High Iron Levels Linked to High Blood Pressure

Poor diet, blood cell destruction from activities such as jogging, and menstruation can all lead to iron-poor blood. To compensate, many people take iron supplements and eat foods high in iron to boost intake. You can get too much of a good thing. High iron (ferritin) levels in men are linked to high blood pressure and heart disease— according to a study from Kyung Hee University School of Medicine in Korea. Humans have a limited capacity to get rid of iron, so it can build up if you consume too much. Excessive blood iron can promote tumor growth, speed cell membrane breakdown and increase the risk of heart attack. In women, high levels of serum ferritin (a good measure of total body iron stores) was related to increased risk factors of heart disease, such as high blood pressure, body mass index (the proportion of weight to height), total cholesterol and triglycerides, and low HDL cholesterol.
