One month's administration of creatine (CR) in the dose of 5 g/day to 11 young active sportsmen affected their daily amount of CR and creatinine excreted into urine. The probands were divided into 4 groups, according to the amount of CR found in urine, and of folates and of vitamin B12 determined in blood. The ganges of folates and vitamin B12 were mutually reciprocal. Each group utilized CR as donor of one- and two-carbon (1C and 2C) units by means of homocysteine (HoCySH), folates, and vitamin B12, in different metabolic pathways. In 10 men the CR administration was accompanied by an increase of HoCySH level in blood, while for the last man, with accidentally discovered hyperhomocysteinemia, after the month's CR administration the HoCySH level dropped by 50 %.
