L-LYSINE • Essential Amino Acid* • Healthy Immune Function* • Supports Calcium Absorption* • Helps manufacture protein* DESCRIPTION L-Lysine is an amino acid (a building block of protein) that is essential for health. However, it cannot be manufactured naturally in the human body like other types of amino acids. Therefore L-Lysine is considered as one of the eight essential amino acids.* L-Lysine also acts as a precursor for several other amino acids, including L-Carnitine (needed for fat metabolism). L-Lysine is crucial for the formation of collagen, a major part of the bodys connective tissues. L-Lysine also contributes to energy production when converted to acetyl coenzyme A, one of the principle fuels for the Krebs Cycle. The Krebs Cycle is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetate derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy.* * These statements have not been evaluated by the Food and Drug Administration (FDA).
