The invention dissolves the problem of the pharmaceutical preparation being a factor stimulating the absorption of microelements. The essence of the invention is that the preparation contains alpha-keto-glutarate or/and glutamine or/and glutamate or/and ornithine of alpha-keto-glutarate, dipeptide of glutamine and other amino acids or/and tripeptides of glutamine and other amino acids or/and glutamate with other amino acid or/and salts of alpha-keto-glutarate or/and glutamine or/and glutamate or/and ornithine of alpha-keto-glutarate, dipepetides of glutamine or glutamate with other amino acid in a dose 0.01-0.5 g/kg/day and administered orally stimulates the absorption of iron, zinc, copper, manganese, strontium, calcium, phosphorus and other microelements from the alimentary canal to the blood ensuring proper--physiological--curative level of these compounds in the blood of people and animals.
