Iron-From a Nutritionist’s Perspective

Iron-From a Nutritionist’s Perspective

Iron is necessary for proper growth and development in the human body. The main component that constitutes Iron is hemoglobin, which also plays its part in myoglobin formation and function. Hemoglobin is the main component of blood that oxygen from the lungs and takes it to all aspects of the body. Below are some facts explaining the critical role of Iron in the body’s functioning:

Human Body Iron Requirements:

An adult must take 1.8 mg of Iron daily from different sources as 30 percent of daily consumed Iron is absorbed and used by the body. Vitamin C is also recommended along with Iron because it aids our body in absorbing Iron.


You can get Iron from veal, lean beef, turkey, lamb, chicken, liver, fish, shellfish, sweet peas, broccoli, kale, tofu, tomatoes, corn, green beans, tomatoes, sprouts, beets, and cabbage.

Role Of Iron In Blood Production:

Why is Iron essential in blood production?

About 70 percent of Iron in the body is in blood. It makes up the structure of hemoglobin as it is the central component. It carries oxygen from the lungs and transports it to all the body parts. In a case of iron deficiency, blood production ceases, and a person becomes anemic and eventually dies at the end. Similarly, myoglobin is present in muscle cells and accepts stores and releases oxygen in muscles.

Iron depletion is when the body’s intake of Iron is low, and so is its quantity in the body. This state leads to iron-deficient erythropoiesis, leading to iron anemia when left untreated.

Iron-dependent Enzymes Production

Iron is inevitable for the functioning of iron-dependent enzymes. There are numerous enzymes in which Iron acts as a cofactor. The enzymes involved in oxidative phosphorylation are the most significant ones, and they are involved in the metabolic pathway, which converts nutrients to energy. These enzymes and the cytochrome enzymes bind the haem group and have iron-Sulphur centers that play a pivotal role in their functioning.

Role Of Iron In Cell Division:

Iron is involved in mitosis, which is an essential process in the cell cycle. As the cells divide, new cells are formed which have the same number of chromosomes as the parent cell. In this way, the process of growth occurs. Hence, Iron is crucial for accomplishing cell division processes, specifically mitosis.

Coping With Fatigue And Tiredness:

It has been observed that women who take iron supplements regularly face fewer issues regarding muscle fatigue and tiredness. According to the latest research, iron supplements help cope with muscle fatigue during pregnancy and adolescence, up to 48%, compared to those who don’t have enough Iron in their diet.

Role Of Iron In Strengthening The Immune System:

Iron moderates the immune system and the body’s normal functioning. Iron is the core factor responsible for the maturation and proliferation of the cells constituting the immune and lymphatic system of the human body, especially the lymphocytes. Hence, Iron is vital in defending our body against microbial or viral infections, thus strengthening the human immune response.


All the facts, as mentioned earlier, make it clear that Iron has a primary role in maintaining the human body’s structural and functional efficiency, ranging from the production of enzymes and lymphocytes to the strengthening of muscles. Therefore, everyone must monitor the intake of Iron as the doctor recommends.
