Hematocrit is the percentage of red blood cells in your blood. A low hematocrit can lead to anemia, which can cause fatigue, weakness, and shortness of breath. There are a number of things you can do to boost your hematocrit, including taking iron supplements, eating a healthy diet, and getting regular exercise.
Iron is an essential mineral for the production of red blood cells. If you are deficient in iron, your body will not be able to produce enough red blood cells, which can lead to anemia. Iron supplements can help to increase your iron levels and boost your hematocrit.
