Ferrous sulfate, providing 45 mg of elemental iron, is a gentle source of iron often preferred for supplementation. Among other iron compounds, ferrous bisglycinate and ferrous fumarate are also popular options. Additionally, the formulation may include ferric sodium EDTA to enhance iron absorption.
When considering iron supplements, it’s important to note the role of calcium carbonate and calcium citrate. These compounds can influence the bioavailability of iron. It’s generally recommended to separate the intake of calcium carbonate or calcium citrate from iron supplements to maximize iron absorption and effectiveness.
Overall, ferrous sulfate and its alternatives, such as ferrous bisglycinate and ferrous fumarate, offer various choices for those in need of iron supplementation, but attention must be paid to the presence of calcium carbonate and calcium citrate to ensure optimal absorption of iron.
