Formulation Notes

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).
