Iron SR is a food supplement in the form of prolonged-release capsules, based on a source of iron, folic acid and vitamins C, B6 and B12, dedicated to pregnant women. Iron helps in the proper production of red blood cells and hemoglobin and in the proper transport of oxygen in the body. Vitamin C, in turn, increases the absorption of iron and helps protect cells from oxidative stress, while folates contribute to the growth of maternal tissues during pregnancy.
