The effect of a diet containing natural zeolite (clinoptilolite) on the deformability of red blood cells of volunteers of both sexes, of a wide age range living in KhMAO-Yugra (Khanty-Mansiysk), was studied. Natural zeolites, according to literature data, have antioxidant, membrane-protective and hematostimulating properties. It has been shown that the use of zeolite powder by volunteers for 30 days causes an increase in the erythrocyte deformability index (determined by laser diff ractometry) compared to measurements taken before the start of the study.
