🧪 Formulation Notes

NOW L-Carnitine Liquid has all of the properties of carnitine in a highly absorbable liquid form. 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, bet 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).
