Iron has several functions in the human body, contributing to good health and proper functioning.
Iron is one of the most vital minerals for our cells. Our primary energy source is food, and our cells need Iron to convert food into energy. The more Iron you have in your body, the more energy you will have. However, an excess of Iron can lead to some health problems, so stay within the recommended range.
Reduction of tiredness and fatigue
A 2012 study showed that women who took iron supplements experienced 48% less fatigue than women who didn’t take them . This study explains why Iron is so important, especially for those who need to produce more energy, like endurance athletes. Meeting your daily iron needs may help you feel energised and meet life’s challenges at work or home with family and friends.
Iron is essential for cognitive function, including memory, problem-solving, concentration, and learning. Your brain will perform at its best if your body has enough Iron in its system. In that case, you may not need to drink coffee every 2-3 hours to improve your concentration.
There’s a significant link between Iron and the immune system, and Iron is a critical mineral that helps create cells and grow. Moreover, Iron plays a role in your immune health because it is necessary for immune cells proliferation and maturation, particularly the lymphocytes, associated with your body’s general response to infection.
One of the most essential functions of Iron is the transportation of oxygen in the hemoglobin of red blood cells throughout your body so your cells can produce energy. Also, Iron improves oxygen storage through myoglobin. Myoglobin is a protein that transports and stores oxygen within your muscles. Myoglobin contains Iron.
Formation of red blood cells and haemoglobin
Iron is involved in heme synthesis, and it forms haemoglobin, a protein in your red blood cells. Haemoglobin transports oxygen from your lungs to your body’s tissues to help you maintain essential life functions. Without this process, your body won’t be able to get enough oxygen, and you’ll start feeling tired or fatigued.
The first and most important thing you need to realise about Iron and iron supplementation is that iron needs differ from person to person.
You might think that’s obvious, but if you were to Google “How long does it take for iron supplements to work?” you’ll mostly find specific answers like two weeks, two months, or even two years. Active Iron is clinically proven to increase iron levels by 94% within six weeks.
