Hemfer Syrup works by managing biotin deficiency as well as normalising the formation of red blood cells and nerve tissues. It functions as a dietary supplement to manage iron deficiencies and regulates oxygen in the blood. The combination of ferrous glycine sulphate, folic acid, cyanocobalamin, D-biotin, and zinc sulphate monohydrate helps manage iron deficiency anaemia, a condition where the body lacks sufficient red blood cells due to low levels of iron.
