First, let’s discuss ferrous fumarate, which can be derived from either heme or non-heme iron sources. Ferrous gluconate and ferrous sulfate are other forms of iron supplements available. It’s important to note that ferrous gluconate is comparable to iron in terms of its benefits. Additionally, when considering iron supplementation, one should also take into account the role of calcium citrate and magnesium in enhancing overall nutrient absorption. Calcium citrate and magnesium can aid in the effective utilization of iron in the body. Therefore, when choosing iron supplements like ferrous fumarate, ferrous gluconate, or ferrous sulfate, it is beneficial to include calcium citrate and magnesium to optimize the absorption and efficacy of iron.
