What is Ferrous Sulfate?

Ferrous sulfate is an iron salt used primarily as an iron supplement. It is typically produced by reacting iron with sulfuric acid, resulting in a crystalline salt that can be ground into a powder or formulated into a solution.

Ferrous sulfate is commonly added to infant formulas and baby foods to prevent and treat iron deficiency anemia, which is essential for proper growth and development. While it's effective in correcting iron deficiency, it can sometimes cause gastrointestinal side effects like constipation or upset stomach.

When you see ferrous sulfate on a label, it signifies that the product is fortified with iron. This helps support the body's production of red blood cells and oxygen transportation.
