Pyruvate is a key metabolite of carbohydrate metabolism that is needed to begin the citric acid cycle, the process by which cells produce energy in the form of ATP. As the main chemical fuel of the body, ATP powers most vital functions throughout the body, including muscular movement. Pyruvate is also important in a number of other metabolic pathways, including those that result in fat and protein metabolism, as well as in glycogen storage. Pyruvate can therefore help to readily replenish cellular fuel supply and facilitate energy production.* Not manufactured with yeast, wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients.
