[Effect of the combined use of flavin coenzyme preparations and pyridoxine on the body vitamin balance in animals].

The effect of combined administration of flavin coenzymes and pyridoxine on B2-avitaminosis rats' supply with these vitamins has been studied. It has been disclosed that pyridoxine promotes more effective normalization of riboflavin and pyridoxine balance in the body, this balance being measured from the excretion of riboflavin and 4-pyridoxin acid with urine as well as from the content of total flavins in blood and tissues. In vitamin B2 lack, it is recommended that pyridoxin be combined with flavin mononucleotide and in particular with flavin adenine dinucleotide.
