More info coming . Naturally occurring in the body as a byproduct of carbohydrate metabolism that ultimately yields pyruvic acid. This is unstable outside the body, so scientists stabilize by combining it with sodium and calcium, hence 'calcium pyruvate'. It's thought that pyruvate can enhance energy and endurance by increasing the amount of glucose the muscle cells can take in from the blood. Exercising cells can then burn the glucose for more energy.
Some research suggests pyruvate can also aid in fat loss .
Suggested dose is 3 grams a day for endurance and energy and 5-7 grams for fat loss. New info on pyruvate forthcoming. Fast becoming the latest craze in supplementation, glutamine can do several things. First, because it makes up a substantial part of muscle, the cells there absorb quickly and put it to work to rebuild and volumize the muscles. Also, glutamine can enhance the immune system, especially important after a big workout, and help the body to recuperate from stress.
