Pyruvate plays a vital role in metabolism and the energy-production process. It is the link between the two main energy generating cycles in the body, glycolysis (anaerobic metabolism) and the Krebs cycle (aerobic metabolism). Source Naturals calcium pyruvate is manufactured using a unique process which ensures the product's stability and high purity. Extensive research indicates that pyruvate may play an important role in a healthy diet and exercise program. *
