L-Carnitine is the purest form, clinically tested, and vegetarian (non-animal sourced). CarnipureTM offers purest L-Carnitine and is a registered trademark of Lonza, Ltd., Switzerland. NOW L-Carnitine 2X Liquid provides double (1 g) the potency of competing brands per serving size.
