Creatine is recommended to be administered as food supplement, which should fortify its natural formation. It is supposed that human organism utilizes this compound for creatine phosphate formation, which is necessary for energy supplementation for muscular work. It was shown that the metabolic ways are more complicated than had been supposed. The changes in thiodiglycolic acid (TDGA) excretion into urine proved that application of creatine affects the metabolism of thiocompounds and two-carbon units, i.e., levels of homocysteine and glycine in blood, and of TDGA in urine. From our results, obtained in experiments with a group of 11 young men, who were supplemented by creatine for one month, it was confirmed that the dependence interrelationship among thiocompounds, vitamin B12, folates, cholesterol, and other complex is more complicated than had been supposed. For better understanding of the role of creatine in general metabolism, ...
