function of iron in body

Iron is one of those minerals that powers the body. It is famed for its role in keeping us healthy and sturdy. With little or no iron, our muscles alongside other cells would be fragile, as they won't be able to get the much-needed oxygen.

While iron is well-known as a mineral, little is known about its functions in the human body. This post seeks to fix that by showcasing some incredible benefits of iron in the body.

Just like every other Chewwies post we reveal secrets for a life brimming with vitality and no room for weakness - Read on!

Functions of iron

Here is a deep dive into the fascinating world of iron, revealing its top functions;

Fuels the body cells

One of the most crucial functions of iron is the shuttling of oxygen. Iron is an integral part of haemoglobin, a molecule that carries oxygen in the blood. In the absence of iron or when its level is low, the body cannot produce enough haemoglobin.

This results in anaemia. Oxygen is the fuel for the body thus iron deficiency poses a severe threat. It's safe to call Iron the tireless builder of the oxygen highway. It makes sure every cell gets the energy it needs to function perfectly.

Energy Boosters

Do you know what happens when you lack iron? You feel tired, weak or sometimes even dizzy. Iron plays an outstanding role in the process of energy production. 

Also, iron is an excellent transporter. It ensures the body's power plants (mitochondria) keep humming with energy. Iron might be the key to infusing your body with energy and vitality for everyday run around.

Perfectly toned muscle 

Iron comes first when it comes to maintaining healthy muscles. It is a key component of myoglobin, a molecule that stores oxygen in muscle cells. When we exercise, our muscles require oxygen to function effectively. 

Iron makes this happen by supplying the oxygen in demand, improving muscle performance and preventing fatigue. Looking to get strong and well-functioning muscles? 

You might want to add an iron or a vitamin D3 supplement to your diet plan.

Enhanced brain power

Studies have drawn a clear line between iron levels and brain functions. Just like vitamin C, optimal iron level results in optimal cognitive functions. This is because human brain cells require a bulk of oxygen to carry out complex tasks. And iron ensures its delivery.

Iron helps in the production of neurotransmitters, which are responsible for sending signals between brain cells. Adequate iron levels offer improved cognitive function, memory, and concentration.

This cognitive function explains why students are often advised to nourish their brains with iron-rich foods.

Boost immune system

Iron is a key element when it comes to tackling invaders in our bodies. It fosters the replication of immune cells. From the production of immune cells to their proper functioning iron plays an outstanding role.

Thus, an adequate iron intake could be just the ammunition you need to stay healthy and protected.

Enhance heart health 

Iron has been proven to leave positive effects on the heart. A recent research by a group of scientists in the US showed how iron deficiency affects your heart. It turns out that iron deficiency makes the heart vulnerable. Hence, some heart conditions are handled by first taking back the iron levels to normal.

Iron-rich foods

Now you've got a hang of how essential iron is for your system, here are some delicious treats rich in the diet; 

  • Lean meats like beef and poultry.
  • Seafood.
  • Beans and legumes. 
  • Dark leafy greens. 
  • Fortified cereals. 
  • Nuts. 

Sometimes the process of iron absorption is quite complicated, thus pairing iron-rich food with vitamin C is recommended to enhance iron absorption.
