Hemoglobin is a vital protein found in red blood cells and its primary function is to transport oxygen from the lungs to various tissues throughout the body. According to Finnish reference values, normal hemoglobin levels are 117–155 g/l for women and 134–167 g/l for men. “The normal range is therefore quite broad, and previous studies have suggested that a hemoglobin level within the normal reference values but at the lower end of the range may be beneficial to health,” says Postdoctoral Researcher Jooa Norha from the University of Turku in Finland.
