Iron holds the key to many bodily functions. Besides being used to make hemoglobin, a protein in red blood cells that carries oxygen from the lungs to all parts of the body, it also helps produce myoglobin, a protein that provides oxygen to muscles.
Additionally, sufficient levels of iron in the body helps boost the immune system. A healthy immune system ensures overall wellness of the body and mind and keeps severe illnesses at bay. Given that iron produces hemoglobin, which in turn provides oxygen to damaged cells, tissues, and organs, it helps fight infectious diseases and viral illnesses.
Apart from the above mentioned functions and benefits of iron, experts have also linked iron deficiency to low cognitive powers. This means that a stable iron content in the body improves brain functions. It improves focus and boosts memory.
