Iron: Helps transport oxygen to cells. Aids the body in producing energy from foods.
Iron is an important component of hemoglobin, the substance in red blood cells that carries oxygen
from your lungs to transport it throughout your body. Hemoglobin represents approximately two-thirds
of the body’s iron. A lack of red blood cells leads to anemia. Anemia can affect everything from your
cognitive function to your immune system.

Iron is essential in transporting oxygen throughout the body. This is a vital function of iron, as oxygen is
required by each and every organ system to perform routine functions.
Iron is present in the muscle tissues and helps to provide the supply of oxygen required for contraction
of muscles. Without iron, muscles lose their tone and elasticity. Muscle weakness is one of the most
obvious signs of anemia.
Since oxygen supply in the blood is aided by iron and the brain uses approximately 20% of the blood
oxygen, iron is directly related to brain health and its functions. Proper flow of blood in the brain can
stimulate cognitive activity and help to create new neural pathways to prevent cognitive disorders like
dementia and Alzheimer’s disease, so proper iron intake and its subsequent brain oxygenation is
