L-Carnitine is a non-essential amino acid that helps maintain general health by facilitating the transfer of fatty acid groups into the mitochondrial membrane for cellular energy production. It is naturally found in red meat and other animal-based foods, but we recommend supplementation to achieve optimal levels of this excellent amino acid. Protocol For Life uses only Carnipure™, a special quality of L-Carnitine (L-Carnitine tartrate) and the most sought-after form and brand, manufactured by the Swiss life sciences company Lonza. Protocol For Life L-Carnitine is the purest, clinically tested, and vegetarian (non-animal origin) form.
