If you human long-term lack of elemental iron, or iron absorption is hampered by the human body, it will be difficult to produce hemoglobin, causing reduced blood pigment, or even a iron-deficiency anemia. At this point blood oxygen, pale skin, fatigue, and inability to affect overall physiological

If the human body lacks the hard element for a long time, or when receives the barrier to the hard element absorption, in the human body on with difficulty produces the hemoglobin, creates the hemoglobin to reduce, even occurs lacks the iron anemia.This time the blood reduces for the oxygen ability,

If human long-term lack of iron, or iron absorption affected by obstacles, makes it difficult to produce hemoglobin in human body, contribute to a lower haemoglobin, and even iron deficiency anemia occurs. Reduced blood oxygen capacity, colour white, makes people feel tired and were unable to affect
