What percentage of Ferrous sulfate is elemental iron?

  1. 10%

  2. 15%

  3. 20%

  4. 25%

The correct answer is: 20%

Ferrous sulfate is a common iron supplement used to treat or prevent iron deficiency anemia. In this compound, the percentage of elemental iron is around 20%. This means that for every 100 mg of ferrous sulfate, approximately 20 mg is actual iron that can be absorbed and utilized by the body. It is important for pharmacists to be familiar with the elemental iron content of iron supplements to ensure proper dosing and administration for patients with iron deficiency.
