What is Ferro Sulfate?
Ferro sulfate, also known as iron(II) sulfate, is a type of iron salt. It is manufactured through the oxidation of pyrite, or by treating iron with sulfuric acid. It is often found as blue-green heptahydrate crystals.
Ferro sulfate is commonly used to enrich foods and supplements with iron, which is an essential mineral for the production of hemoglobin in red blood cells. There is substantial evidence supporting its ability to help prevent iron deficiency anemia. However, excessive intake could lead to gastrointestinal discomfort.
On a label, ferro sulfate is typically listed for its iron content. Consumers focusing on maintaining adequate iron levels without supplements should be aware of its presence in fortified foods.
