Total antioxidant capacity of blood plasma from healthy donors receiving vitamin and mineral complex.

Abstract

The total antioxidant capacity (TEAC assay) of blood plasma from healthy donors was studied before and after 2- and 4-week consumption of the vitamin and mineral complex containing the major antioxidant vitamins and cofactors of antioxidant enzymes. Before the treatment the donors were divided into 2 subgroups with initially high and low total antioxidant capacity. After 2-week course of vitamin and mineral complex the total antioxidant capacity considerably decreased in group 1 donors, but increased in group 2 donors. After 4-week course this index increased in donors of both subgroups and slightly surpassed the baseline level typical of individuals with high total antioxidant capacity.
