Supplements generally arent recommended unless you have anemia caused from iron deficiency. Excess iron can damage organs and cause side effects such as constipation and heartburn, so its important to follow your healthcare providers dosing instructions and to pay attention to the form of iron they suggest, as there are many available (ferrous sulfate, ferrous fumarate, ferrous gluconate, etc.) and not all will be ideal for you
