Iron is an integral part of hemoglobin, the red pigment that transports oxygen from the lungs, into the blood and to the muscles and brain. Iron is also a constituent of myoglobin, another form of hemoglobin found in muscle tissue, and certain essential enzymes. One third of hemoglobin stores are found in the body in the form of ferritin and hemosiderin, stored mainly in the bone marrow and liver. If dietary intake is insufficient, the body uses its deposits and anemia occurs. Anemia is the most obvious symptom of iron deficiency and is characterized by a significant reduction in the oxygen that the blood can transport, which results in generalized fatigue. Additionally, iron deficiency has been related to a decrease in immune system function, which increases the risk of contracting diseases. Iron in the form of pyrophosphate is absorbed better than any other type, so if there is a deficiency, this form does not cause digestive discomfort, nor does it produce super dark stools, which indicates that too much oxidation is being generated in the digestive tract. . Women who suffer from very heavy periods lose a lot of iron and it is necessary to highlight that this mineral is very important for the function of the thyroid and if its function is affected it can prevent the production of dopamine and cause prolactin to rise and when it rises The production of progesterone is hindered. We must also not forget that when dopamine is low it can prevent optimal rest. Iron is widely distributed in foods, but the most organic is that which comes from animal sources such as red meat, meat organs, poultry and fish, then comes molasses, nuts, clams, legumes and bread. In this formula, iron pyrophosphate is combined with vitamin C and folic acid, two cofactors that favor its better absorption and use by the body.
