Feroglobin capsules are a gentle iron supplement with zinc and b vitamins, formulated to deliver an ideal amount of iron to the body while remaining gentle on the stomach. As well as being important for your blood, iron contributes to the normal function of the immune system and normal cognitive function. Iron is important for a number of functions in the body, but sometimes our diets are not well balanced and everyday activities, even drinking tea or coffee, can inhibit iron absorption.
