Key Differences Between Ferrous Gluconate and Ferrous Sulfate

1. Chemical Composition
– Ferrous sulfate contains iron bound to sulfate, providing about 20% elemental iron per dose.
– Ferrous gluconate combines iron with gluconate, offering around 12% elemental iron per dose.

2. Absorption & Side Effects
– Ferrous sulfate is more potent but may cause stronger gastrointestinal side effects, such as constipation and nausea.
– Ferrous gluconate is gentler on the stomach, making it a better choice for people with digestive sensitivities.

3. Common Uses
