I simply do not understand these different iron supplements. I have ferrous fumarate 18mg, which is supposedly 100% DV, but other people online say they are taking hundreds of milligrams of ferrous fumarate or of ferrous sulfate. I don‘t get this.The doc said 325, didn‘t specify a type of iron. I took an extra 18mg fumarate and feel better ( the one pill wasn‘t helping me feel better.) But I don‘t know if that‘s a safe daily dosage (36mg/day.)
