(L)-Sodium lactate (Sodium L-Lactate) is produced from pyruvate by the enzyme Lactate Dehydrogenase. Lactate production occurs during anaerobic glycolysis or in proliferatively active cells. L-Lactic Acid occurs in small quantities in the blood and muscle fluid of man and animals. The lactic acid concentration increases in muscle and blood after vigorous activity. L-Lactic acid is also present in liver, kidney, thymus gland, human amniotic fluid, and other organs and body fluids.
