Iron is one of the elements indispensable to life, being absolutely necessary for the synthesis of hemoglobin in erythrocytes (red blood cells), myoglobin in muscle cells and some essential enzymes. Iron contributes to general physical development, boosting immunity and relieving signs of fatigue. It is used in the prophylaxis and treatment of iron deficiency anemia. Deficiency in these elements can also cause brittle hair and nails, flaking of the skin, fatigue and dizziness. The amount of oxygen that reaches the brain, heart, liver, muscles and other tissues largely depends on this element. Iron plays an important role in maintaining the health of the immune system and in the production of energy. The most important function of iron is the production of hemoglobin and the supply of red blood cells with oxygen. As a component of the enzyme called catazan, it plays a role in combating the harmful effect of free radicals. It helps the development and regeneration of cells. It is not synthesized in the body and therefore an appropriate exogenous supply is required, achieved through the use of dietary supplements.
