Pyruvate is a 3-carbon energy intermediate produced in cells from glucose, en route to creating ATP (the main energy currency of working cells). Pyruvate supplementation has been proposed to enhance work output and weight loss by providing more efficient energy that bypasses the ability of the body to store glucose as body fat.
Many claim that calcium pyruvate can help with weight and/or fat loss. In theory, since it is the raw material for cellular respiration, supplementing with calcium pyruvate should increase the amount of energy burned, therefore allowing for more fat burning. The question is whether this is actually the case.
