Iron!
Women, this mineral is essential to your well been. Women need more iron than men to make up for the amount of iron they lose in their menstrual period. Around 1 mg of iron is lost for every day of bleeding. Iron deficiency is the most common nutrient deficiency in women. Iron is an important component of hemoglobin, the substance in red blood cells that carries oxygen from your lungs to transport it throughout your body. … If you don’t have enough iron, your body can’t make enough healthy oxygen-carrying red blood cells. A lack of red blood cells is called iron deficiency anemia.
