Glycocyamine increases the production of creatine in the body. It is an immediate precursor of creatine and is transported to the liver and kidneys, where it is converted to creatine in the presence of betaine. Glycocyamine also appears to enhance glucose and creatine uptake by muscle cells. One caveat is the risk factor involved with it. Studies reveal that it can increase homocysteine-a protein associated with heart disease.
