Concentration of macro- and microelements in physically active students’ hair under the influence of multivitamins and minerals intake

Abstract

Summary The members of the first group (I) (n = 15) consumed food supplements and minerals complex 'Century Formula', produced by the USA company 'Swanson', for 20 days, 1 pill per day (1 pill mass -1.5 g). The members of the second group (II) (n = 15) did not consume any food supplements. The first study was carried out prior to the consumption of the supplements; the second study took place after 4-5 days after having consumed vitamins and minerals complex 'Century Formula' for 20-days period. Hair multi-element analysis was executed by applying the method of X-ray fluorescence and using the device CEP-1 ELVAX (MP.MN 3730-2011). Hair investigation was performed in Yanka Kupala State University of Grodno (Republic of Belarus).Based on the data of our research, X-ray fluorescence method was a promising and informative way for establishing the mass fraction of macro-and microelements in physically active persons ' and elite athletes' hair
